Thanks again for your reply,
To be specific, I did exactly this:
- Install linux source code, then copy the mentioned file to the folder
using: cp /usr/src/linux-headers-5.4.0-59/fs/mount.h /lib/modules/$(uname
-r)/build
- Run sudo dkms autoinstall (I also did reboot)
- Create the session and attempt to add the context
However, I'm getting the same error.
