Why isn't it taking my password?
 

I have read the similar threads but they didn't help much. I am trying to install Java and it asks me to type su in terminal and then enter my root password, I do this and it says it faild to verify my password. So I tried to open my home folder and it simply said "Permission Denied".


I am running on Ubuntu and the other threads only mention Lilo or something like that. The only thing I can think is the problem is that my dad got on and changed the log in session but I don't know what the default was before he got on and he did set the new one as defualt and I guesse it just dosn't allow me to use password proteced files. What should I do?

ubuntu does not have a root password, so you can't enter it. instead run "sudo sh ./java.whatever.bin" to do it ubuntu stylee.

then again though, you should just install via apt anyway, no need to worry about all this downloading stuff...

"sudo apt-get install sun-java6-jdk" for the full jdk. personally my needs are covered using the icedtea-java7-jre package.
