This fix seems to be working generally. There's still a brief interruption of the network connectivity, while restarting the "snap.network-manager.networkmanager.service" daemon (obviously), but the SSH connection is recovered after a few seconds. I've built a core22 base snap, using https://launchpad.net/~slyon/+archive/ubuntu/lp1959570 and a UC22 image out of this to run this test (all executed over an SSH connection): |

This is to allow execution in constrained environments, like early boot or Ubuntu Core 20/22 where the PATH environment variable might not be set. E.g. for the 'nmcli' binary: It could be /usr/bin/nmcli for normal NetworkManager or /snap/bin/nmcli -> /snap/bin/network-manager.nmcli for NM snap
Also, consider /usr/bin/nmcli and /snap/bin/nmcli -> /snap/bin/network-manager.nmcli as valid implementations of 'nmcli', so it can be exected in a minimal environment, without the PATH variable being set (e.g. early boot or Ubuntu Core 20/22).

All tests green. I've re-built a package in the above-mentioned PPA + core22 base snap + UC22 image and run the reproducer from the bug report: Merging. |
