A common error that system admins encounter when trying to install a new package or update CentOS 8 is the following:

Error: Failed to download metadata for repo 'AppStream': Cannot prepare internal mirrorlist: No URLs in mirrorlist

To resolve this error you need to change the mirrors to Follow the next steps for the list of commands you need to execute on your CentOS 8 server to fix this.

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

[root@centos8-server ~]# cd /etc/yum.repos.d/

Step 2 — Execute the ‘sed’ command. Sed is a popular linux command for finding & replacing strings in a file

[root@centos8-server ~]# sed -i 's/mirrorlist/#mirrorlist/g' /etc/yum.repos.d/CentOS-*

and then this command:

[root@centos8-server ~]# sed -i 's|#baseurl=|baseurl=|g' /etc/yum.repos.d/CentOS-*

Step 3 — You are all set, now try updating your system with the following command:

[root@centos8-server ~]# yum update -y
