Package: network-manager
Version: 1.36.2-1
Severity: important
Tags: upstream
X-Debbugs-Cc: [email protected]
I used to connect to a VPN using network-manager-l2tp and network-manager-l2tp-
gnome.
The connection recently stopped working (see log below). A connection is
established but terminates quickly after logging a series of "Received out of
order control packet" messages. Also the connection is not usable (no ping to a
machine in the vpn possible) in the short amount of time the connection is
present.
Downgrading the packages "libnm0" and "network-manager" to version 1.34.0-1
solves the problem and makes the VPN usable again.
A similar problem was described at

kodi-qt5-mozilla-networkmanager-pipewire/105493/53?page=3
A big shoutout to eggy and michaa7 in the German Debian forum who helped me
find a temporary solution for the problem:
