Problem in installation of GIMP 2.8 and removing pre-installed GIMP 2.6

Question

I have installed gimp 2.6 and without removing it I installed gimp 2.8. Now both are not working and when I run an update it is showing the link broken. It suggested to install apt-get install -f. But it is not getting installed. I am unable to remove the installed gimp from Ubuntu Software Centre. I need help.

Answer 1

Use these commands in the Terminal (one command at a time)>>

sudo apt-get clean 
sudo apt-get autoremove 
sudo apt-get update 
sudo apt-get upgrade 
sudo apt-get -f install
