Removing a package without dependencies

# rpm -e vsftpd-2.2.2-11.el6_4.1.i686 --nodeps

yum update or yum install fails with package conflict between 64 bit and 32 bit package architectures

yum install yum-utils

The package-cleanup --dupes lists all duplicate packages:

# package-cleanup --dupes 

The package-cleanup --cleandupes removes the duplicates (it asks for a confirmation to remove all duplicates unless the -y switch is given):

# package-cleanup --cleandupes   

Edit /etc/yum.conf, set the following line for Red Hat Enterprise Linux 5 and Red Hat Enterprise Linux 6:

exactarch=1

Edit /etc/yum.conf, set the following line for Red Hat Enterprise Linux 7:

exactarchlist=*

Run yum command:

# yum clean all

# yum update

yum error “Cannot retrieve metalink for repository: epel. Please verify its path and try again” updating ContextBroker

# yum --disablerepo=epel -y update  ca-certificates

# sudo sed -i "s/mirrorlist=https/mirrorlist=http/" /etc/yum.repos.d/epel.repo

vi /etc/yum.repos.d/epel.repo

go to line number 4 and change the url from

Enable CentOS CR (Continuous Release) Repository

# yum install xrdp --enablerepo=cr

# yum install centos-release-cr

# yum update 

# yum-config-manager --enable cr 

# yum repolist cr

[root@tswl ~]# vi /etc/yum.repos.d/CentOS-CR.repo

[cr]

gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-7

~                  ------------------------------------

You can then disable the cr repository (if you want) once CentOS 7.4 is out.

If you are on RHEL 7.4, you need to remove the temporary repository:

Error: Cannot retrieve metalink for repository: epel. Please verify its path and try again

update ca-certificates package. Before that just disable all repos with https that are failing

yum --disablerepo=epel -y update  ca-certificates        [BEST Commund]

# yum clean all; yum update --disablerepo=*rpmforge*

OR use command

vi /etc/yum.repos.d/epel.repo

go to line number 4 and change the url from

mirrorlist=https://mirrors.fedoraproject.org/metalink?repo=epel-6&arch=$basearch

to

mirrorlist=http://mirrors.fedoraproject.org/metalink?repo=epel-6&arch=$basearch

yum -y upgrade ca-certificates

yum -y upgrade ca-certificates --disablerepo=epel

Here it is how I managed to fix it:

Create these 3 following files:

Code:

Each of them with following content:

Code:

Then execute eg.

Code:

What wonders me:

I have quickly installed CentOS 5.9 on Virtual Machine to find out what should be mirrorlist.txt and it does not exist there.

The list I am showing in this post is taken form history, before I executed: yum clean all

What makes me more wonder is that following also does not work and gives value: Invalid release

Code:

CentOS 5.9 end of life : about a month ago

The main links are here http://vault.centos.org/5.11/

See http://mirror.centos.org/cent

Tried this one and it works

echo "http://vault.centos.org/5.11/os/x86_64/" > /var/cache/yum/base/mirrorlist.txt

centos 6

[root@localhost ~]#  yum update

#  vi /etc/yum.repos.d/CentOS-Base.repo

Change all

baseurl=http://mirror.centos.org/centos/$releasever/centosplus/$basearch/

to

baseurl=http://vault.centos.org/$releasever/centosplus/$basearch/

Resolution

To fix this problem you edit /etc/yum.repos.d/CentOS-Base.repo and replace all mirrorlist

1. Go to /etc/yum.repos.d/ directory:

# cd /etc/yum.repos.d/

2. Make copy of original file:

# cp CentOS-Base.repo CentOS-Base.repo.old

3. Open and edit file with any text editor:

# vi CentOS-Base.repo

4. Replace mirrorlist‘s

Replace sections:

With following:

5. Clean yum cache

# yum clean all

6. Run again yum update command:

# yum update
