Updates Issue Gimp PPA

[stevef]

The gimp PPA you are using doesn't (currently) have a release compatible with the version of Linux Lite you are using (jammy).  This error is stopping the update process from running.  To allow the update to run, you need to remove the PPA from the software list.  See the manual at the link below for information about how to check if a PPA has a suitable release and how to remove one that is causing a problem.
