I think I spoke too soon. The sudo apt update process is working but when I try to do sudo apt upgrade I get an error:
mark@station-m2:~$ sudo apt upgrade

Seems that whatever update this is it is compressed with the zst format. I don't know if this is a repository error or something that needs fixing on my system.
Any help would be appreciated.
