Elevate CL7 with hybrid kernel error

Issue

Elevate CloudLinux 7 with a hybrid kernel to CloudLinux 8 failed

Environment

• CloudLinux 7 hybrid
• Elevate

Solution

1. Switch CLN channel to CloudLInux 7
   

   # /usr/sbin/cln-switch-channel -t 7 -o -f

2. Convert the server back to the normal kernel by running the following commands:

   # hybrid-to-normal

3. Ensure that cl7h repo disabled
   

   # yum-config-manager --disable cl7h

4. Check that non-hybrid kernel set as default

   # grubby --default-kernel
   /boot/vmlinuz-3.10.0-962.3.2.lve1.5.83.el7.x86_64

5. Reboot the server to apply the normal kernel and start the Elevate process again. 

Cause

The hybrid kernel is not supported by Elevate.
