If you're a Linux user, you may have come across the error message "Failed to download metadata for repo 'AppStream' ". This error message is commonly seen when using the yum package manager in CentOS or RHEL-based distributions. This error can be frustrating, especially if you're trying to install or update packages. In this article, we'll explore some potential solutions to this issue.

This metadata is used by the package manager to keep track of available packages, dependencies, and other information. When you see the error message "Failed to download metadata for repo 'AppStream'," it means that your system was unable to retrieve this metadata from the repository.

Fix Failed to download metadata for repo

With that in mind, let's explore some potential solutions to this issue.

1. Check your internet connection: Before trying anything else, make sure that your internet connection is working properly. This can be done by doing ping test against google.com

~]# ping google.com
PING google.com ( 56(84) bytes of data.
64 bytes from del03s13-in-f14.1e100.net ( icmp_seq=1 ttl=115 ti me=43.5 ms
--- google.com ping statistics ---
1 packets transmitted, 1 received, 0% packet loss, time 0ms
rtt min/avg/max/mdev = 43.508/43.508/43.508/0.000 ms

2. Check the repository configuration: If you've manually edited the repository configuration file, double-check to make sure that everything is correct. The file is typically located at /etc/yum.repos.d/CentOS-AppStream.repo or /etc/yum.repos.d/redhat.repo. If you're not sure what the correct settings should be, you can try restoring the file to its default state by running the following command:

sudo yum reinstall centos-release
sudo yum reinstall redhat-release

3. Disable the AppStream repo: If you're unable to resolve the issue with the AppStream repo, you can try disabling it and using another repository instead. To do this, edit the repository configuration file and set the "enabled" option to "0". For example:


4. Use a different mirror:

~]# 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-*

You can find a list of mirrors at https://www.centos.org/download/mirrors/.

5. update the repo

 ~]# yum update -y

This should solve the issue
