Hi guys

I am attempting to install Airspy (before known as SDRSharp) on my Debian 9.0 and I am following this link:

https://rtlsdr.org/softwarelinux

When it gets to the line of Airspay Installation it quotes 

"Don't forget to blacklist the kernel driver as mentioned here."

which links you to this wiki site

https://github.com/airspy/airspyone_host/wiki/Troubleshooting#linux-debianubuntu

I was able to install airspy-git, gr-osmosdr, and gqrx but I get lost on the part of blacklist the kernel >= 3.17

What can I do to blacklist the kernell driver?

Thanks
