I just succesfully installed texlive 2012, apart from the fact that tlmgr is missing: it should be in the directory /usr/local/texlive/2012/bin/i386-linux/ but there's not! The only thing with the name tlmgr is a link to a perl script! How could I solve the problem? I'm running Ubuntu, if it can help!
Thank you for the answers!
