I have a PPA installed which does NOT have a release file for my 21.04 system. Currently, the outdated PPA is stalling anything else from updating. I would like to keep the PPA enabled, but have all other updates and upgrades pass through. Is this possible?
EDIT: 'upup' is just an alias for "sudo apt update && sudo apt upgrade"


sudo apt update; sudo apt upgrade-;instead of&&so that whenapt updatefails it still runsapt upgrade. – muru Aug 06 '21 at 09:12
