Ubuntu 16 SSL error

[StefanBaar]

I am trying to install the driver on Ubuntu 16.04.
During sudo make install, an SSL error is raised.

At main.c:158:

• SSL error:02001002:system library:fopen:No such file or directory: bss_file.c:175
• SSL error:2006D080:BIO routines:BIO_new_file:no such file: bss_file.c:178
  sign-file: certs/signing_key.pem: No such file or directory

I heard that the driver works on ubuntu 14.04.
I wonder if the error is raised due to a different kernel signing process in 16.04.
