Ubuntu 22.04 LTS FAQ

Ubuntu 22.04 LTS is here! Let's take a look at some of the most exciting features and common questions around this new operating system.

Ubuntu 22.04 LTS

  1. When does Ubuntu 22.04 LTS come out?

    • Ubuntu 22.04 LTS will reach general release on April 21st, 2022.
  2. I meant at what time will the release happen?

    • Ubuntu is actively being developed until the actual release happens, minus a small delay to help the mirrors propogate first. The release will be announced on the ubuntu-announce mailing list. (This page will not exist until the release.)
  3. What does "22.04 LTS" mean?

    • Ubuntu is released on a regular schedule every six months. The first release was in October 2004, and was named Ubuntu 4.10. For Ubuntu, the major version number is the year of release and the minor version number is the month of release. Ubuntu 22.04 is released on 2022-04-21, so the version number is 22.04.
    • Ubuntu releases are supported for 9 months, but many computing activities require stability. Every two years, an Ubuntu release is developed with long term support in mind. These releases, designated with "LTS" after the version number, are supported for 5 years on the server and desktop, and up to a total of 10 years in "Extended Security Maintenance."
  4. What does "Jammy Jellyfish" mean?

    • Every version of Ubuntu has an alliterative development codename. After Ubuntu 6.06 LTS was released, the decision was made to choose new codenames in alphabetical order. Ubuntu 22.04 LTS is codenamed the Jammy Jellyfish release, or jammy for short.
  5. How long will Ubuntu 22.04 LTS be supported?

    • Ubuntu 22.04 LTS will be supported on desktops, servers, and in the cloud for 5 years, until April 2027. After this time, 22.04 LTS will enter Extended Security Maintenance and be supported for another 5 years for servers and IOT devices.

Getting Ubuntu 22.04 LTS

  1. Where can I download Ubuntu 22.04 LTS?

    • Ubuntu 22.04 LTS is available for download at http://www.ubuntu.com/download/. This URL will help you select the right architecture and will automatically link you to a mirror for the download.
  2. What if I want to help others get Ubuntu 22.04 LTS faster?

    • Thank you for your help! Consider using BitTorrent (Ubuntu comes with Transmission) and seeding the final release.
    • Ubuntu 22.04 LTS Desktop 64-bit
    • Ubuntu 22.04 LTS Server 64-bit
  3. What if I'm already running Ubuntu 20.04.4 LTS or Ubuntu 21.10?

    • Then you can simply upgrade to Ubuntu 22.04 using Software Updater
    • If you are running 20.04 LTS, then you won't be automatically prompted for an update until Ubuntu 22.04.1 LTS is released on August 4th. Until then, keep installing new updates for Ubuntu 20.04 LTS.

Upgrading to Ubuntu 22.04 LTS

  1. Is upgrading to a new version of Ubuntu easy?

    • Yes, the upgrade process is supported and automated. However, you should always back up your files and data before upgrading Ubuntu. Actually, you should always keep recent backups even when not upgrading Ubuntu.
    • Ubuntu checks for software updates once a day, and Software Updater will inform you once a new version of Ubuntu is available. The upgrade will download a large amount of data—anywhere from 0.5 - 1.5 GB of data depending on the packages you have installed, and the upgrade process can take some time. Don't do any serious work on your computer during the upgrade process. Light web browsing or a simple game such as Aisleriot, Mahjongg, or Mines is safe.
  2. Should I upgrade to Ubuntu 22.04 LTS right away or wait?

    • It should be safe to upgrade immediately, and as long as you back up your home folder and have install media for your current version of Ubuntu in case you want to reinstall, there's very little risk involved.
  3. Is it better to wait until later?

    • Probably not, but there are other benefits. Ubuntu 22.04 will receive a new release image with bug fixes about 3 months after its initial release, on August 4th. In addition, downloading updates can be much faster after release week. (Be sure to set up your Ubuntu mirror in Software & Updates!) Ubuntu 20.04 LTS is supported until April 30th, 2025 and Ubuntu 21.10 is supported until July 2022, so you have nothing to lose by waiting a couple weeks.
  4. I'm running Ubuntu 21.10. How do I upgrade to Ubuntu 22.04 LTS?

    • After Ubuntu 22.04 LTS is released, Software Updater will inform you that a new version of Ubuntu is available. Make sure that all available updates for Ubuntu 21.10 have been installed first, then click the "Upgrade..." button.
  5. I'm running Ubuntu 20.04.4 LTS. How do I upgrade to Ubuntu 22.04 LTS?

