How to install Java?

It gives me a error message saying that I need to have permission. My account is unlocked so I assumed that would fix it but that did nothing. Perhaps there is a way to do this via the terminal where I could enter my password for things like this. I need the JDK to run minecraft so, yah, for someone like me this is pretty important.

  • You need to use ROOT permissions to modify usr/lib. If you gave some more information as to what you are doing exactly we might be able to help. Are you getting jdk7 from a PPA or what not.

Use repositories to install jdk7 - sudo apt-get install openjdk-7-jdk

You have to use root, either sudo or gksu

gksu nautilus

See https://help.ubuntu.com/community/RootSudo

and https://help.ubuntu.com/community/FilePermissions

So download the files, then transfer them

  • A bad idea - don't install software manually, especially in /usr/lib, as t may break other packages. Use repositories or /usr/local for experiments
