Thank you! didn’t know about that command.

Edit: explicitly installing 10.1 with

sudo apt install wine-staging=10.1~focal-1 wine-staging-amd64=10.1~focal-1 wine-staging-i386:i386=10.1~focal-1 winehq-staging=10.1~focal-1

worked.

Thank you for the help!

But I can’t remove wine-staging, at least not via apt:

$ sudo apt remove wine-staging-i386

You might want to run 'apt --fix-broken install' to correct these.
The following packages have unmet dependencies.
 wine-staging : Depends: wine-staging-i386 (= 10.2~focal-2)
                Depends: wine-staging-amd64 (= 10.2~focal-2) but 10.2~focal-1 is to be installed
E: Unmet dependencies. Try 'apt --fix-broken install' with no packages (or specify a solution).

So no go there. --fix-broken doesn’t work either:

Any idea on how to remove Wine manually, bypassing apt?

The problem is that the whole apt system seems to be broken. It doesn’t let me install other packages, and I can’t even uninstall wine. So I wonder if any fixes from wine will work. It looks like this needs the user’s manual intervention.

but sudo apt --fix-broken install does not solve anything…
