@Lukas Märdian: i have "noble" running (24.04). Might be this is the difference.
@João Ciconet: when exluding the "mpqemubr0" interface to be handled by NetworkManager via /etc/NetworkManager/conf.d/90-unmanage-devices.conf [keyfile] unmanaged-devices=interface-name:docker0;interface-name:br-*;interface-name:mpqemubr*;interface-name:lxcbr*;interface-name:lxdbr* then forticlient VPN is working. But imho this is kind of a workaround and not a good solution for a normal Linux-Desktop User. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to network-manager in Ubuntu. https://bugs.launchpad.net/bugs/2089930 Title: NetworManager crashes when modifing connection (ipv4.ignore-auto- routes yes) Status in Netplan: New Status in network-manager package in Ubuntu: Confirmed Bug description: When trying to connect with forticlient to an SSL-VPN, the connection will fail with "Config DNS failed" Then i was searching in logs of forticlient and found: 20241127 07:07:55.291 TZ=+0100 [sslvpn:EROR] nmtools:255 Command to set ipv4.ignore-auto-routes returned with status 256. 20241127 07:07:55.291 TZ=+0100 [sslvpn:EROR] nmtools:1060 Failed to modify connection mpqemubr0 property ipv4.ignore-auto-routes 20241127 07:07:55.291 TZ=+0100 [sslvpn:EROR] dns:1007 Failed to finish Network Manager configuration 20241127 07:07:55.291 TZ=+0100 [sslvpn:EROR] vpn_connection:2071 Config DNS failed Next i was searching what this means.
