This question already has an answer here:
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 >Reading package lists... Done >Building dependency tree >Reading state information... Done >Some packages could not be installed. This may mean that you have >requested an impossible situation or if you are using the unstable >distribution that some required packages have not yet been created >or been moved out of Incoming. >The following information may help to resolve the situation: > >The following packages have unmet dependencies: > synaptic : Depends: libept1.4.12 (>= 1.0.9) but it is not installable > Recommends: rarian-compat but it is not installable >E: Unable to correct problems, you have held broken packages.
I'm new in Ubuntu, I hope it's not a dumb question. Thank you(English is not my native language).
