The Error
When cockpit is installed on Ubuntu Server 19, we might get following errors
Cockpit Cannot refresh cache whilst offline
Cannot refresh cache whilst offline
The Fix
By disabling the network-manager, we can resolve those errors (Yes, It’s more of workaround rather than fix)
Warning: Do not run these commands on production server, unless you know what you are doing.
1 Disable network-manager service and stop it immediately, then restart the system
sudo systemctl disable network-manager.service sudo systemctl stop network-manager.service sudo reboot
2 Now, get back to cockpit, errors won’t be there anymore
