I’m sure you were thinking I was tell you: install Debian!…but no, this time I’m going to be more condescend thus I’m going to give you a tip. After installing Ubuntu one thing you can do to feel you are using Debian is open a terminal and type this:
sudo apt-get install aptitude sudo aptitude update
Now you will be using the Debian’s default console package management .
But what are the differences between aptitude and apt-get / apt-cache?
That doubt was already commented on this article aptitude vs. apt-get
User password vs. root password
Another thing you can do is to assign a password to root
sudo passwd root
After this you can log in as root and forget about sudo, in addition you will separating the installing user from the real system administrator role.
