I have a problem. Since I upgraded my Ubuntu 12.04 to 13.04, I've been receiving lots of errors, I can't install any program because it shows me a message that says (for this example I'll try to install Synaptic):

>alexis@McLovin:~$ sudo apt-get install synaptic

I'm new in Ubuntu, I hope it's not a dumb question. Thank you(English is not my native language).

This question has been asked before and already has an answer. If those answers do not fully address your question, please ask a new question.


Try running these commands:

sudo dpkg --configure -a
sudo apt-get install -f
sudo apt-get update
sudo apt-get upgrade
sudo apt-get dist-upgrade

Or the one-liner:

sudo sh -c "dpkg --configure -a && apt-get install -f && apt-get update && apt-get upgrade && apt-get dist-upgrade"

just one line worked for me ..

sudo apt-get install -f 

also .. i keep doing the following for no reason .. they might have been a factor in the solution

sudo apt-get update
sudo apt-get upgrade

ps: the "install -f" removed skype from my system
