Java console quit working! Proxmox 2.x and 3.x

Manual installation

This amounts to unpacking a downloaded archive file in a terminal window and executing the script. It has the advantage of being fast and the disadvantage of not properly ‘installing’ the script. On top of that, a possibly installed (out of date) sun-java6 installation will remain installed on your system, be it more or less invisible. If you choose this option, this is what you do:

• download the package using this link
• open your system’s download directory in a terminal
• unpack the package using the command
  sh update-sun-jre.bin
• execution of the script and installation of the Runtime Environment will follow automatically

Alternatively – e.g. if you want to take a look at the script first:

• download the package using this link
• open your system’s download directory in a terminal
• unpack the package using the command
  sh update-sun-jre.bin -x
• when you are ready, you can use the command
  sudo ./update-sun-jre -v install
  to install the Runtime Environment
