Permission denied

[prince]

Hey all. I've been using Sparky as a fast Windows alternative for some of my older machines, and I'm pretty impressed with the performance so far, aside from some of the weird quirks that pop up using dark themes (but that's a different question). I'm by no means a programmer or computer expert, especially when it comes to Linux, so the solution to this is probably really simple and I'm just a moron. I seem to be having trouble trying to install things from the terminal, it keeps telling me "permission denied". I swear there used to be a little program called APTuS or something that looked like a software repository or something, but I cant seem to find it anymore.

Thanks for your help and patience.

(I'd put the screenshot of the exact problem but I have no idea how. forums are hard)

You do not say which version of Sparky you are on.  There is #5 - stable and #6 rolling     If you are newer, especially with machines over a year old, #5 is the way to go. 

If you are into linux for the reasonable future, learning how to cut and paste from terminal to message field is helpful.

How to Cut, Copy, and Paste in the Terminal

In most applications Cut, Copy and Paste are Ctrl + X, Ctrl + C and Ctrl+V respectively.
In the Terminal, Ctrl+C is the cancel command. Use these in the terminal instead:
To cut Ctrl + Shift + X.
To copy Ctrl + Shift + C.
To paste Ctrl + Shift + V.

Note:  I have been working with the mentally challenged almost 30 years after leaving the laboratory, I would be grateful if you did not use the  "moron"  term.  You are de-valueing yourself and others. 

To use sudo for updating and upgrading  "sudo apt update" will update your program base of possible programs.  It will ask you for your password (not the root password) . 
                                                                      "sudo apt upgrade"    (or "sudo apt full-upgrade" in Sparky6) will allow you to upgrade all existing programs. 

Others can discuss the state of aptus. 

posting the output of "inxi -br"  give us some info on your machine and your repostories.
