I'm newbie in Ubuntu. After dist-upgrade, system doesn't work correctly. GRUB background has been changed to Kali and in menu, Ubuntu has been replaced by Kali.

Terminal doesn't work either. On start-up, system reports many errors. Funny thing is that system identifies itself as Kali 2.

Ubuntu 15.10 + Xfce on ASUS K43BR (64-bit).

Help me please!

  • Sounds like you added a repo you shouldn't. Did you add the Kali repositories at some point, or make any changes to where your system gets its software? – Thomas Ward Jan 21 '16 at 15:02

    If you added Kali's "main" repo you basically screwed up your system. If you're an Ubuntu newbie, never do these things. Seriously. – Eduardo Cola Jan 21 '16 at 15:05
  • After problem I checked the repos and yes, "kali's main repo" was there. is there any way to remove effects by dist-upgrade? – Homan50 Jan 21 '16 at 15:10

    @Homan there's no way to undo it. You will have to reinstall your operating system to fix this. – Thomas Ward Jan 21 '16 at 15:59
  • Tnks bro, I should try a fresh install. – Homan50 Jan 21 '16 at 16:27

After a while looking around , I decided to do a fresh install but making backup of data is so boring! so i didn't do anything, grub works fine. theme is changed to Kali but core is fine. by using Ubuntu default desktop environment, I have removed Xfce and many extra packages installed before. then by cleaning up the system I installed them again. errors are gone and system works fine. the only problem is Software center which doesn't work at all. but don't worry, synaptic is here.

sudo apt-get clean
sudo apt-get autoclean
sudo apt-get update
sudo apt-get purge xfconf xfce4-utils xfwm4 xfce4-session xfdesktop4 exo-utils xfce4-panel xfce4-terminal  thunar
sudo apt-get autoremove
sudo apt-get -f install
sudo apt-get install xfce4
sudo apt-get install xfce4-goodies
