Wanted clean 4.1 install iso to USB. Qubes os cant open harddrive with downloaded QO, instructions need gnupg2, still error of keys fetching

  1. qubes os cant load harddrive- not showing in files when attached from QO
  2. cant fetch keys
    kubuntu@kubuntu:/media/kubuntu/Data/Qubes-R4.1.0-x86_64$ $ gpg2 --fetch-keys https://keys.qubes-os.org/keys/qubes-master-signing-key.asc
    $: command not found
    kubuntu@kubuntu:/media/kubuntu/Data/Qubes-R4.1.0-x86_64$ gpg2 --fetch-keys https://keys.qubes-os.org/keys/qubes-master-signing-key.asc

Command ‘gpg2’ not found, but can be installed with:
sudo apt install gnupg2
$ sudo apt install gnupg2

  1. error in fetching key
    $ gpg2 --fetch-keys https://keys.qubes-os.org/keys/qubes-master-signing-key.asc
    gpg: requesting key from ‘https://keys.qubes-os.org/keys/qubes-master-signing-key.asc
    gpg: WARNING: unable to fetch URI https://keys.qubes-os.org/keys/qubes-master-signing-key.asc: General error

Maybe try just gpg instead of gpg2. (They should be the same, but still.) I just did this in a Debian 10 qube:

user@disp2203:~$ gpg2 --fetch-keys https://keys.qubes-os.org/keys/qubes-master-signing-key.asc
bash: gpg2: command not found
user@disp2203:~$ gpg --fetch-keys https://keys.qubes-os.org/keys/qubes-master-signing-key.asc
