After rebooting, NetworkManager all of the sudden has stopped working. Its icon appeared in the tray, then disappeared, then appeared again and so on 3-4 times.

All my config files are correct, I simply haven't changed anything.

I found this https://bugs.launchpad.net/ubuntu/+source/network-manager/+bug/1489154

However, it seems overcomplicated.

I have internet connection now, though, via wpa_supplicant.

So what do I do to fix it?

Is that your bug ? If so read the bug report

Please refer to comments #8 and #11. This is not a bug and has been closed.

The really mean comment #7 which give a detailed description of why this is "not a bug" and what to do to resolve the problem.

This isn't a bug -- we're blocking packages in wily-proposed specifically because they can be slightly broken, and the tests that failed and currently block promotion of the package are meant to do just that -- block things that may be a little buggy. From there, partial upgrades make things even worse, since you may be missing important part of underlying libraries.

and later ...

sudo apt-get install network-manager=0.9.10.0-4ubuntu23 \
    libnm0=0.9.10.0-4ubuntu23 libnm-glib4=0.9.10.0-4ubuntu23 \
    libnm-util2=0.9.10.0-4ubuntu23 \
    gir1.2-networkmanager-1.0=0.9.10.0-4ubuntu23

so, run 

sudo apt-get install network-manager=0.9.10.0-4ubuntu23 \
    libnm0=0.9.10.0-4ubuntu23 libnm-glib4=0.9.10.0-4ubuntu23 \
    libnm-util2=0.9.10.0-4ubuntu23 \
    gir1.2-networkmanager-1.0=0.9.10.0-4ubuntu23

If that does not fix your problem or that is not your bug you are barking up the wrong tree and we need more information.

  • And what will happen when I call apt update, upgrade next time? – Incerteza Mar 08 '16 at 12:08
  • I don't know, do you have the proposed repository enabled ? If so, disable it. You are asking me to guess without telling me about your system or even if this is your bug. – Panther Mar 08 '16 at 12:09
  • Whose bug can it be? – Incerteza Mar 08 '16 at 12:42
  • That bug was filed by https://launchpad.net/~laza74 . Are you having the same bug or are you just trying random solutions ? See http://askubuntu.com/questions/258616/how-can-i-debug-my-wireless-problem and https://help.ubuntu.com/community/WifiDocs/WirelessTroubleShootingGuide – Panther Mar 08 '16 at 12:48
  • I have the same bug. – Incerteza Mar 08 '16 at 13:58
  • so did you run the commands given to you in the bug report ? did that fix the problem ? did you disable the proposed repositories ? – Panther Mar 08 '16 at 14:00

  • So that is not really the same bug or same solution. Go through the links I gave you and update your question with the required information and you may need to file a new bug report. – Panther Mar 08 '16 at 14:14
