Known Issues & their Fixes

Issue

Cannot install any Cockpit add-ons or perform any updates from the UI after installing Cockpit

             

If you're here because you're on Cockpit running on Ubuntu 22.04.1 LTS and you can't get the Cockpit Updates functionality to work, here's the answer to get it working.

Step1: Create the file /etc/NetworkManager/conf.d/10-globally-managed-devices.conf Contents of 10-globally-managed-devices.conf ->

[keyfile]
unmanaged-devices=none

Step2: Create the fake interface by running the following command

nmcli con add type dummy con-name fake ifname fake0 ip4 1.2.3.4/24 gw4 1.2.3.1

Step3: reboot, and cockpit updates work perfectly.
