can we do install everything from repo?

Question

can we do apt-get install * (install everything the repo has), if so, how many GB it would require?

Answer 1

The installation size depends on the content of /etc/apt/sources.list and the list files in /etc/apt/sources.list.d but would be about 680 GB.

And no, you can't install all packages via

sudo apt-get install *

Why? See below,.

But you could with this command, but you should not do that! Please. Ok?

Ok?! Can I trust you?

Ok.

aptitude -F %p search '!~i!~v' | xargs sudo apt-get install

If you start the command sudo apt-get install * in a terminal with bash you would see something like this (it depends of the content of your current folder).

$ sudo apt-get install *
