Yesterday (21 Oct 2014) my development machine said it had to be restarted due to an update. After rebooting and logging in I got no desktop manager. There happened to be an open konsole.

After trying a bunch of things I started muon and found that my KDE workspace is broken.

The problem is that I can't start the networking as I cant get to the network manager applet. Then I hit Ctrl-Alt-F2 and open a command line session and found that ifup doesn't work due to networkmanager settings. But I can't find the config files.

So how do I start the network from the commandline? What are the commands to get the KDE workspace package re-installed?

I assume that accessing the network enables you to re-install the needed packages, so maybe that fixes your problem.

First, disable network-manager for the running session:

sudo service network-manager stop

Next, try to bring up your network ethernet device (wlan is much more complicated on command line) and fire a dhcp client:

sudo ifup eth0
sudo dhclient eth0

If everything works fine you might have an address now and can reinstall everything you need via:

sudo apt-get install --reinstall kde-workspace lightdm-kde-greeter

  • I disagree. The title fits the description. The workspace doesn't come up and the network doesn't either. Fixing the workspace is his priority. It's unclear if he needs internet access to fix his workspace. – MadMike Oct 23 '14 at 6:30
  • Hm... I give you that the main priority is to get the workspace running, but the core problem right now seems to be the network as far as I see it... let's see what brings the solution. – liquidat Oct 23 '14 at 8:29
  • It is the core problem in your answer because your fix needs network access. – MadMike Oct 23 '14 at 8:38
  • Yes, didn't his question mention that he has network access, but the network configuration is not correct? I assumed that might help. If I am on the wrong track, I'm sorry that I tried. – liquidat Oct 23 '14 at 11:29
  • Don't be sorry. I think your answer is okay. It's too bad we didn't receive any feedback of it yet. My disagreement is only about your first sentence about requestiong to change the title of OP.
