Why am I getting the terminal error "try apt-get -f install"?

  • 772

Okay, I just install Ubuntu (the LXDE version, which is Lubuntu) and everytime I try to install a package through the terminal with the "Apt-get install" command, this error pops up: 

E: Unmet dependencies. Try 'apt-get -f install' with no packages

And, yes this is for every package i try to install. When I do apt-get -f install this is the terminal output I receive:

Could someone please help me? I just started using linux 2 months ago, and switched to Lubuntu.

    Before anything, try

    sudo ldconfig

    Just to get that out of the way so we know it's not that.

    Then, try these commands, if you normally use sudo su then do not execute that command and do type sudo before every other command listed. If you normally typed sudo apt-get -f install, then execute these commands as listed.

    sudo su
apt-get update
apt-get autoremove
apt-get autoclean
apt-get upgrade

    And even if the last command fails try

    apt-get -f install

    For some reason using sudo su can be different than using sudo in terms of your $PATH.
