How to check Debian/Ubuntu Linux package version using apt-get/aptitude command

Posted on in Categories , , last updated March 16, 2016

I am a new Debian / Ubuntu Linux sysadmin. I would like to find out what version I would install if I ran the apt-get command. How do I find out which versions of a package can I install using apt-cache/apt-get command? How do you check package version using apt-get/aptitude on Debian or Ubuntu Linux server?
