I’ve attempted many tries at installing Antergos with the Cnchi installer 0.12.1, from the 2015.08.18 and 2015.09.09 ISOs.
I use LVM for my /home partition. (I’ve done this on every distro from Fedora, OpenSuse, Manjaro, Ubuntu (various flavors), Linux Mint and Elementary OS with no problems.)
From running Cnchi in terminal I noticed right after the Advanced Installer process and install summary confirmation when the actual install starts the installer removes my LV and the VG then it tries to mount and install the home files to the LVM. Which of course since it just removed the LV and VG, so it’s no longer there.
Once the installation is finished it either reports an error associated to a bad command string or it actually finishes. The problem now after the initial boot my /home folder is now associated to the /root partition and my entire LVM is disabled.
After much searching the only thing I could find on this issue was from March of this year that was supposedly fixed. But as it stands it does not look like it has been fixed.
