Segfault when attempting connection in Linux Mint Cinnamon 20 (0.9.3) #146

Closed DominicWatson closed 3 years ago

DominicWatson commented 3 years ago

On OpenFortiGui 0.9.3, when trying to connect to a VPN through the GUI, "nothing happens" - connection is not successful, there is no visible change in the UI to indicate "connecting" and there is no output in the VPN's log.

When trying to connect via the command line, I get:

$ sudo openfortigui --start-vpn --vpn-name MyVpnConnection
$ Segmentation fault

The following is the log from /var/log/syslog (I get the same when attempting connection through GUI + also commandline):

Looking further, I can see this is a duplicate of #99. Closing.

As mentioned in ticket #99, enabling the SUDO Preserve .env option fixed it for me. I enabled in the GUI with File -> Settings:
