I honestly have to say in the past I was doing many installations in VirtualBox and customizing and creating the image from there.
However since some time now I found that in a Virtual Machine I was always getting similar errors to yours.
Somebody once said here in the forum that doing remasters in a VM can fail. Obviously beeingstubbborn I was not trusting him, but please try all you did outside of VMware.
I'm not being stubborn, but I've had a lot of success over the years doing Linux development work in a VMWare VM. At this very moment, I have two PCLOS VMs. The 1st, contains the system image I've referred to in this thread. Yesterday, I finally made a bootable remaster based on this image, which is definitely progress, but devices aren't working properly booting on a real
PC. I set my initial image (called Experimental) aside to create another VM, called Mini, based on the LXDE-Mini ISO. I took a modestly different approach to remastering my image this time. While working on the Mini image, I think I may have figured out what's wrong with Experimental.
Anyway, I have several other active projects besides modifying PCLOS, so multiple real PCs aren't an option for many reasons. Ultimately, one must
test on a real PC....Jet
