installing LibreWolf on a LM20 Live System

[bill99]

Hello forum,


Thank's fot the howto!

there quite a few howto install LibreWold on Linux Mint, but unfortunately they do not work on Live Systems (Mint ISO booted from USB-stick). Final error message: E: Unable to locate package librewolf.

Question:
What I am doing wrong?


Thank's in advance for your help!

Bill
