power edge R750 boot fail after linux kernel update
Installed a Ubuntu 20.04 server OS on a R750 & no problem, then in error when updating the linux kernel version to 5.7.19. No new hardware is installed.
When compiled the 5.7.19 kernel, the error below happened and solved by setting CONFIG_SYSTEM_TRUSTED_KEYS to NULL (it used to be "debian/canonical-certs.pem")
No rule to make target ‘debian/canonical-certs.pem‘, needed by ‘certs/x509_certificate_list‘The server boots with no problem when chooses the original kernel version (5.4.0 in Ubuntu 20.04).
No Events found!

When I checked from here "This system was tested with 20.04 LTS, running the 5.4.0-72-generic kernel." I had seen. https://dell.to/3Gz4gAJ;
