software updater gives an error message and stops

Thank you for taking the time to report this issue and helping to make Ubuntu better.

Have you fiddled with any apt configuration files, or done anything that would fiddle with them like adding PPAs, installing software from third-party sources, etc.?

Thank you for your help.

December 2021 I did install zuluCrypt version 6.0 from their website.
In March 2020 installed FAudio and Wine.
Apologies for my slow response as I look at my notes and try to find
anything that may help.
Install on the Surface Pro was a challenge but the system has been
trouble free except in November last there was an issue with apt
(https://github.com/linux-surface/linux-surface/issues/625) and I made
the changes discussed there which including adding ppa:tj/bugfixes.

There is no error shown, everything seems to be in a sane status.
What do you now get for the command

sudo apt full-upgrade
