Upgrade to 21.10 : failed to fetch apt URIs to fetch

[mmstick]

You can use the refresh os option from the installer. 21.10 is EOL since July so Ubuntu took the repositories offline.

Alternatively, you can try updating the sources lists in /etc/apt/sources.list.d/ to 22.04 (set all of the codenames to jammy) and updating manually with sudo apt update and sudo apt full-upgrade after that.

The output of apt policy pop-desktop pop-session chrome-gnome-shell gdm3 gnome-shell pop-default-settings may show why you're currently encountering the error message in your issue description.

We do have code that partially handles old-releases URLs for EOL'd versions of Ubuntu (e.g. here and here), but looking at this section of the code, that may only take effect if the current release is EOL, not the next release.

thanks for your replies.
I have tried the jacob's solution but still issues with the broken packages. (full-upgrade does not work).
the "apt policy " command generates the below report. the installed & candidate versions are identical.

I have edited your comment to put the output in a code block. Please place three backticks (```) and a line break before and after output when you post.

[edd5913]

thanks. I didn't aware of it.

[jacobgkau]

I have tried the jacob's solution

Your output does not show that you applied the configuration change that I suggested properly. You still have hirsute sources, not jammy. Also, you are missing the Pop!_OS release repository source (that is why you're getting the apt error message.)

If you want to recover the current system, you need to access /etc/apt/sources.list and the files in /etc/apt/sources.list.d/ and change all instances of old-releases.ubuntu.com/ubuntu to apt.pop-os.org/ubuntu, change all instances of hirsute to jammy, and you also need to add the Pop!_OS repository (apt.pop-os.org/release) to the system. For the final step, you should have a file at /etc/apt/sources.list.d/pop-os-release.sources containing the following text:

X-Repolib-Name: Pop_OS Release Sources
Enabled: yes
Types: deb deb-src
URIs: http://apt.pop-os.org/release
Suites: jammy
Components: main

Running sudo apt update should show no errors and should only say jammy (not hirsute anywhere.) Only after that is the case, you can try the sudo apt full-upgrade again.

I would recommend creating a Pop!_OS USB live disk (or verifying that your Recovery partition is working, if you have one) before attempting this. Doing a Refresh Install from the installer like Michael suggested would be your escape valve if something else goes wrong during this process.

I think you are right a fresh install is the best choice before loosing everything.
thanks for your support.

[jacobgkau]

A Refresh Install is not a "fresh" install. Refresh keeps your home directory.

I'm going to go ahead and close this issue since we haven't heard back from a while (also because upgrading to an EOL release seems to be out of scope right now.) If you still need assistance, please reach out on Mattermost: https://chat.pop-os.org/pop-os/channels/upgrade-help
