libc6 package breaks existing packages on air gapped server

Question

I'm running ubuntu 20.04 amd64 and trying to upgrade libc6 package on my air gapped server. I have my own apt repositories, where i store all the packages i download. I downloaded the latest version which is 2.37-7 and all of the latest dependencies, and when I try upgrading using sudo apt upgrade libc6, I get the error:

The following packages have unmet dependencies: libc-bin : Depends: libc6 (< 2.32) but 2.37-7 is to be installed libc6: Breaks: firefox (< 91~) but 82.0.2+build1-0ubuntu0.20.04.1 is to be installed Breaks: locales (< 2.37) but 2.31-0ubuntu9.1 is to be installed

I assume I need to download later versions of libc-bin, but this package is a bit sensetive, and I want to know if there is a safe way to do this, and also if there is a way to automatically download al the dependencies. Thank you!

Looks like you should have a fully local offline apt mirror, and not a set of package. Install apt-mirror on a connected machine, create a full mirror - and then use it on the air gapped machine.
