That should be apt-get full-upgrade.
`apt upgrade` is the equivalent of `apt-get upgrade`. It installs new
versions of existing packages but it will not add packages or
additional dependencies.
`apt full-upgrade` is the equivalent of the old `apt-get
dist-upgrade`. If a new version needs a new dependency or library or
something, it will do it.
Use `full-upgrade`. It does a more thorough job.
There is no point doing `autoremove` *before* installing new software.
Do it afterwards, if at all. It's not really necessary every time,
only if apt tells you obsolete packages are left.

Unplug and/or turn off the printer.
Remove *both* copies.
Reboot.
Try adding or auto-detecting the printer again.
