If you really need Oracle Java (some applications seem to insist on it) on Ubuntu here is the procedure using a PPA. sudo add-apt-repository ppa:webupd8team/java<br></br>sudo apt-get update<br></br>sudo apt-get install oracle-java7-installer HT to WebUpd8 http://ppa.webupd8.org/

UPDATE: [01-May-2012] It appears that this PPA repo is currently broken (does not allow to get GPG key and has unmet dependencies on x84_64). It appears that the install on i386 systems does work anyway if you ignore the GPG key error, but I wouldn’t install in that case as PPA installs are security risk enough without GPG errors. UPDATE: [11-May-2012] The reason the PPA does not work is that it has been disabled by Ubuntu due to a licensing issue with (not hard to guess) Oracle.
