I have following output for /etc/environment, java_home is already installed there.

output of cat /etc/environment 

PATH="/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/u‌​sr/local/games" 
JAVA_HOME =/usr/lib/jvm/jdk1.7.0/bin

I have updated the language support and getting the below error

    I am not sure of how /etc/environment is applied by PAM, but it looks like it is sourced. So when it encounters a line like:

    JAVA_HOME =/usr/lib/jvm/jdk1.7.0/bin

    the shell will interpret JAVA_HOME as a command because of the space before =, which is a grave error since JAVA_HOME is not found in the PATH nor defined as an alias or function. An error in a source causes the shell to exit (since maintenance scripts are run that way), which is why this error stopped installations. (Equivalently, a space after = causes the shell to see /usr/lib/jvm/jdk1.7.0/bin as a command, which is not that bad, but still a problem.) So the correct line is:

    JAVA_HOME=/usr/lib/jvm/jdk1.7.0/bin

  2. I was facing the same problem for many months. I didn't give attention at first but it started troubling when I would download updates and they won't install. Finally, I found the solution. The problem was the path of JAVA_HOME. My path was: 

    JAVA_HOME = '/usr/lib/jvm/java-9-oracle'

    I replaced it with

    JAVA_HOME=/usr/lib/jvm/java-9-oracle

    So, basically I removed the quotes and the spaces.

    How to do it ?

    Check the PATH and JAVA_HOME path variables by using 

    $ cat /etc/environment

    It shows something like

    PATH="/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/local/games"
JAVA_HOME = '/usr/lib/jvm/java-9-oracle'

    I suggest you to take a back up of the original environment variable in .orig using

    sudo cp /etc/environment /etc/environment.orig

    use sudo nano command to forcefully change the variable path

    sudo nano -w /etc/environment

    After editing the path by removing quotes and spaces use Ctrl+X to exit, press Y to confirm and rename the new file.

    and check the path again.

     $ cat /etc/environment

    Now update and upgrade your system for smooth performance and installations.
