I ran Lite Tweaks Package System Repair and I get a similar output after trying to update:

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

The incompatible App Grid software should be removed from the system.

After removing the software itself, ensure that the App Grid 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.

See this link for advice on selecting and installing PPAs
https://www.linuxliteos.com/manual/software.html#ppa

As you are on Linux Lite 7.x, ensure that any PPA you consider installing offers a version compatible with 'Noble'

Hey Steve,
Thanks so much for your reply. I'm new to this, so I don't know which piece of software I need to remove (I'm a real newbie). Can you tell from the error output which software is causing the problem, so I can remove it and the PPA?

A PPA (Personal Package Archive) is a personal repository that a software developer can use to distribute their software outside of the usual official repository system.  The error message posted arises because the system has had a PPA package called 'App Grid' added to it.  The App Grid software (I don't know what App Grid is or what it is supposed to do) is incompatible with the Linux version on the system so the Linux update/upgrade throws an error which stops the update/upgrade from working.

The links to the manual I posted explain PPA choice better than I do.

Adding a PPA is not a casual thing to do.  Did you specifically add 'App Grid' at some point ?  If not, then I guess it is possible that some other software installation added App Grid without your explicit knowledge - this would be a dubious practice unless it is documented.

What software have you added to your system since installing Linux Lite 7.x ?
What instructions did you follow for each instance ?
Something immediately prior to you starting to have update problems is most suspect.

Thank you again, Steve.
I don't know what software added the PPA, so I have decided to do the following:
- Reinstall the OS
- Use Timeshift before any software is added
- Keep a log of software added and if any PPA was required for it
- PAY CLOSER ATTENTION!

Thanks for being patient with a newbie like me, Steve
I am liking Linux, there is quite a learning curve for some of us though.

Peace!
