    How to set the JAVA_HOME variable?

    • achmiral

      1. Find the java path using this command
      $sudo update-alternatives –config java

      2. Copy the path from your preferred installation and then open /etc/environment using nano or your favorite text editor
      $sudo nano /etc/environment

      3. At the end of this file, add the following line, making sure to replace the highlighted path with your own copied path.
      JAVA_HOME=”put the java path here”

      4. Save and exit the file, and reload it.
      $source /etc/environment

      5. Test
      $echo $JAVA_HOME

        any idea on how to uninstall this?

        • Cyprian Guerra

          I understand this is an old question but /etc/environment is just a file that is sourced (meaning it’s source code is loaded) each time your system boots, so all you need is to remove the line you used to set the JAVA_HOME variable and on your next reboot JAVA_HOME variable won’t be set (or overwritten, whatever you were doing) by /etc/environment. If it is still set, something else is doing this, not your /etc/environment file (check your $HOME files: .profile, .bashrc, .zshrc… I don’t know how java installation loads on your system, some init file might’ve come with a package).

    I am getting this problem on the 2nd step.

    E: Could not get lock /var/lib/dpkg/lock – open (11: Resource temporarily unavailable)
    E: Unable to lock the administration directory (/var/lib/dpkg/), is another process using it?

    • Niks

      You’re probably running another command that users apt-get…maybe installing some other software in another terminal or updating your system…
      First let that complete and then try the above commands one by one…

  • Venki Ravi

  • Ethan
