After compiling and installing pcan, I am getting the following error when tying to modprobe:

> sudo modprobe pcan
modprobe: ERROR: could not insert 'pcan': Operation not permitted
modprobe: ERROR: ../libkmod/libkmod-module.c:990 command_do() Error running install command 'modprobe --ignore-install pcan' for module pcan: retcode 1
modprobe: ERROR: could not insert 'pcan': Invalid argument

I looked at the solution to this similar post, but my linux kernel versions match:

I am on Ubuntu 20.04, and I have attached my compile and install logs.

My problem was resolved by disabling secure-boot. I followed the link from another post to this page to disable secure-boot:

Hello,

Thank you for your feedback.

Yes, secure-boot will prohibit loading the PCAN-driver,
as it is not signed.
