Support for Ubuntu Ubuntu 20.10 (groovy) has ended more than two years ago and the package repositories have already been archived.

If you want to upgrade to a supported Ubuntu release, you must apply special workarounds.
See https://help.ubuntu.com/community/EOLUpgrades
If you need further guidance, don't hesitate to ask.

Another option is creating backup copies of your files to an external medium, doing a new installation of a supported Ubuntu release (e.g. 22.04 LTS) and then restoring your files from the backup.

Can you help with this problem?
