I have a LXC container which is connected to a remote VPN using OpenVPN.
After upgrading to buster, the VPN does not start anymore.
I'm using Debian buster on my host OS and Debian buster on the guest OS.
Both were updated from stretch. Aside from OpenVPN there's only deluged
and deluge-web that are installed.
This is the journalctl log for the openvpn service:
root@dl:/# journalctl -u openvpn-client@pia.service

I've searched online but I haven't found anything relevant to my situation.
Anything to help me figure this one out will be greatly appreciated. Thanks!
