Comment 1 for bug 2010561

Hi Aaron, thank you very much for testing and spotting this "issue".
What you see is currently the "expected behavior", as described in https://netplan.readthedocs.io/en/latest/netplan-everywhere/#how-connections-are-managed-from-now-on

I.e. connection profiles not being imported into /etc/netplan by default (on installation), but only once (re-)created or modified through NetworkManager.

But maybe it's not the way that users would intuitively expect it to be and the NetworkManager package should automatically re-create and import all current connection profiles from /etc/NetworkManager/system-connections/ into /etc/netplan on installation time.