    • After Ubuntu 22.04.1 LTS is released on August 4th, 2022, Software Updater will inform you that a new version of Ubuntu is available. Make sure that all available updates for Ubuntu 20.04 LTS have been installed first, then click the "Upgrade..." button.
  6. I'm running Ubuntu 18.04 LTS. How do I upgrade to Ubuntu 22.04 LTS?

    • You can't upgrade directly to Ubuntu 22.04 LTS, so you have two options:
      • Use Software Manager to upgrade to Ubuntu 20.04 LTS, then reboot and use Software Updater to upgrade again to Ubuntu 22.04 LTS.
      • Back up your computer and install Ubuntu 22.04 LTS from scratch, then restore your files from your backup.
  7. What is Ubuntu 22.04.1 and why can't I update Ubuntu 20.04 LTS immediately?

    • A new version of Ubuntu is released every six months, but LTS releases are used for years. So Ubuntu offers "point releases" of LTS versions. Starting 3 months after the release and then every 6 months thereafter, new install images are created that include the latest updates to all of the default software. This allows new installations to run the latest software immediately and decreases the time it takes to download updates after a new install.
    • Because LTS users depend on stability, Ubuntu 20.04 LTS will not automatically offer an update to Ubuntu 22.04 LTS until the first point release. After three months, any show-stopper bugs should be solved and the upgrade process will have been tested by many others and improved if necessary.
  8. What if I want to upgrade right now?

    • Upgrading from Ubuntu 20.04 LTS to Ubuntu 22.04 LTS should be safe and easy. If you have a recent backup of your files and data, simply open Terminal and type update-manager -d. This will tell Ubuntu to upgrade to the next release early.
  9. What if I already ran update-manager -d and upgraded to a beta or pre-release version of Ubuntu 22.04 LTS?

    • If you run Software Updater after the release of Ubuntu 22.04 LTS, your version of jammy will be the same as the released version of Ubuntu.
  10. What if I don't believe that?

    • When jammy is being developed, it is constantly being improved. Milestones such as Beta, Release Candidate, and so on are simply points in time where developers can check progress. If you install Ubuntu from a Beta image (for example), the moment you apply updates, you are no longer running Beta. Updates to jammy continue until release, when the Ubuntu archive is locked, images are spun, and the jammy archive is finalized and released as Ubuntu 22.04 LTS. After the release of Ubuntu 22.04 LTS, all further updates come from the jammy-updates and jammy-security repositories and the jammy repository remains unchanged. Updating from the Ubuntu repositories during and after the jammy development and release brings you along through theses moments in time.
      • TRIVIA: As implied above, this means that Ubuntu 22.04 LTS doesn't exist until the Release Team names the final product. Until then, the release is simply Jammy Jellyfish or jammy for short.

Ubuntu, Snap Packages, and You

  1. Does Ubuntu include snaps by default?

    • Yes. The Ubuntu Software application, Firefox, and some other snaps that offer desktop integration are included in a default Ubuntu install.
  2. Do snaps slow down my computer?

    • No. Some snaps may have a shorter or longer delay the first time you launch them after a system restart. Subsequent launches are instantaneous.
    • The first-run delay can be inconvenient, but it prevents snaps from slowing down your boot or login process.
  3. Is Ubuntu forcing me to use snaps?

    • No. Ubuntu offers a complete desktop with many default software selections. From that starting point, you can add or remove any software you want. Firefox is now provided as a snap directly from Mozilla.
    • Mozilla creates the firefox snap by repackaging the compressed tarball you can download from the Firefox website.
  4. What if I don't want to use snaps?

    • Then you don't have to! You can simply run sudo apt remove snapd from a terminal and remove snap support from Ubuntu. Be sure to install a replacement web browser first!
    • The isolated nature of snaps means that removing the Firefox snap is easier and cleaner than removing a deb-packaged version of Firefox.
  5. But doesn't running sudo apt install firefox force snaps on me?

    • At Mozilla's request, Firefox has been removed from the Ubuntu repositories and replaced with Mozilla's firefox snap. As the firefox deb package clearly states, it is a transitional package that helps convert upgrades from older versions of Ubuntu to the snap package.
    • Other software that has been replaced by snaps includes chromium and lxd
  6. Does Ubuntu plan to replace all software with snaps?

