I just spent a few hours removing some extra error messages from pkg_add e.g.,
$ doas pkg_add screen-- will just say: http://ftp.fr.openbsd.org/pub/OpenBSD/6.0/packages/amd64/screen-4.0.3p6.tgz: unsigned package (signify(1) doesn't see old-style signatures) instead of the previous much longer diagnostic... or: $ PKG_PATH=http://ftp.fr.openbsd.org/ doas pkg_add screen-- http://ftp.fr.openbsd.org/: empty Can't find screen-- (still two lines, because there could be several paths to look at)
