  1. Challenge

    Install telnet.

    First, let's become root:

    sudo -i
    

    Install the telnet package:

    yum install -y telnet
    

    Verify the integrity of the RPM database:

    cd /var/lib/rpm/
    
    /usr/lib/rpm/rpmdb_verify Packages
    

    Rebuild the RPM database:

    rpm -vv --rebuilddb
    

    Verify the integrity of the new RPM database:

    /usr/lib/rpm/rpmdb_verify Packages
    

    Query installed packages for errors:

    rpm -qa > /dev/null
    

    Install telnet:

    yum install -y telnet
    
  2. Challenge

    Install Apache.

    Install Apache:

    yum install -y httpd
    

    Edit /etc/yum.conf to remove the exclusion for httpd:

    vim /etc/yum.conf
    

    Now, try to install Apache:

    yum install -y httpd
