We have a bunch of workstations installed on CentOS 7.4. We want to start implementing the switch to CentOS 8 but it’s already not going as planned.
First installation from usb:
sudo dd if=/prod/library/install/os/centos/CentOS-8.2.2004-x86_64-dvd1.iso of=/dev/sdc
From the CentOS installation menu, we choose Install Centos 8.2… and no matter what type of installation we choose (EFI or Bios), we always get the following error:
dracut-pre-udev(885): modprobe: FATAL: Module floppy not found in directory /lib/modules/4.18.0-193.el8.x86_64 dracut-pre-udev(885): modprobe: ERROR: could not insert 'sha256_mb': No such device ( ok ) Started Show PLymouth Boot Screen. ( ok ) Started Forward Password Requests to Plymouth Directory Watch. ( ok ) Reached target Local Encrypted Volumes. ( ok ) Reached target PAths.
And then nothing else ever happens even if the machine still on.
However, if in the CentOS installation Menu, we choose Troubleshooting and then Install CentOS Linux 8 in basic graphics mode, we are able to perform the installation.
How could we solve this? We need to be able to run basic installation for the deployment, previously done with tfpt and kickstart.
