After I've tried almost all your ISO download links I checked the link on the bottom of your site:
"KaOS users make torrent downloads available, see the forum for the different options."
MD5sum checked every time.
No difference, though.
One more odd thing after I made an USB boot installer, I guess on Mint - networks showed up BUT keyboard wasn't working. Just one time, so it looks like russian roulette on my particular system.
Checking now one more option to make a bootable pendrive (formatting it with bad sectors check, takes a looong time, I'll see what happens then).
