can't uninstall hplip

[Donald H Locker]

hplip (3.22.10) installed on 27 Jan 2023; this caused a number of other programs to fail (took a while to diagnose -- report from failing programs was consistentlly: "cryptography pkg 39.0.0 incompatible with pyOpenSSL 21.0.0"); finally traced to hplip installation.

FWIW, the last time I ran hp device manager (about two weeks ago) it worked fine; the only changes to the machine logged between then and now have been two automatic software updates. Ubuntu 22.0.4; System76 Gazelle17 uptodate on firmware and software.

Today, tried hplip-uninstall; error message: (uninstaller log stops at "Uninstaller log saved in:..."); hp-doctor fails same;

Purpose of uninstalling hplip is to try installing it in a python venv to isolate its python dependencies from the rest of the system.
