Ошибка failed to download metadata for repo appstream centos 8

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

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.

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.

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.

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
