[Pkg-utopia-maintainers] Bug#939294: network-manager: After upgrade to 1.20.0-1, mac address of wlan0 is randomized

[Jörn Heissler]

Package: network-manager
Version: 1.20.0-1
Severity: important


Hello,
I upgraded several packages, including network-manager (1.18.0-3 -> 1.20.0-1).
During the upgrade, my wifi connection disconnected and wouldn't connect again.
Luckily I wasn't doing the upgrade from remote ;-)

It appears that the mac address of my wlan0 device is now changed and my
wifi router refused the new address because it got a whitelist.

There is no mention of this behaviour change in the docs and it's
unclear how to disable/control this feature.

I suggest that this change is reverted or at least users should be made
aware of it. And users should be pointed at relevant documentation.

In fact I'm not sure that network-manager is the culprit, but it's a
likely candidate.

Thanks
Jörn Heissler
