I have been trying to get Java for the past day now. I followed several tutorials but I keep getting the same error. After I put in
tar -xvf jre-7u4-linux-i586.tar.gz it says
Cannot open: No such file or directory
tar: Error is not recoverable: exiting now
I have a 64 bit system so I doubt that's the problem. The JDK installed perfectly, but I'm lost as to why the JRE wont work…
If OpenJDK isn't preferred, you can install the Oracle version from a ppa (which is a lot easier than manual installation, and you should also receive updates automatically). Adding via ppa also ensures that you are using the correct architecture (32 vs 64 bit).
