This question already has an answer here:
Permission denied when accessing su
1 answer
I'm trying to install Java, but it requires the "su" command.
When I enter my password, the password field remains blank.
I try to enter my password, but it remains blank. I press enter, just in case in the sight chance it's techincally entered and I can't see it.
It gives me an Authentication Failed message and it makes me enter my password again. Finally, I just exit the terminal. I've read this question
and did not answer my question. My instructions are here.And maybe I'm using the wrong version of Java, so if that is, please point me to the correct version. Here's my system stats:
I'm using terminal, on Ubuntu 14.04 LTS.
Also, I installed Ubuntu about 4 hours ago, so I'm new.
Any help would be greatly appricated.
Thanks in advance,
Ryan

su(without an explicit username) would require the password to therootaccount - which is normally disabled on Ubuntu. I'd suggest modifying the instructions so that you usesudoinstead.

No it does not. It needs "sudo".
but it remains blank
What did you expect? Inputting passwords is always going to be hidden so nobody behind you can see what you insert.
Regarding the link in your question: please do NOT use installers for operating systems other than Ubuntu (or Debian). Installers for Redhat or SUSE do NOT WORK on Ubuntu.
Regarding installing Java: before the command you are suppose to use to install java you put the command sudo and when asked for a password you insert the password for your user. If you have more than 1 user make sure you use the admin account; by default that is the user Ubuntu was installed with unless you changed it afterwards.
The default repositories have a JDK. Install can be done with:
sudo apt update
sudo apt upgrade
sudo apt install default-jdk
And for latest version from oracle you could use this how-to.

What java installer am I to use, then? And also, when my password is entered, it's not in dots or asterisks, it's just invisible and as good as a blank password.

Passwords are not echoed back to the terminal, so shoulder-surfers can't get the length. While it looks like a blank password, it is NOT. It's what you typed.
