I am still using 16.04. I plan on upgrading to 20.04 when the academic year is over.
I recently did something stupid and tried to install OpenPLC Editor, which involved uninstalling a bunch of things, including some Python and GTK stuff. Now, I can't connect to VPN. At first I couldn't connect to both my school's VPN and NordVPN, but I deleted and reinstalled the NordVPN connection, and it now works. My school's VPN connection does not work. Here are the instructions for getting on the school's VPN https://faculty-web.msoe.edu/hasker/resources/vpn.html
EDIT: Here is some more information:
1) I just upgraded to 18.04
2) Changing the password information to "Store the password for all users" got it to at least try.
3)
user@machine:~$ systemctl status network-manager

There appears to be some issue with ifupdown.
UPDATE: I just set up my server and took off the firewall exceptions for the desktop and tried to load NordVPN through OpenVPN, and it wan't load either now. I supposedly have NordVPN running on my desktop through the Nord Linux app, but I don't know how to verify that.
Any help is appreciated.
