After solving my problem by downgrading perl-NetAddr-IP to the CentOS repo's version, yum is of course telling me perl-NetAddr-IP is out of date and needs to be updated (back to the buggy one in RepoForge). So looks like yum-priorities is in order (ha! the pun!), but I have a question >> Hmm, OK, prioritze CentOS repo over RepoForge then will yum update >> figure out the rest? I don't see any priority settings in my yum conf >> files... > > # yum list | grep priorities > yum-priorities.noarch 1.1.16-16.el5.centos installed > > # cat /etc/yum/pluginconf.d/priorities.conf > [main] > enabled = 1 > check_obsoletes=1 > > Then add "priority=n" to the repos sections. > n=1 for CentOS > n=2 for repo 2 > etc... If I already have a bunch of packages from RepoForge, some of which might also be in the CentOS repo (some presumably with lower version numbers), what happens after installing and configuring yum-priorities? Do those packages automatically get downgraded? Does yum complain and tell me I should downgrade? I assume upgrades would happen per usual if there are newer versions of packages in CentOS repo. I'm slightly concerned because I have a handful of packages that got installed automatically from RepoForge when I installed amavisd-new from there, and I'd hate to break something. Thanks for any preemptive advice!!!!
