After the 7.1 update syspatch -c started throwing errors due to a missing signatures file:
Patch check: syspatch: Error retrieving http://ftp.openbsd.org/pub/OpenBSD/syspatch/7.1/amd64/SHA256.sig: 404 Not Found The error is valid. To suppress this message it would make sense to drop an empty place holder SHA256.sig file whenever a new release comes out. --lyndon
