Error on 'apt update' on Ubuntu 20.10 (Groovy)

[Jon Cline]

I'm getting this error when trying to refresh my repos:

E: The repository 'http://ppa.launchpad.net/alexlarsson/flatpak/ubuntu groovy Release' does not have a Release file.
N: Updating from such a repository can't be done securely, and is therefore disabled by default.

This blocks me from updating the repo of other apps which makes this a security issue.

Thx

Thanks for taking the time to report this bug and helping to make Ubuntu better. We appreciate the difficulties you are facing, but this appears to be a "regular" (non-security) bug. I have unmarked it as a security issue since this bug does not show evidence of allowing attackers to cross privilege boundaries nor directly cause loss of data/privacy. Please feel free to report any other bugs you may find.
