Yum-plugin-priorities
This page is intended to explore the possible use of yum-plugin-priorities in order to help prevent the installation of unwanted rpms from 3rd-party repositories such as dag, dries, etc.
Installation
yum --enablerepo=extras install yum-plugin-priorities
On SME Server 8.x use (untested!)
yum --enablerepo=extras install yum-priorities
Configuration
The installation of yum-plugin-priorities will create /etc/yum/pluginconf.d/priorities.conf with the following settings
[main] enabled = 1 check_obsoletes = 1
These settings tell yum to pay attention to the 'priority' setting for each repo, and to make sure the 'obsoletes' flag in a low priority repo will not result in the removal of a package from a higher-priority repo.
If you are not running SME Server 7.4, update smeserver-yum
yum update smeserver-yum
modify yum template
cp the original and add the following to the bottom of the fragment
nano -w /etc/e-smith/templates-custom/etc/yum.smerepos.d/sme-base.repo/20repositories
if (exists $props{priority})
{
$OUT .= "priority" . '=' . $props{priority} . "\n";
}
DB values
Use this script to create DB priority values
#!/bin/bash for REPO in smeaddons smecontribs smedev smeextras smeos smetest smeupdates smeupdates-testing addons base centosplus contrib extras updates do db yum_repositories setprop $REPO priority 10 #set to 99 for testing when you want to remove priority done signal-event yum-modify
Usage
- If you install any contribs or non-sme packages using any form of --enablerepo=<xxx>, update with the following to make sure you get any available updates for your extra packages
yum update --enablerepo=<xxx> --enablerepo=<xxx2>
- If you get a missing dependency error from yum
- re-run yum manually using --exclude <pkgname> on the command line, replacing <pkgname> with the package that is preventing your update
- If you suspect that the blocked update resolves a security issue, you must decide for yourself whether to compromise the original SME Server/CentOS package and force the update of the non-SME Server/CentOS package by running
yum update --enablerepo=<xxx> --enablerepo=<xxx2> --noplugins <pkgname>
