How to make a Live .ISO bootable distro USB on QubesOS
I have a (offline) Vault app Qube (debian-12-xfce) which i use only for my USB drives/files which has never been online and i have downloaded LMint .ISO to another App Qube which i do use online then i Moved it to my offline Vault USB app Qube where the .ISO file sits inside a attached USB drive and i have tried right clicking the ISO to try and make it bootable to the other USB drive attached to the same vault app Qube yet theres no option like there is on other Linux distros to simply make the ISO bootable so i tried to do the dd command which i saw on Qubes forum but this one not work for me either so i tried xfburn application but that never worked so i tried to find the repo for etcher so i could download it to a template and thus put it on the vault app qube all offline but i no find that.
I have also tried on the offline template things like;
sudo apt install etcher
sudo apt install ETCHER
sudo apt install Etcher
On QubesOS is there an easy way to create live bootable USB with a distro such as Linux Mint please as my other Laptop has an issue and i can not diagnose its issue without having a Live bootable distro to plug into it and im kinda desperate as the other laptop is normally what i use as a fall back plan where i can do everything on it which i cannot do on QubesOS as im a Qubes beginner you see.
