Bug ID: 507770
Summary: Ethernet connection unable to connect at boot when
using "Auto connect to VPN" with WireGuard VPN config
Classification: Plasma
Product: plasmashell
Version First 6.4.3
Reported In:
Platform: Arch Linux
OS: Linux
Status: REPORTED
Severity: major
Priority: NOR
Component: Networking in general
Assignee: [email protected]
Reporter: [email protected]
Target Milestone: 1.0
SUMMARY
When you have a WireGuard connection in the "WiFi & Networks" panel of KDE and
select your Ethernet to automatically connect to that WireGuard VPN, upon next
reboot, the Ethernet connection can't connect to the network at all, meanwhile
the WireGuard connection already seems to be established (which should be
impossible if the Ethernet hasn't established the connection yet). The only way
to solve this is by manually disconnect from the WireGuard VPN first, then edit
the Ethernet, uncheck the "Auto connect to VPN" checkbox and apply the
settings. After that the Ethernet adapter will immediately work again and
connect to the network. This only affects WireGuard VPNs. OpenVPN configs work
without issues.
I can only test this with Ethernet. I do not know if this affects wireless
adapter aswell, because I don't have WiFi.
STEPS TO REPRODUCE
1. Open the settings and go to "WiFi & Networks"
2. Have a WireGuard VPN configuration in your "WiFi & Networks" settings panel
3. Select your Ethernet adapter, go to "General" and check "Auto connect with
VPN" and select the WireGuard VPN
4. Reboot
5. Your computer will now have trouble connecting to your network
6. Open the settings and go to "WiFi & Networks" again
7. Disconnect from the WireGuard VPN first
8. Uncheck "Auto connect with VPN" and click apply
9. Your Ethernet will now connect to your network without issues
OBSERVED RESULT
Ethernet connection stops working on "Auto connect with VPN" for WireGuard VPN
configs after reboot
EXPECTED RESULT
Ethernet should connect without any issues, just like with OpenVPN
