Powered up my new Pi-B 1'st time yesterday. I expected to enter UID (pi) and P/W (raspberry) and then startx. That never happened. Booted right up to a GUI.
Figured since I ordered with a pre-installed raspian 8GB SD card ... it came configured to behave that way. As I am 'learning' the environment, I come across a few things which ask me for a p/w ... such as "Aptitude Package Manager Text" and depending on what I want to do, such as Become root ... raspberry is rejected. Happens whenever I am challenged for a p/w. Where do I go from there ... what is amiss? Thank you in advance.
The Aptitude program does ask you for the actual root password however the root password is not set by default. Instead of starting Aptitude from the menu, start it in a terminal session with:
sudo aptitude
Then all options will work.
-OR-
You could set a root password with this command:
sudo passwd root
You will be asked to enter a password 2 x. Note this not the same password as the login but could be set to the same text.
After doing this you can start Aptitude from the menu and enter the root password when it asks you...... Do you want to become root?
Finally Aptitude is kind of cumbersome to use. I prefer to use Synaptic Package Manager...... You can download and install with:
sudo apt-get install synaptic
Note Synaptic is a GUI program only ...... Aptitude can be run from a console session with or without the GUI loaded.
Edit: Synaptic asks for the pi login user and password not root.
Unless specified otherwise my response is based on the latest and fully updated RPiOS Buster w/ Desktop OS.
