Cannot remove pf9-hostagent on WSL

[BioGeek]

I'm using WSL1

$ cat /proc/version
Linux version 4.4.0-18362-Microsoft (Microsoft@Microsoft.com) (gcc version 5.4.0 (GCC) ) #1049-Microsoft Thu Aug 14 12:01:00 PST 2020

I had previously installed pf9, but wanted to uninstall it. I did:

rm -rf ~/pf9 
rm -rf /usr/bin/pf9ctl
rm -rf /opt/pf9

In hindsight, I probably shouldn't have done that last line, because now when I try to install something via apt-get, I get the error:

$ sudo apt-get install python3-distutils
Reading package lists... Done

python3-distutils is already the newest version (3.8.5-1~20.04.1).

And when I try to force uninstall pf9-hostagent, I get:

So, how do I get rid of pf9-hostagent? This is now blocking me of installing anything else.
