The version of Linux Lite being used is jammy based.  The webupd8 PPA software does not have a release compatible with jammy.  This conflict is causing the update process to error.

The incompatible webupd8 software should be removed from the system.

After removing the software itself, ensure that the webupd8 PPA reference is removed from the update list.
Removing the PPA reference from the update list should allow the update to run.

See
https://www.linuxliteos.com/manual/software.html#pparem

If using PPA software, it is important that the PPA has a release that is compatible with the OS in use.
