I was able to uninstall the CLI on WSL (Ubuntu 20.04.1 LTS on Windows 10 x86_64 host machine) using:
sudo rm -fr /opt/pf9/cli
sudo rm -fr ~/pf9
sudo rm /usr/bin/pf9ctl
but I am unable to uninstall pf-hostagent:
-bash: /home/jervan/pf9/bin/pf9-bash-profile.sh: No such file or directory
jervan@KORCLT38593:~$ ps -ef |grep hostAgent
