[Pkg-utopia-maintainers] Bug#838826: network-manager kills network on upgrade

[Juha Jäykkä]

Package: network-manager
Version: 1.4.0-4
Severity: serious
Justification: makes the system unusable

Dear Maintainer,

Upon upgrade to 1.4.0-4, network-manager disconnects network connections
and does not reconnect (as far as I can tell, it does not even try).

This is unacceptable as it makes remote management of systems impossible.

Serious because a remote system become completely unusable after this until
someone visits it physically (if one does not have suitable IPMI or something
similar in place).

This is also a regression from several years ago, when every upgrade and
restart on network-manager disconnected the network before reconnecting them
again. At least back then it managed to reconnect, so one only needed to run
upgrades in a screen (sensible precaution for remote upgrades anyway). Now
it does not reconnect, ever, so screen does not help.

Cheers,
Juha
