Unable to find kernel headers

[Avinash Maurya]

Hi,

I am not sure if this is the right place to ask, but while installing mOS, I encounter the following error:

dkms: running auto installation service for kernel 5.10.46_0.9.mos

Error! Your kernel headers for kernel 5.10.46_0.9.mos cannot be found at /lib/modules/5.10.46_0.9.mos/build or /lib/modules/5.10.46_0.9.mos/source.

You can use the --kernelsourcedir option to tell DKMS where it's located.

I have used the following steps to install mOS on a fresh install of CentOS Linux release 8.4.2105 running kernel 4.18.0-305.19.1.el8_4.x86_64.

In /var/lib/dkms/, I see the following files/folders:

dkms_dbversion

e1000e

emulab-ipod-dkms

megaraid_sas

mptsas

mptspi

When I remove/rename the /var/lib/dkms, I am able to install mOS without any errors, but after completing the install and rebooting (with grub params), the machine goes into dracut initqueue timeout. 

I tried asking the datacenter team, but they said this might probably have to do something with the mOS kernel. Any hint would be really helpful.

Thanks,

Avinash
