    If you don’t already have it, you’ll need the gpg keys:

    wget 'http://mirror.centos.org/centos/8-stream/BaseOS/x86_64/os/Packages/centos-gpg-keys-8-3.el8.noarch.rpm'
sudo rpm -i 'centos-gpg-keys-8-3.el8.noarch.rpm'

    Then it’s as simple as transitioning like so:

    dnf --disablerepo '*' --enablerepo=extras swap centos-linux-repos centos-stream-repos

    Don’t worry — it doesn’t remove any repos, it simply temporarily ignores all of yours, and downloads information regarding the new mirrors.

    You may at this point want to actually upgrade your packages:

    sudo dnf distro-sync

    You’ll now be able to use "yum" as usual.

    Try editing your dockerfile

    FROM centos

RUN cd /etc/yum.repos.d/
RUN sed -i 's/mirrorlist/#mirrorlist/g' /etc/yum.repos.d/CentOS-*
RUN sed -i 's|#baseurl=http://mirror.centos.org|baseurl=http://vault.centos.org|g' /etc/yum.repos.d/CentOS-*

RUN yum -y install java

CMD /bin/bash

    Refer to this code

    I tried to use CentOS 8 with wsl and got the same error. Steps to fix the problem (as root):

    # sed -i 's/mirrorlist/#mirrorlist/g' /etc/yum.repos.d/CentOS-*
# sed -i 's|#baseurl=http://mirror.centos.org|baseurl=http://vault.centos.org|g' /etc/yum.repos.d/CentOS-*
# dnf distro-sync
# dnf -y install java

    The top voted answer did not work for me (by @Hashbrown). The answer with Dockerfile was not for my case either.

    Go to /etc/yum.repos.d/ directory. Open .repo file and manually edit mirrorlist from $releasever to 8-stream.

    For example : /etc/yum.repos.d/CentOS-Linux-BaseOS.repo

    1. open file in vi

      sudo vi /etc/yum.repos.d/CentOS-Linux-BaseOS.repo

    2. comment mirrorlist=http://mirrorlist.centos.org/?release=$releasever&arch=$basearch&repo=BaseOS&infra=$infra

      #mirrorlist=http://......

    3. within vi, copy paste mirrorlist=http://...... line

      yy and p

    4. uncomment and edit the copied line by replacing $releasever to 8-stream

      mirrorlist=http://mirrorlist.centos.org/?release=8-stream&arch=$basearch&repo=BaseOS&infra=$infra

    5. save and exit vi

      :wq

    Repeat above 5-steps for other .repo files.

    Please follow the below-mentioned steps:

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

      cd /etc/yum.repos.d/

    2. Run the below commands to hash the mirror-list in all yum.repos.d files then replace the existed Baseurl with the vault.centos.org

      sed -i ‘s/mirrorlist/#mirrorlist/g’ /etc/yum.repos.d/CentOS-*
      sed -i ‘s|#baseurl=http://mirror.centos.org|baseurl=http://vault.centos.org|g’ /etc/yum.repos.d/CentOS-*

    3. Then run yum update or install any package you want

      yum update -y

    Use these commands to update centOS8.0 on AWS EC2:

    sudo sed -i -e "s|mirrorlist=|#mirrorlist=|g" 
    -e "s|#baseurl=http://mirror.centos.org|baseurl=http://vault.centos.org|g" 
        /etc/yum.repos.d/CentOS-*

    CentOS 8 reached EOL on 2021-12-31 (announcement).

    Therefore, the URLs to the mirrors don’t work anymore. Instead of using sed to modify the URLs to point to the archived mirrors, CentOS officially recommends to convert from CentOS Linux 8 to CentOS Stream 8 via:

    dnf --disablerepo '*' --enablerepo extras swap centos-linux-repos centos-stream-repos
dnf distro-sync

    After that, dnf/yum will work again.

    Update your docker file with below. It should work.

        RUN  sed -i 's/mirrorlist/#mirrorlist/g' /etc/yum.repos.d/CentOS-*
    RUN  sed -i 's|#baseurl=http://mirror.centos.org|baseurl=http://vault.centos.org|g' /etc/yum.repos.d/CentOS-*
    RUN yum update -y
