cc @aaaskew Please test.

This is now tested and works, will merge to sort the bug and improve later.

This has worked for me in Ubuntu 24 but my old upgraded to Ubuntu 22 system did something weird.

I am not sure if this is due to network issues or what it downloaded but it appears it tried and failed to upgrade the sources.list (fortunately)

This is what I saw:

Hmm, maybe we should limit it to Ubuntu 24 then... Can you please try again?

Also, you have backups in etc/apt/ ;)

Tried again with Ubuntu 24 and 22 and it works for me with the re-test. I am assuming the error was due to a DNS or download failure that disappeared on retry. The sources.list did not actually get changed when that screenshot occured. The script just went a little mad. I assume it is due to some output being taken as what should be displayed in the dialog but that text is actually the script itself.

So consider the re-test ok for me.

Nice! Thanks for confirming. 👍
