By mistake I installed both server side and client side of Open-vpn and now I want to delete everything related to openvpn-server/client in my pc.
I already did.
$ sudo apt remove openvpn
$ sudo apt purge openvpn
$ sudo apt autoremove openvpn
But there are still these many files remaining.
$ sudo find / -type d -name "openvpn*" 2>/dev/null/
sys/fs/cgroup/devices/system.slice/openvpn-iptables.service
/sys/fs/cgroup/memory/system.slice/openvpn-iptables.service
/sys/fs/cgroup/pids/system.slice/openvpn-iptables.service
/sys/fs/cgroup/systemd/system.slice/system-openvpn\x2dserver.slice/openvpn-server@server.service
/sys/fs/cgroup/systemd/system.slice/openvpn-iptables.service
/sys/fs/cgroup/unified/system.slice/system-openvpn\x2dserver.slice/openvpn-server@server.service
/sys/fs/cgroup/unified/system.slice/openvpn-iptables.service
one thing to note is that these files do not show when I do locate openvpn after sudo updatedb. Then to remove them I tried to do.
$ sudo rm -rf $(sudo find / -type d -name "openvpn*" 2>/dev/null/)
$ sudo rm -r $(sudo find / -type d -name "openvpn*" 2>/dev/null/)
$ sudo rm -f $(sudo find / -type d -name "openvpn*" 2>/dev/null/)
But files still remain and this is the message they gave out.
