Acronis: The SnapAPI kernel module is not loaded for the kernel (Required key not available)

Issue

During the installation of the Acronis agent, snapapi module cannot be loaded, and returns the next error:

# modprobe snapapi26
modprobe: ERROR: could not insert 'snapapi26': Required key not available

Environment

• Imunify360
• CloudLinux Backup
• Acronis
• snapapi26

Solution

In case all steps, described in this article, were applied - The SnapAPI kernel module is not loaded for the kernel, but the error still persists, the issue seems can be related to Secure Boot:

# dmesg | grep -i secure
[ 0.000000] secureboot: Secure boot enabled
[ 0.000000] Kernel is locked down from EFI secure boot; see man kernel_lockdown.7
[ 0.954677] integrity: Loaded X.509 cert 'VMware, Inc.: VMware Secure Boot Signing: 04597f3e1ffb240bba0ff0f05d5eb05f3e15f6d7'

If Secure Boot is enabled the module can't be added. To get it fixed Secure Boot needs to be disabled. It can be done in the UEFI/BIOS.

The following steps should be applied after reboot:

# modprobe snapapi26
# lsmod | grep snap
# acrocmd list disks
# systemctl restart acronis_mms
# acrocmd list disks

It should help insert snapapi module and the backup should work after that,
