I tried testing release LiveCD (antergos-2015.05.10-x86_64.iso), as 2015.04.12 is too buggy. Averything went smooth and fast, but after “checking integrity” I got error about cnchi can’t install packages and can’t continue. I tried about 5 times, even with reflector generated mirrorlist.
P.S. I’m writing from LiveCD: it’s the fastest LiveCD I’ve ever seen and the only one with pptp.
