It looks like something specific to the Artix repos, community and extra are Arch Linux repos: Normal working situation: /var/lib/pacman/sync$ ls -lh total 12M -rw-r--r-- 1 root root 5.6M Jun  3 09:24 community.db -rw-r--r-- 1 root root 1.6M Jun  3 09:23 extra.db -rw-r--r-- 1 root root 1.7M Jun  2 20:51 galaxy.db -rw-r--r-- 1 root root 140K May 31 11:16 lib32.db -rw-r--r-- 1 root root 151K Jun  2 08:56 multilib.db -rw-r--r-- 1 root root 260K Jun  1 21:47 system.db -rw-r--r-- 1 root root  64K Jun  3 07:41 universe.db -rw-r--r-- 1 root root 1.8M Jun  2 19:59 world.db Faulty nonworking situation: /var/lib/pacman/sync$ ls -lh total 12M -rw-r--r-- 1 root root 5.6M Jun  3 09:24 community.db -rw-r--r-- 1 root root 1.6M Jun  3 09:23 extra.db -rw-r--r-- 1 root root 1.7M Jun  2 20:51 galaxy.db -rw-r--r-- 1 root root  114 Mar  1 08:11 galaxy.db.sig -rw-r--r-- 1 root root 140K May 31 11:16 lib32.db -rw-r--r-- 1 root root  114 Mar  1 08:11 lib32.db.sig -rw-r--r-- 1 root root 151K Jun  2 08:56 multilib.db -rw-r--r-- 1 root root 260K Jun  1 21:47 system.db -rw-r--r-- 1 root root  114 Mar  1 08:11 system.db.sig -rw-r--r-- 1 root root  64K Jun  3 07:41 universe.db -rw-r--r-- 1 root root 1.8M Jun  2 19:59 world.db -rw-r--r-- 1 root root  114 Mar  1 08:11 world.db.sig Also I can omit the pacman-key commands above to restore normal operation. Perhaps the db.sig things are obsolete and shouldn't be in the mirrors? But they don't seem to come from there anyway: https://ftp.cc.uoc.gr/mirrors/linux/artixlinux/galaxy/os/x86_64/ Or could it be that one of the Artix mirrors really has an old outdated os/i686 directory? I think there was some late 32 bit support after Arch had dropped it. Universe is a fairly new Artix repo and doesn't have a db.sig file in the error situation.
