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!
