Controlled installation of Lean 4 on Debian/Ubuntu #

This document explains a more controlled installation procedure for Lean 4 and mathlib on Linux distributions derived from Debian (Debian itself, Ubuntu, LMDE,...). There is a quicker way described in the main install page but it requires more trust. Of course you can get even more details about what is going on by reading the bash script that will be downloaded below: elan_init.
