Try this

If you have added a line from new ubuntu repository to /etc/apt/sources.list, erase the line. Then, run the commands

sudo apt-get update 
sudo apt-get upgrade

Answer 4

If you are facing problems regarding Broken packages then first of all remove that package by first checking dependencies and then forcefully remove that package, and don't ever forget to reboot when you do make enormous changes in your system. To remove that package use these shell commands

$ sudo su

Then Enter your password

# apt-cache rdepends package-name
# apt-get --purge remove --force package-name

Use these shell commands

# apt-get clean
# apt-get autoclean
# apt-get update
# apt-get upgrade
# apt-get dist-upgrade
# reboot

This worked for me, Try this, I believe this will fix all your problems, Good luck.

To list what you installed with aptitude type the following

xyz@sxyzcom~$ sudo apt-get remove

This should list what remains of your R install and possibly anything else missing dependencies Then you can run

xyz@sxyzcom~$ sudo apt-get autoremove

and that should get you back to square one.
