Gnome Network Manager GUI does not save routes

[Bartosz Woronicz]

As in the title. I enclosed the recording adding the route to the connection via GUI. Does not matter whether that is Ethernet, VPN. Fails everytime.

On the other hand adding via CLI works perfectly

mastier@drakkar:/etc/NetworkManager$ nmcli connection modify netplan-eno1 +ipv4.routes 123.123.123.123/32
mastier@drakkar:/etc/NetworkManager$ echo $?
0
mastier@drakkar:/etc/NetworkManager$ nmcli con show netplan-eno1|grep ipv4.routes
ipv4.routes: { ip = 123.123.123.123/32 }

Here's the screenshot after adding it via CLI

Status changed to 'Confirmed' because the bug affects multiple users.

[Jeff Lambert (jflambert)]

I'm affected as well, Ubuntu 22.04.2 and network-manager-gnome (1.24.0-1ubuntu3)

I also happen to use network-manager-openconnect-gnome (1.2.6-4) but I don't think it's relevant.

Thank you for providing the nmcli alternative (glad it accepts CIDR input compared to gnome-client)

Worth noting that it's not just adding routes that fails with the client. It actually erases all the routes if you make any other modifications and click Apply.
