HOWTO

Yum

Exclude packages

In /etc/yum.conf:

exclude=package1 package2

Show installed packages

yum list installed

Show installed packages from epel

yum list installed | grep @epel

Show active repositories

yum repolist

or

yum repolist enabled

Disable repository

yum-config-manager --disable reponame

FAQ

Yum keeps trying Importing GPG key 0x51312F3F

yum clean all
yum makecache

Exclamationmarks?

Repository has expired metadata, try

yum clean expire-cache

What provides a certain file

yum whatprovides

Which package does a file belong to?

rpm -qf /bin/bash

Which packages depend on a package

rpm -q --whatrequires libX11

what files depend on package??

repoquery --requires --resolve <package>

Show dependencies for a package

yum deplist <packagename>

Installed package x.y.z (from anaconda) not available

Package not found on mirror

Check updates

yum check-update -q

Check security updates

HAHA GOTCHA! no security metadata on CentOS! There is for EPEL though. see https://access.redhat.com/solutions/10021 On CentOS 6 first install

yum install yum-plugin-security

yum list-security -q --errorlevel=0

Which repository is a package from?

repoquery <packagename>

or perhaps better

yum info packagename

Clear cache

yum clean all

or

yum clean all --enablerepo='*'

List files from package

rpm -ql packagename
dnf repoquery -l somepackage

Updateinfo file is not valid XML

remove yum-cron

Warning: RPMDB altered outside of yum.

Happens when you install something using rpm, what usually works is:

yum history sync

Not using downloaded remi/repomd.xml because it is older than what we have

Try

yum clean all

yum-daily

Yum error messages

YumRepo Error: All mirror URLs are not using ftp, http[s] or file.

Public key for *.rpm is not installed

Some stuff to try:

rpm --checksig -v /var/cache/yum/<channel-name>/packages/device-mapper-multipath-0.4.7-34.el5.x86_64.rpm
rm -rfv /var/cache/yum/* 
yum clean all

75 packages excluded due to repository priority protections

Try

yum list updates -d3

Error: rpmdb open failed

mkdir /tmp/rpm/
mv /var/lib/rpm/__db* /tmp/rpm
yum clean all

and then try again:

yum check-update

Multilib version problems found

Try

package-cleanup --cleandupes

Long version:

yum clean all 
yum list all --showduplicates

NOTE: this one takes forever!

yum check
yum list all --showduplicates

/var/tmp/rpm-tmp.y7ZaM4: line 1: fg: no job control

Try

rpm -e --noscripts <packagename>
