The two issues I tested on Ubuntu were to first check if Secureboot was enabled (it needs to be disabled) and to also try manually loading with some different commands.

Here is a issue #56 on how installing on Ubuntu worked when tested

which is based off of issue #3 which deals with disabling Secureboot

and issue #27 which required some extra commands to install with.

The Ubuntu install also had Errors 1 and 2 but I'm not sure if they're the same.

This looks to be caused by 64 bit division on a 32 bit kernel.

I've submitted a PR to https://github.com/jlam55555/veikk-linux-driver/pull/58 to use div64_s64 from <linux/math64.h>, which should fix this.

I have got this to work on the 64 bit beta OS on a model 3 Pi.

I found that using just the 64bit kernel did not work for me.

Thought this might be useful to others.
