Comment 4 for bug 2008661

I run ubuntu 22.04.2 and I have the same problem, it sometimes pops up like every five minutes. I have tried to check manually using 'apt update' and once there was a problem with google-earth repo and the other time there were updates that were pending despite the updater showing no updates... You might want to check the command line updates for info...

Once 'apt update' is showing no updates the problem goes away ... temporarily, so far

Also some grub packages were held back, but I think they make no difference.
