Sustav za upravljanje paketima na Ubuntuu čini iznimno jednostavnim instaliranjem i uklanjanjem paketa, ali ponekad je važno utvrditi koju verziju određenog paketa koji ste zapravo instalirali.
Apt-get komunalije su jednostavno front-end uslužni program debian dpkg, koji zapravo radi pravi posao. Pomoću tog uslužnog programa možete odrediti koja je verzija instalirana.
dpkg -s
Evo primjera, gdje sam pokušavao otkriti koja verzija Ruby sam instalirala na moj sustav:
geek@ubuntuServ:~$ dpkg -s ruby1.8
