[PLUG] I'm having trouble installing the Java Development Kit (JDK).

[Genaro Hernandez]

Hi everyone.

I'm contacting you because I'm trying to install the JDK on Ubuntu 14.04
but having trouble. I was hoping someone on the mailing list could help me.
So far, my online search has not been helpful.

I was following this video https://www.youtube.com/watch?v=LR_sDdZ0aOk, and
specifically the Ubuntu commands for installing the JDK. I was doing fine
until this command:

   - sudo update-alternatives --install "/usr/bin/javac" "javac"
   "/usr/local/java/jdk1.7.0_25/bin/ja­vac" 1

I updated that command for '1.7.0_80' since that is the JDK I am installing.

I'm attaching a text file with the Ubuntu commands I was following.

Thank you for your help!