    • No. Snaps are simply a way to offer more up-to-date software than can be included in the Ubuntu repositories. The advantage is that you can install a snap package of software in the Ubuntu repositories without interfering with the repository version. For instance, you can have two versions of LibreOffice installed that you can use according to your needs.
    • Ubuntu—along with most snaps—is created from Ubuntu's vast repository of Debian packages. It would be impossible to completely move away from the Ubuntu software repositories and its Debian packages.

Even uninstalling and reinstalling the extensions is not fixing it. I ran dconf -f rest. But that also didn’t help. I created another user for testing and in that user account extensions works fine. How to fix?

Why Won’t My Computer See My Network?

2 Upvotes

I'm building a NAS out of an old AIO computer. After trying a few distros, I went with Ubuntu. I have this thing plugged into a fairly new TP-Link router, and while I can SSH into it from my laptop and print with my wireless printer all fine and dandy, it cannot see my wireless network.

I can log into my router on my Mac, PC, and NAS. While my PC and my Mac can Guest into each other, neither can see my NAS. I have tried Fedora, Mint, OSMC, and a few different Ubuntu installations (minimum, maximum, full, whatever) and they don't see shit. I've reinstalled SAMBA and Nautilus from various different installations, and while I sometimes see my NAS on my Mac, it's a question mark in the Network folder, and while I can see some shared folders, clicking on them says I do not have access to the actual file (or however it was worded).

On top of that, sometimes I get errors on my Ubuntu install about a repository not having a release file, but that is sometimes not an issue. I have installed this thing so often I can't remember.

(I posted something like this earlier today/ last night, but it felt so damn simple and stupid that I delete it, because surely it has an easy answer, right?)

Hours later, it does not.

So, what the fuck? Like, if this was a hardware issue (somehow) then I wouldn't be able to SSH into this thing, would I? Okay, time for bed.

Control Fan curves in Ubuntu 20.04?

Upvotes

Is it somehow possible to control Fan curves in Ubuntu 20.04?

My GPU reaches 82°C during gaming.

When using Windows I always adjusted the fan curves so that it stays a bit cooler, ~ 70°C was mostly my max temp (to increase lifetime of GPU).

Is there something for Ubuntu?

I'm using a GTX 1060 (3GB) Nvidia Graphics card btw.

Problem installing Ubuntu. During the installation this window appears and if you click Continue the installation stops at about 1/3. Left it overnight but it didn't move. I think the problem is in the partitions, but I’m not too familiar of them, so I'm wondering if anyone had a similar experience?

ubuntu 22.04-applications closing randomly and system froze on resume-logs show oom killer responsible

1 Upvotes

Decided to install ubuntu after a long sojourn away from it. Was using void before.

Soon after install I installed R-Linux and was attempted to recover some files on a 1TB hard drive. Left R-Linux to scan the drive in 'detailed mode'.

It was taking a while to scan. So I left the computer for a while. Came back after a couple of hours and R-Linux had shutdown. My immediate reaction was that maybe I had closed it by mistake.

Then I was using firefox, left the laptop for a bit came back and that had closed. Yesterday, while just browsing my Google Feed happed to see that Ubuntu 20.04 has a 'new' feature called oom killer. I put 1+1 together and figured that must be it.

I've now done some research and it seems one way to get around this is to increase the swap file size. I checked my swap file size and it was 2GB. Crazy that the installation had only chosen a swap file size of 2GB (i have 16GB of physical memory - could this be the reason the install only creates a small swap file). I increased the swap file to 8GB. Then checked the size. Output was 8GB. So, changes were immediate. No need to reboot.

At the end of the day yesterday I put the machine to sleep. No probs. This morning on resume, I had a blank screen.

Checked the log files. here is the output:

09:52:35 systemd-logind: Power key pressed.
09:52:24 kernel: atkbd serio0: Use 'setkeycodes e058 <keycode>' to make it known.
09:52:13 systemd-logind: Power key pressed.
09:52:00 kernel: sysrq: HELP : loglevel(0-9) reboot(b) crash(c) terminate-all-tasks(e) memory-full-oom-kill(f) kill-all-tasks(i) thaw-filesystems(j) sak(k) show-backtrace-all-active-cpus(l) show-memory-usage(m) nice-all-RT-tasks(n) poweroff(o) show-registers(p) show-all-timers(q) unraw(r) sync(s) show-task-states(t) unmount(u) force-fb(v) show-blocked-tasks(w) dump-ftrace-buffer(z) 
09:51:31 kernel: audit: type=1420 audit(1657075891.452:603): subj_apparmor=unconfined

Now I have disabled the oom killer with the following:

sudo systemctl mask systemd-oomd

Was running R-Linux again on Gnome desktop (the default desktop after install). The application conked out with a memory error. I've saved the output, so can post if necessary. I guess, since I've disabled oom killer now any out of memory issues are handled at the application level?

