Apt-get non trova il pacchetto `git` su Ubuntu 12.04

Question

Sto cercando di installare git su Ubuntu 12.04. Ma quando inserisci il comando

sudo apt-get install git 

Ricevo il seguente messaggio. Ho già eseguito sudo apt-get update.

Package git is not available, but is referred to by another package. 
This may mean that the package is missing, has been obsoleted, or 
is only available from another source 
However the following packages replace it: 
    git-el 

E: Package 'git' has no installation candidate 

Answer 1

È necessario installare git-core invece

sudo apt-get -y install git-core
