How do we download some from Ubuntu repo, as on Ubuntu e.g:
sudo add-apt-repository ppa:mkusb/ppa
or
sudo add-apt-repository universe
if effortless is only the first one it's fine, it's more prioritized.. thanks before
Nobody has packaged Ubuntu's mkusb for Arch/Artix. I'd recommend reading up on dd (https://wiki.archlinux.org/title/Dd). Alternatively, sometimes Etcher (https://etcher.balena.io/#download-etcher) works.