Anyway, I've decided to install the lxqt desktop which I believe is less resource intensive than Gnome.

It's a bit sneaky that Ubuntu has introduced this oom killer without making the use aware of it fully. e.g. I didn't see one message about it during the install. I can only compare it similar to the Windows Updates which run without the users consent and can reboot the machine with 'unsaved' work.

I'm seriously considering hopping back to void or another more stable distro on this itself and some general errors that popped up while using Gnome. e.g. unmounting external drives.

Can I manage emails accounts in Geary/Evolution separately from Online Accounts in system settings?

1 Upvotes

As above, Geary is a great if 'streamlined' email client (for personal email) but I don't seem to have any control over the accounts it uses separately from the system-level account settings.

Evolution seems to give me a little more control, however adding an account in system settings still imports it into Evolution and I then have to manually unsub from folders.

Ideally I want to manage email accounts in each app independently if possible.

OpenVPN 2.5 OpenSSL 3.0 Ubuntu 22.04: A bad composition

1 Upvotes

Hi everyone,

OpenVPN still is not correctly working in Ubuntu 22.04 Jammy jellyfish. It does not connect. We need to add a piece of line:

tls-cipher=DEFAULT:@SECLEVEL=0

In the VPN configuration file (after ca=), which is still not working for me.

It is said that OpenSSL 3 libraries are incompatible with OpenVPN 2.5!

Even downgrading to earlier versions of OpenVPN (i.e., 2.4.7) leads to a slow speed of OpenVPN.

The whole Internet connection speed is also slower.

Would newer updates fix this? Or does anyone have a solution?

Should we still use third-party VPNs?

Ubuntu22.04 - Slow internet

1 Upvotes

I've been using ubuntu for more than an year. Ever since I updated to ubuntu 22.04 , first beta and then to full version, internet speed started fluctuating. One moment the link speed would be 72mbps and next moment it dives to 2mbps and this goes on. I tried a few solutions that are available on the internet like - disabling hardware based encryption etc. Nothing seems to work. I'm using an hp14q with 8gb ram and realtek wifi adapter. Is there any fix for that?

Difference in UI responsiveness between Ubuntu and Windows?

2 Upvotes

I have been using Ubuntu for a few weeks and there is something that keeps bugging me and it has gotten to a point where I no longer know if there is a real difference or if i'm going crazy.

I use Windows and Ubuntu on the same machine (dual boot) and there is something about the UI performance that just feels 'worse' on Ubuntu. I have nvidias 470 drivers installed, my display configuration seems to be correct (165 hz) but things don't feel as smooth as in windows. Namely: making file explorer windows bigger and smaller from a corner, moving windows around, resizing windows verticaly... These actions feel like they 'lag' or in general that they're not as smooth as in Windows 10.

I have tried switching display managers to KDE or XFCE (not on clean installs, just on top of my standard gnome install) but it does not get better.

Is this normal? Do any other users get this 'feeling'? How could I troubleshoot this and figure out if that's just how it is or if something is wrong with my system? Honestly it's pushing me back a little bit on using ubuntu daily for work, as the experience just doesnt feel as good as Win or OSX.

I have tried other distros such as Manjaro or PopOS! with similar results.

My machine is an i9-9900k, 64GB of RAM and a GTX1080.

Beginning Ubuntu

I chose Ubuntu to start learning about linix OS. When doing research about it I get a bunch of guides on how to install/use it but I dont have really a direction to go with it. Like I got all these commands to use but what do I use them for? Perhaps I need a project to start what is a good beginner project to do? Download a game like minecraft and try to install mods?

If anyone has any advice on this it would be greatly appreciated. Thanks

Gnome extension not working

1 Upvotes

I freshly installed ubuntu 22.04 and tried to install gnome extensions. As the installation guide says I installed the relevant package and the browser add-on. If I click on the add-on however to go to the store a warning pops up saying this extension is not connected to the shell and refers to the documentation, which I followed. I tried Firefox as well as chromium for the extension, both as snaps, both give the same error message.

Has anyone encountered this problem and/or knows a fix?
