Thank you for reporting this bug to Ubuntu.

Ubuntu 21.10 (impish) reached end-of-life on July 14, 2022.

See this document for currently supported Ubuntu releases:
https://wiki.ubuntu.com/Releases

Yes Ubuntu 21.10 is EOL, it was announced

The EOL means you need to modify your sources as is documented here - https://help.ubuntu.com/community/EOLUpgrades

Take note of the warnings about EOL, or note it in the initial release notes of the release, so you release-upgrade before EOL is reached.

I've marked this incomplete as it's an EOL release, and appears to be a support issue, also documented procedures for EOLUpgrades appears not to have been attempted.

I suspect a Support site would be more appropriate, eg. https://answers.launchpad.net/ubuntu. You can also find help with your problem in the support forum of your local Ubuntu community http://loco.ubuntu.com/ or asking at https://askubuntu.com or https://ubuntuforums.org, or for more support options please look at https://discourse.ubuntu.com/t/community-support/709
