Public bug reported:
When I delete a connection from the Network Manager, nothing seems to
happen. If I attempt to delete it again, I get an error,
No such interface 'org.freedesktop.NetworkManager.Settings.Connection'
on object at path /org/freedesktop/NetworkManager/Settings/18
To reproduce, start by finding a connection that ends in "1" or "2".
It's unclear to me how these connections were created to begin with, but
they appear to be duplicates of existing connections - e.g. I create a
connection called "N5X" several months ago, and now I had "N5X 1" and
"N5X 2". Perhaps changing passwords triggered the creation of these
"duplicate" connections?
Anyway, when the first connection I tried to delete was not a duplicate
one, deletion went OK. When I started by trying to delete a duplicate
connection, and subsequent connection I tried to delete generated the
error above.
