I followed each of the non-optional steps in Architect. I opted to follow the suggested defaults for root and boot partitions and a swapfile. After editing pacman configuration and selecting a mirror near me, I choose yay+base devel and linux-latest. I’ve run this several times and chosen different DEs, including xfce, gnome, and kde. Each time the install ends in a basepkgs 255 error, and then dumps a lot of “package corrupted” and “invalid signature warnings”. As the installer quits it also spits out a message about segfaults in pacman.
What can I do to diagnose and correct this problem?
