STEP 16) We use https address for the packages, one of the officials mirrors – mirror.leaseweb.com.

Set the method to HTTPS://, write the URL where are the packages and in our case, this is mirror.leaseweb.com/centos/8/BaseOS/x86_64/os/ and set the type of the URL to “repository URL”.

STEP 20) Installation destination – choose your disk to install CentOS 8.

Ensure the automatic storage configuration is selected. This might erase all of the data on the disk and will install a clean copy with default disk layout. If you do not have enough space on the selected disk, the setup will ask you to erase the data on the disk (next few steps will show the setup). If the disk is blank it will not ask you anything. If you want a specific installation you should choose “Custom” or “Advanced Custom(Blivet-GUI)” (these options are beoynd the scope of this article). Click on “Done”.
