Getting this error when installing linux from iso using VirtualBox 6.1. I have tried Linux 8.6 and 8.2 and both are giving same error. I also tried a workaround of disabling "Connect to redhat insight". What is solution for this ? I am really tired trying to fix this issue.
Seems like the source from where you download the images is unreliable. The best site to download RHEL is RedHat web site. You may need to create free development account for this.
If the host OS is Windows, you may want to disable the Hyper-V supervisor:
Docker (demanding Hyper-V) doesn't play well with VirtualBox or VMWare.
