I have Ubuntu 12.04LTS 64 bit installed parallel to Windows 7 on my laptop. Installing skype on Ubuntu, I installed some dependencies of skype, and it removed almost all of my packages installed on laptop. Good thing now is, skype installed, but nothing else remained. After the installation completed, the desktop disappeared. I believe my ubuntu-desktop uninstalled. The software center disappered too, so did python. While the internet was still working, I installed firefox, vlc and nautilus. Then I stupidly restarted the pc.
I cannot access the internet from ubuntu now(do not know how). As the desktop is gone, I can only login commandline, with no packages! I tried opening vlc, firefox and nautilus, each of these asks for display options.
Is it possible to restore to the default package settings without losing any data?
