The CTAN won't give you the name of the Ubuntu package, which effectively was texlive-latex-extra
, because, the package resume
has been removed from Ubuntu (from Debian too, and even from TeXLive apparently) since lucid 10.04, as shown here: http://packages.ubuntu.com/search?suite=karmic&searchon=contents&keywords=res.cls
It seems that the package had a license compatibility problem, as explained here: http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=510749
