No matter how many articles have i found and read about installing and using Cockpit on Ubuntu, but I am no able to manage Networking and Updates in same time. While I want to manage network, I must have NetworkManager service up and running, otherwise i can see just blank white sceen in Network tab. But while NetworkManager service is up and running, I am not able to manage updates (receiving "Cannot refresh cache whilst offline" error message). Does anyone has solution for this strange behaviour, please?
