Topgrade v9.0.1 can't find apt_pkg

johnblommers commented 2 years ago

What did you expect to happen?

topgrade should update from the APT repository. It used to until the other day.

What actually happened?

It uses nala instead of apt because it is installed, and nala throws this error. Make sure nala is installed properly, or remove it if you don't mean to use it. See 1e259269995405192dd24cb2ad1d6210fc927403 for reasoning.

Removing nala restored Topgrade's ability to update APT-based packages.

I don't remember installing nala but as they say "memory is the first thing to go."

All good now. Thank you.
