Kepret... setelah berkutat dengan versi 6 saya masih nggak yakin untuk meng-update versi 7 karena ya.. pakai netbook (panas kalau lama pakai linux) bagi anda yang ingin mengupdate selahkan pakai instruksi yang saya kopi paste :
The “Oracle-java″ package is no longer available in the official Ubuntu 11.10 Oneiric Ocelot and Precise Pangolin. In this post i will show you how to remove OpenJDK and install Oracle Java7 on Ubuntu 12.04 Precise Pangolin. First we need to remove the installed Open JDK Java: Now add the following PPA and install Oracle Java7: This work also on LinuxMint. Please let me know if this worked for you. Thankssudo apt-get purge openjdk*
