[SOLVED] mystery of the disappearing network-manager

#1 Post by kau-92 »

Hello,

I recently wanted to configure a wifi network on my laptop, and I tried to find network manager / the GUI that usually lets me do this.
I can't find it anywhere. :( :(
and the little icon that was in the system tray of the bottom desktop panel has disappeared.

There is nothing relevant under the network section of settings.
Package manager shows that 'network-manager' package is installed. I reinstalled it but it didn't change anything.

I tried doing 'sudo service network-manager start' and 'sudo service network-manager restart' but it gives this error:

Failed to restart network-manager.service: Unit network-manager.service not found.

what should I do?

Hi,
You don't say what desktop you use but I guess you refer to the nm-applet.
To restart networking:

Code: Select all

user@debian:~$ su -
Password: 
root@debian:~# systemctl restart networking
Maybe you can restore it simply by typing nm-applet in the terminal and add it to start-up applications?

Code: Select all

$ apt search nm-applet
Sorting... Done
Full Text Search... Done
nm-tray/stable 0.4.3-2+b1 amd64
  Simple Network Manager frontend written in Qt

nm-tray-l10n/stable 0.4.3-2 all
  Language package for nm-tray
DebianStable

Code: Select all

$ vrms

No non-free or contrib packages installed on debian!  rms would be proud.

Desktop : I'm using KDE, Plasma.

doing : systemctl restart networking
does not bring up the network manager, though internet works fine.

apt search nm-applet
outputs exactly as the code in post above :

Code: Select all

Sorting... Done
Full Text Search... Done
nm-tray/stable 0.4.3-2+b1 amd64
  Simple Network Manager frontend written in Qt

nm-tray-l10n/stable 0.4.3-2 all
  Language package for nm-tray

typing nm-applet in the terminal outputs following :
bash: nm-applet: command not found

Then it's not nm-applet that you need but plasma-nm
and the restart command in Bullseye is:

Code: Select all

# service NetworkManager restart
See wiki.debian.org/NetworkManager for details.
DebianStable

Code: Select all

$ vrms

No non-free or contrib packages installed on debian!  rms would be proud.

Yes! plasma-nm was not installed for some reason. After install, connections show up under network section of settings.

thanks!
