Signed Kernelmodules vmmon and vmnet not loaded.

[VMware Community Member]

I followed this https://kb.vmware.com/s/article/2146460 which seems to have worked:

 

 

$ sudo /usr/src/linux-headers-`uname -r`/scripts/sign-file sha256 ./VMware.priv ./VMware.der $(modinfo -n vmmon)
$ sudo /usr/src/linux-headers-`uname -r`/scripts/sign-file sha256 ./VMware.priv ./VMware.der $(modinfo -n vmnet)
$ sudo mokutil --import VMware.der 
SKIP: VMware.der is already enrolled

 

 

but i still get:

 

 

$sudo vmware-modconfig --console --install-all

instead of vmlinux i can find vmlinuz:

 

 

$ ls /boot/
    vmlinuz
    vmlinuz-6.1.0-1020-oem
    vmlinuz.old

 

 

can sombody please assist me in making this work? I am using Ubuntu 22.04LTS on a T14 gen4 (AMD).

It has to be done the other way around:

sudo vmware-modconfig --console --install-all

BEFORE doing the all steps specified in the https://kb.vmware.com/s/article/2146460

The build of both vmmon and vmmnet were successful that is why the start of the services were attempted but failed because the new keys were not generated and enrolled.

I did it the other way around. The mistake was to rerun it after signing to check if something had changed. That changed the modules hence they could not be loaded.

Thanks for answering me
