I was trying to install CloudLinux on an existing cPanel server, and got this error:
[email@example.com:~]sh cldeploy -k mykey Checking for an update to cldeploy Downloading version.dat (please wait) cldeploy is already the latest version (1.48) - continuing kmod-kvdo You have third-party kernel module rpm installed (see line above). It's not compatible with CloudLinux kernel. Please contact CloudLinux support at https://cloudlinux.zendesk.com/hc/requests/new
This part got my attention:
You have third-party kernel module rpm installed.
It’s not compatible with CloudLinux kernel.
The weird thing was this was a standard CentOS 7.x 64 bits with latest cPanel version installed, no 3rd party packages were installed.
The problem seems to be pretty simple, my system was shipped with kmod-kvdo package, which is not 100% compatible with Cloudlinux.
Since removing this package is not an option for me, I found a quick workaround to bypass this warning:
This parameter will avoid the kernel-header checks from the CloudLinux installation script.
In my case (key based installation):
sh cldeploy -k mykey --skip-kmod-check
But if you are using an IP based installation, this should be the command:
sh cldeploy --skip-kmod-check -i 126.96.36.199
Replace “188.8.131.52” with your real main server IP.
