Indeed, yes, I was confused.

@op: are you sure you understand the concepts this time, cause it looks like i already explained most of the things you're asking to you 3 days ago (well, the initial question was new, thus deseverved a new thread, but most of the additional questions you've asked were answered/explained before):

in my first reply in above topic, i even pointed to a more in-depth, beginner-level (simplified) post i made earlyer that should have explained some of the more basic concepts you still seem to struggle with:

It's not a problem if you don't get something, but it might be nice if you'd continue to ask questions in one topic untill you're completely sure you understand everything.
Setting up any kind of wallet can be dangerous if you don't completely understand what you're doing, especially setups like air gapped wallets or paper wallets.

As for the new quesion you asked (about updating your OS): i'd recommand NOT touching the internet with your airgapped device... Write the seed down, and when your OS becomes REALLY outdated, you can install a new version from an offline medium and restore your wallet using the seed (i'd use dd to clone the current OS to an offline medium before scratching it tough)

An extra tip i didn't give you before: check out the TESTnet... Do an airgapped setup using electrum on the testnet, fund it with testnet coins, spend the testnet coins, reinstall your os, restore electrum on the testnet using the previous seed phrase, play, learn, make mistakes (learn from your mistakes), repeat... Untill you're certain that you can fund, spend, transfer, scratch, restore,... without losing testnet coins. Only then move to the main net..
