up2date -a libtool reported autoconf-2.13-5.noarch.rpm... The package autoconf-2.13-5 is not signed with a GPG signature. Aborting... RPM says [15:17:29] hubert:/hubert/home/ats $ rpm --checksig autoconf-2.13-5.noarch.rpm exec failed! Could not run pgp. Use --nopgp to skip PGP checks. Looks like it has a pgp but not a gpg signature, and up2date will complain without a GPG sig.
autoconf simply has not changed between 6.0 and 6.2 nor any updates for it have been issued, and 6.0 had pgp signed packages, so this really is not an autoconf bug. Perhaps up2date should not complain about this in the 6.2 version (in 7.0 and above all packages should have gpg signatures so only the 6.2 version could be changed). Reassigning to up2date.
