Problems of Using dnf

• dnf (a software to update the system) is needed in some of the lab exercises
• Due to the end of the support of the CentOS 8, the CentOS dev team moved the software repository to another location.
• In order to use dnf, please run the following commands:
  
  

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

• Please type these 2 commands carefully. These 2 commands use regular expression to replace the old software repositories with the new destination

Overview

• Topics will be discussed in the morning lecture
• The topics will be related to the lab exercises, so missing the lectures may waste you more time because you need to figure out how to complete the lab exercises by yourself
• There won't be attendance taking during the morning lecture
