When trying to yum install -y yum-utils

Lab 1 on docker

It is a known issue due to RedHat suddenly retiring CentOS 8.
Engineers are working to upgrade the labs

Alright good to know thank you :raised_hands:

There is a work-around if you want to get though the task before they upgrade the labs:

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-*

This will fix yum and dnf so that they can find the archived versions of the repository.
