Katoolin – Ubuntu Turned into Kali GNU/Linux Desktop

15.10katoolin

I installed Ubuntu 15.10 and after few days I installed Katoolin and now it shows Kali GNU/Linux Desktop and my Ubuntu Software Center is not working
even after removing Katoolin. So how to get back to Ubuntu 15.10 without having a fresh installation?

Best Answer

I had the same problem after installing Kali via Katoolin on Ubuntu 16.04 and it took me some time to figure out a solution. In my case Katoolin changed the settings in the lsb_release file.

I could fix it with running:

sudo -i gedit /etc/lsb-release

There I had to change the Kali settings, which do not belong there to:

For 16.04:

DISTRIB_ID=Ubuntu
DISTRIB_RELEASE=16.04
DISTRIB_CODENAME=xenial
DISTRIB_DESCRIPTION="Ubuntu Xenial Xerus"

In case you have another distro you need to adapt the names (see Wikipedia e.g.).

In your case:

DISTRIB_ID=Ubuntu
DISTRIB_RELEASE=15.10
DISTRIB_CODENAME=wily
DISTRIB_DESCRIPTION="Ubuntu Wily Werewolf"

For 17.04:

DISTRIB_ID=Ubuntu
DISTRIB_RELEASE=17.04
DISTRIB_CODENAME=zesty 
DISTRIB_DESCRIPTION="Ubuntu 17.04"

Then, run the following command to update grub:

sudo update-grub

After doing this everything worked fine again for me.

I hope this helps. Sorry, if the explanation is not perfect; it is my first answer here.
