Hello,

Anytime when I issue rpm command, there will be a warning massage “warning: only V3 signatures can be verified, skipping V4 signature”.

For example,

[root@hadoop-datanode44 ~]# rpm -qa | grep -i post

postgresql-server-8.3.8-1PGDG.rhel4

warning: only V3 signatures can be verified, skipping V4 signature

postgresql-8.3.8-1PGDG.rhel4

postgresql-pgpool-II-2.3.1-1

postgresql-libs-8.3.8-1PGDG.rhel4

postgresql-devel-8.3.8-1PGDG.rhel4

What does this message mean? Thanks.
