Python dependency issue

Question

After trying to install python2.7.13 I have lost the ability to use my Ubuntu.

I have tried sudo apt-cache policy python2.7 python2.7-dev which gave me:

python2.7:
  Installed: 2.7.6-8ubuntu0.3
  Candidate: 2.7.6-8ubuntu0.3
  Version table:

        500 http: // ca.archive.ubuntu.com/ubuntu/ trusty/main amd64 Packages

and sudo apt-cache policy python:

python:
  Installed: 2.7.13-1
  Candidate: 2.7.13-1
  Version table:

     2.7.5-5ubuntu3 0
        500 http: // ca.archive.ubuntu.com/ubuntu/ trusty/main amd64 Packages

which are different versions... I tried apt-get -f install which gave me:

E: Error, pkgProblemResolver::Resolve generated breaks, this may be caused by held packages.
E: Unable to correct dependencies

and sudo apt-get install ubuntu-desktop gave me:

E: Unmet dependencies. Try 'apt-get -f install' with no packages (or specify a solution)

I have no idea what to do...

Answer 1

Try sudo apt-get install --fix-broken && sudo apt-get autoremove && sudo apt-get update.

Please let me know if this does not solve the problem for you.
