Comment 5 for bug 2040153

The autopkgtest failures on arm64 are not related to these changes and it's happening for a while now. So they are not regressions.

I'm running network-manager from proposed on my main machine and the problem is resolved.

I was running 1.44.2-1ubuntu1.1 and upgraded to 1.44.2-1ubuntu1.2:

2023-10-25 09:52:16 upgrade network-manager:amd64 1.44.2-1ubuntu1.1 1.44.2-1ubuntu1.2

I tested it by simply removing a bunch of Network Manager connections from my system and checking all the YAML files were also removed.

It can be easily verified with a desktop VM in LXD:
 - Add a connection using the Network Manager GUI
- Remove the connection you just added
- Run netplan apply
- Check Network Manager again and observe the connection is back
- You'll see the following error in NetworkManager's journal: netplan_delete_connection: Cannot write output state: Read-only file system
- Upgrade network-manager from -proposed and run the same steps. All the deleted connection should result in deleted YAML files.
