Question: I can't seem to be able to type in a password so that I may acquire access to #apt-get. I'm looking to update my system via terminal, but typing out my password does no good to get me into su, as the spaces stay blank, and what I know is the password won't go through. Has anyone else had this issue?

Answer: 
In order to set up the `Alt-Gr` key you must go to (setting -> keyboard -> layout settings -> keyboard settings -> then go to the typing tab -> press and hold the Alternative Keyboard Key setting -> move you mouse down to select the key you want to assign `Alt-Gr` to.

AltGr sounds like a lot of trouble for only a few symbols. A better choice might be the United States Alternative International keyboard. This one gives a choice of dozens of letters with diacritical marks . The k'bd is just like the standard k'bd except that the `~ ^' and the " are --dead-- keys ( delayed action ) until the next key is pressed. 
These are the accent grave, tilde, circumflex and the accent agut. Just these 5 added to all the vowels and many consonants gives dozens of extra characters . If you want to type the apostrophe by it self just hit the space bar. ( Or the quote sign ) I have Ubuntu 12.10 and it works OK. I used the instructions for Ubuntu 14.04 so I had to do some guessing but I finally got it to work.
