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

You don't need the `cd` command. Even if it's there it's inconsequential. Because when the next command RUN command is executed a new 'layer' is created and whatever the cd did is gone. – Samarth S Oct 24 '22 at 22:13

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.

One first has to remove all packages from the `PowerTools` repository before `distro-sync`, which are being duplicated. Some of `mirror.centos.org` seems to be `vault.centos.org` (archived) now. – Martin Zeitler Feb 12 '22 at 12:59
Unfortunately, I hit this error when trying to download wget to the base centos-8 image. @BigCat's suggestion worked for me. – Kevin Mooney May 12 '23 at 13:52

Go to /etc/yum.repos.d/

cd /etc/yum.repos.d/

Run

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

Then do what you want

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.

I think "dnf distro-sync" will undo the changes made by the 2 prior sed commands – user1754036 Apr 07 '22 at 21:25
dnf does not change its configuration under /etc . Checkout **man dnf**. It just upgrades, downgrades or keeps selected installed packages to match the latest version available from any enabled repository. – Daniel Andrzejewski May 09 '22 at 16:16

And yet, after the "dnf distro-sync" finishes running, entering grep "baseurl=http://mirror.centos.org" /etc/yum.repos.d/CentOS-* shows what it would show before the 2nd sed command. https://pastebin.com/PBbwES3A If we skip the "dnf distro-sync" command, java will install. – user1754036 Jun 06 '22 at 14:12
Here's the full output generated by dnf distro-sync https://pastebin.com/mMZkkbCL note the changes to /etc starting at line 1476 – user1754036 Jun 06 '22 at 14:18

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.

It is not just an example, execute the commands as they are. If you are not root, prefix them with `sudo`. If you need them in a docker file, prefix them with `RUN`. – stackprotector Mar 11 '23 at 09:31

Please follow the below-mentioned steps:

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

cd /etc/yum.repos.d/
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-*
Then run yum update or install any package you want

yum update -y

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

Mine had to be a mixture of some of the other answers. I used latest (as of a couple days ago) CentOS with Docker default image. (sudo failed as I was already in 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-*
yum install PACKAGE

no update of yum was needed

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

open file in vi

sudo vi /etc/yum.repos.d/CentOS-Linux-BaseOS.repo
comment mirrorlist=http://mirrorlist.centos.org/?release=$releasever&arch=$basearch&repo=BaseOS&infra=$infra

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

yy and p
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
save and exit vi

:wq

Repeat above 5-steps for other .repo files.
