Hi ei-admin,
Please make sure that you do have internet connection.
Looks like CentOS 6 has reached End of Life (EOL) in November 30, 2020.
YUM might be attempting connect to deprecated repositories.
So, we need update deprecated repositories URL’s and point to the vault.

Resolution

Code: Select all

To fix this problem you edit /etc/yum.repos.d/CentOS-Base.repo and comment out mirrorlist and replace baseurl with:
baseurl=http://vault.centos.org/6.10/os/$basearch

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

Code: Select all

# cd /etc/yum.repos.d/

2. Make copy of original file:

Code: Select all

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

3. Open and edit file with any text editor:

Code: Select all

# vi CentOS-Base.repo

4. After editing it should looks like:

Code: Select all

[base]
name=CentOS-$releasever - Base
#mirrorlist=http://mirrorlist.centos.org/?release=$releasever&arch=$basearch&repo=os&infra=$infra
baseurl=http://vault.centos.org/6.10/os/$basearch

[updates]
name=CentOS-$releasever - Updates
#mirrorlist=http://mirrorlist.centos.org/?release=$releasever&arch=$basearch&repo=updates&infra=$infra
baseurl=http://vault.centos.org/6.10/updates/$basearch/

[extras]
name=CentOS-$releasever - Extras
#mirrorlist=http://mirrorlist.centos.org/?release=$releasever&arch=$basearch&repo=extras&infra=$infra
baseurl=http://vault.centos.org/6.10/extras/$basearch/

[centosplus]
name=CentOS-$releasever - Plus
#mirrorlist=http://mirrorlist.centos.org/?release=$releasever&arch=$basearch&repo=centosplus&infra=$infra
baseurl=http://vault.centos.org/6.10/centosplus/$basearch/

5. Clean yum cache

Code: Select all

# yum clean all

6. Run again yum update command:

Code: Select all

# yum update

Also, please consider update your system from CentOS 6 to CentOS 7 or 8.

Best Regards,
Vinh

Hi ei-admin,
Please try edit the file named /etc/yum/pluginconf.d/fastestmirror.conf , run:

Hi ei-admin,
My teammate has suggest the followings:

Code: Select all

The errors are caused by Centos removing the Centos6 versions of the repositories and moving them to the vault.
What the customer need to do is to permanently disable the "base", "updates" and the "extras" repo's under the "/etc/yum.repos.d/CentOS-Base.repo" by editing the file and setting "enabled=0".

Then they need to edit the  "CentOS-Vault.repo" file and enable the base and updates section and that will remove the errors as the system will be pointing to servers that still exist.

Also, old cached of "mirrorlist.txt" files must be deleted as well:
/var/cache/yum/x86_64/6/base/mirrorlist.txt
/var/cache/yum/x86_64/6/updates/mirrorlist.txt
/var/cache/yum/x86_64/6/extras/mirrorlist.txt

Hope this helps.

I think we've almost got it!

Hi ei-admin,
You are getting the 404 error because those URL's mirrors were not available (supported) anymore for CentOS 6x.

We want to disable everything inside the "CentOS-Base.repo" and start using the "CentOS-Vault.repo" file for CentOS 6x.

From the list provided in your last reply, looks like not everything in the "CentOS-Base.repo" file were disabled.
I am only seeing "[centosplus]" and "[contrib]" sections were disabled.
We also want the "[Base]", "[Updates]" and "[Extras]" (sections) ALL to be disabled as well.

Code: Select all

Please edit the "CentOS-Base.repo" file again and add "enabled=0" to the "[Base]", "[Updates]" and "[Extras]" sections  ....  Each section must have the "enable=0" set ....  or you can just rename the "CentOS-Base.repo" file to "CentOS-Base.repo.notUse".

Now, start using the "CentOS-Vault.repo":

Code: Select all

Please make sure you set "enabled=1" to ALL the sections inside the "CentOS-Vault.repo" file.

Code: Select all

# yum clean all
# yum update

Hope this helps!!
