Can't update to 22.04 from 20.04

[rikitiki]

It seems I don't have some option or repository on my current system because I can't update it to actual stable version.

Command

lsb_release -a​

returns:

No LSB modules are available.
Distributor ID: Ubuntu
Description:    Ubuntu 20.04.6 LTS
Release:        20.04
Codename:       focal
​

When I try run

sudo apt full-upgrade
​

it returns

0 to upgrade, 0 to newly install, 0 to remove and 0 not to upgrade.
​

What I need to do?

[claydoh]

sudo apt full-upgrade

This only updates your system, not upgrading it to a new release, despite the wording used.

To fully upgrade, if you are not seeing a prompt, is to start the upgrade tool manually:

pkexec do-release-upgrade -m desktop -f DistUpgradeViewKDE

Thank you for the answering!

This command returns:

Could this be a side effect of the "phased updates" (https://www.kubuntuforums.net/forum/...e-ok-read-this)?

I can't remember if I have seen this in 20.04, though - but the solution in 22.04 or 22.10 would be to manually install the packages that have been held back with sudo apt install package_1 package_2 package_3 … and to release-upgrade like claydoh wrote afterwards.
Not sure about 20.04 as I said…

Probably not, as Apr in 20.04 didn't have this feature.



Before running apt full-upgrade, did you run sudo apt update to refresh the package list?

Does apt list --upgradeable show anything?

What third-party software sources, such as PPAs do you have, if any?

[rikitiki]

did you run sudo apt update to refresh the package list?

Yeah, sure I did it.

Thank you! I got ubuntu pro key and upgraded several packages. But still can't update the system.

sudo apt update

This one is easily fixable, there are hundreds of how-tos and posts on this type of error.
Here is one specific to your teamviewer one:
https://community.teamviewer.com/Eng...-not-available
This is the correct fix, you won't see any warning messages about things being deprecated on 20.04.
You can also disable the repo, or remove it as well.

Listing... Done libvkd3d1/jammy 1.3~jammy-1 amd64 [upgradable from: 1.1-4]
              lutris/focal,focal 0.5.12~ubuntu20.04.1 all [upgradable from: 0.5.10.1~ubuntu20.04.1]

You might try updating again, and see if that fixes things, and allows these to be installed/updated.
Try (re)installing these two, and see what the errors are.
If not, uninstall both of them. Whatever sources you added for these (winehq in particular) is probably conflicting with things, at least somewhat.

Now I don't have any warnings for apt update command:

You probably need to uninstall these 2 -- they are still marked as upgradeable.
I don't know why, or why they are not being updated, but these are not from stock, official Ubuntu sources.

You can reinstall them afterward.
Also, the upgrade process will disable all added PPAs and other addon sources. You will need to re-enable them afterward, but some may not have any software for 22.04 in them, which will cause errors, so it is best to check that they do offer packages for Jammy before doing so.

[rikitiki]

Thank you! It seems I successfully upgrade my system. I hope I won't have bugs

[claydoh]

I hope I won't have bugs

....but......Linux lol.




'
I didn't have any, but ymmv
upgrades can be a crapshoot. Mine have been fine, historically, but others won't even attmept one from their own personal experience.

[rikitiki]

It seems that I broke the system and now I can not use it. At first everything was great and all programs worked stably. I was excited because I really liked the new version of kde. However, I noticed that I do not have steam installed. And I just tried to install it through the console. sudo apt install steam. But this command, in addition to installing, began to remove programs one by one. and now I can't even login after reboot. how can this be explained? what am I supposed to do?

[rikitiki]

I can't even load the previous version. Omg...
