Can't uninstall

Ubuntu 20.04

Rebooted like in another issue. Didn't help. Because I cant uninstall, I cant install the new python 3.8 .deb file either someone posted. Catch 22 :/

```

Reproduce the failed apt removal on Ubuntu 20.04 and start with the Debian package's pre-removal script invoked by dpkg. Trace the service and autostart cleanup commands shown in the log; done means apt can remove automathemely without script errors and the package can be installed again.
