Fresh install on Debian Buster, following this install guide, adapted to Buster.
On reboot, I get this:

Loading Linux 5.0.21-3-pve ...
error: /boot/vmlinuz-5.0.21-3-pve has invalid signature.
Loading initial ramdisk ...
error: you need to load the kernel first.

and will not boot using that kernel. However it will boot using 4.19.0-6 from Debian

Any pointers?
Thank you!!
 
hmm - seems the error-message is Secure Boot related (maybe the simplest workaround would be to disable secureboot in BIOS)

Maybe the documentation on Secure Boot from the debian-wiki can help if you want to use Secure boot - https://wiki.debian.org/SecureBoot

Which boot-loader are you using on that system?

I hope this helps!
 
Glad it solved the problem!
