On my laptop the screen resolution stays at VGA's 640x480 after upgrading from 21.04 to 22.04. I tried to install further updates in Discover (hoping that this would resolve the issue) but when I click Install there the pwd dialog appears for fractions of a second and then there's:

Discover - Update_Issue

I found Screen resolution stuck at 640x480 after upgrade but if I try to use Xdiagnose I get this in Discover:

Discover - Xdiagnose

and nothing happens no matter how often I click Install.

UPDATE

Any ideas how to restore my apps and settings I lost (as described in my answer herein)?

    Ubuntu 21.10 (along with all flavors) is End-of-Life and thus unsupported on this site (https://askubuntu.com/help/on-topic), and many other Ubuntu sites, unless your question is specific to moving to a supported release of Ubuntu. https://fridge.ubuntu.com/2022/07/19/ubuntu-21-10-impish-indri-end-of-life-reached-on-july-14-2022/ https://help.ubuntu.com/community/EOLUpgrades – guiverc Sep 05 '22 at 22:53
  • @guiverc Well, "Issue upgrading 21.04 to 22.04 ... You need to upgrade to 21.10 first." and this 21.10 was the version that was taken automatically when I performed sudo do-release-upgrade -p. I want to upgrade to 22.04 in the end. – Gerold Broser Sep 05 '22 at 23:21
  • The meta-file will show 21.10 is EOL & thus the upgrade path for ubuntu-release-upgrader won't upgrade to 21.10 anyway.. If it's a desktop, I'd recommend an upgrade via re-install ; I keep systems of all supported releases & when 21.04 reached EOL, I didn't need 21.10 as already had one so my 21.04 was used as a QA-test install of non-destructive install & became kinetic or 22.10 with my manually installed packages auto-reinstalled, music & user files untouched... It's also faster than release-upgrade or hacks. – guiverc Sep 05 '22 at 23:26
  • @guiverc Great that you had what you had and that worked what you did. I don't have that and this doesn't help me in any way. By upgrade via re-install you mean purging this installation and perform a completely new one with the latest 22.04? Seriously? – Gerold Broser Sep 05 '22 at 23:44

    @GeroldBroser no, if you run the installer without formatting your disk, it will install the new version while leaving all your files and applications alone. That is what is meant by "upgrade via re-install." – Esther Sep 06 '22 at 02:21

    Upgrade via re-install is something I call it; older Ubuntu (desktop) used to call it Repair installation and it's likely returning as an option on the canary installed but doesn't work there yet last time I used it, but I've described it 30+ times on this site (often in comment) or in answers too. Lubuntu call it install using existing partition (see here though intended for QA testers) but it's re-use of existing partitions without format! which triggers the repair/re-install. – guiverc Sep 06 '22 at 03:50

    The real intent was to repair an installation; ie. same release, but works fine in upgrading... It copes with Ubuntu repository software, isn't intended to cope with 3rd part software (in QA only Ubuntu repository software is used!) which makes it less useful for many end-users but they'll usually upgrade before EOL anyway. It's also not intended for server apps (which can store config/conf files in system directories that are erased prior to install; thus configs are lost!) but server apps aren't used in desktop installs. – guiverc Sep 06 '22 at 03:53
  • "This question is off-topic, as it is specific to an unsupported release of Ubuntu."?!? 22.04 is a LTS: http://www.releases.ubuntu.com/ The first sentence of the Q reads: "[...] after upgrading from 21.04 to 22.04." – Gerold Broser Sep 19 '22 at 08:32

Got it. GRUB's default selection is still the first one: Ubuntu. If I select Ubuntu 21.10 a few items down the resolution matches the one of my screen.

(Really BIG) BUT all my system and app settings (e.g. Firefox settings and bookmarks) and all apps apart from the default are gone now there. That's really bad since I installed and configured a lot. Time for another AU question...or is there another way to bring all that back?

UPDATE

I just realized that the first GRUB selection Ubuntu is already 22.04, so apparently two upgrades have been performed in one. I performed (still in 640x480):

$ sudo apt update
...
$ sudo apt upgrade
...
$ sudo dpkg --configure -a

(I was told by sudo apt upgrade to do the last manually.)

Restarted afterwards and the proper resolution and all settings/apps are back now!

There are, however, "No available connections" in the bottom panel network icon drop-up. Though there are 3 Wi-Fi in System Settings > Network > Connections. WT...H?!?

I connected an Ethernet cable, restarted Kubuntu, the network adapter's lights are on on the router but there's nothing about it in ... Network > Connections. WT...even more...H?!?

(I'm sorry having to say that this is one of the worst journeys I had when upgrading an OS since 40 years in IT. And it doesn't end here.)

Activated mobile hotspot on my cell phone, to no avail.

Connected my cell phone via USB, activated USB-tethering, to no avail.

There's one notification:

Network Management

Failed to get secrets for [...]_2.4G
No agents were available for this request.

[...]_2.4G is one of my WLANs.

UPDATE 2

Cont'd at "No available connections" after upgrading from 21.04 to 22.04.

UPDATE 3

I ended up with abandoning Ubuntu and installing openSUSE Tumbleweed. This means a few days of installing/configuring now but I don't have mercy with OSs that do not work as they did before after an upgrade. Fortunately with Linux there's always an alternative.
