The official documentation can be found here.

When using Centos 6, I cannot run 'yum update' anymore, I get this error 'Cannot find a valid baseurl for repo: base'

When using VirtualBox with a Centos6 image I cannot do yum udpate anymore, I have checked on the internet and it looks that Centos6 is deprecated.

[root@centos69 ~]# yum makecache
Failed to set locale, defaulting to C

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

    There could be two possible solutions to solve this issue:

    1. Edit the CentOS-Base.repo file with vim
    vim /etc/yum.repos.d/CentOS-Base.repo

    Delete or comment every line that starts with 'mirrorlist'.

    And add the following line to every [section] of the file like [base], [updates]...

    baseurl=https://vault.centos.org/6.10/os/$basearch/
    1. Another solution could be running this command on an image that comes from this repo https://vault.centos.org/
    /scripts/autorepair centos6_base_repo_is_no_more

    Yes, like red hat 6.x centos 6 did go EOL in november 2020, hope you don’t have anything sensitive stuff in that vm.

    You can change to use the vault at vault.centos.org. First you should disable any repo that no longer work. You can get a list of repos with

    yum repolist

    then you can disable them with

    yum-config-manager --disable  {reponame} {reponame}

    like

    yum-config-manager --disable  base update

    or just disable all of them

    yum-config-manager |grep ^\[|tr -d ']['|xargs yum-config-manager --disable

    Once the broken repos are disabled you need to add the vault repo.

    yum-config-manager --add-repo=https://vault.centos.org/6.10/os/x86_64/

    After that you can install packages as needed but remember – it’s no updates to anything so if security is a concern you need to change os to something newer that is supported.
