Unable to update to Ubuntu 22.04 from Ubuntu 20.04

Question

So I've been trying to update to Ubuntu 22.04 development release but certain errors are coming. Whenever I try to update the following error comes ->

abc@ubuntu:~$ update-manager -d

    with open(dist_fname) as dist_file:
FileNotFoundError: [Errno 2] No such file or directory: '/tmp/ubuntu-release-upgrader-6ylluso8/Ubuntu.info'

Is there any solution to this? I guess a file named Ubuntu.info is missing.

EDIT: I was asked to disable 3rd party repos by @vanadium, but the results remained unchanged.

Just ran into this while doing a do-release-upgrade manually. The gui was failing before this. The workaround answer from here by MarianD is what solved it for me. You need to create the Ubuntu.info file in the /tmp/ubuntu-release-upgrader-*/ folder using touch.

for example: touch /tmp/ubuntu-release-upgrader-93aizvle/Ubuntu.info

This can be tricky since it makes a new folder every time you run do-distribution-upgrade and it can fail before you have a chance to type in the touch command for the newly created folder. Exciting! Took me 4 tries. Remember to capitalize the 'U'.

I have a strong feeling adding a PopOS repo to my system is to blame. I did it to get a non-snap version of Chromium but all hell broke loose as a result. I tried to undo the damage but two years later I still run across some scars. I see a reference to Pop.info in many of the answers to this problem.

Perhaps you meant do-release-upgrade? – user535733 Aug 13 '22 at 15:44 — user535733, Aug 13 '22 at 15:44

Just was surfing through internet and found the solution to this problem, and my Ubuntu 20.04 was successfully upgraded to 22.04. The solution can be found here.

Instead of a file called “Pop.info”(as given in the answer) make a file called “Ubuntu.info”

This is awfully close to a link-only answer. Can you (without stepping on anyone's IP) include some additional details of the fix? – Zeiss Ikon Apr 25 '22 at 19:06
You have 'pop.info' because you're on PopOS. PopOS is NOT Ubuntu and not supported here. (Closed as offtopic) – Thomas Ward Apr 25 '22 at 20:18
@ZeissIkon I mean i guess there is nothing much more to it, just a file named ubuntu.info was missing from the folder which I added during the update process – Krrish Dhaneja Apr 26 '22 at 02:10
@ThomasWard The answer he found was for PopOS, but Krrish has Ubuntu. He's just trying to make an unsupported upgrade. – Zeiss Ikon Apr 26 '22 at 11:08
Pop OS just annoying installed itself with a complete BS "Partial Upgrade" suggestions. Following the above two answers managed to at least upgrade me to the newest Ubuntu version - but with much frustration and gnashing of teeth to get things to how they were before this unwanted jig down the upgrade paths. – Fluffeh Jul 31 '23 at 09:41
