There is a security vulnerability affecting Linux at the moment called “Dirty Cow”. It affects the copy-on-write mechanism (hence the name) and can be very dangerous as it allows malicious hackers to take control of your computer or device, including the Pi. Thanks to the engineers at Raspberry Pi, there is already a fix available for our single board computers. To install it, do the following at the command prompt:
sudo apt-get update sudo apt-get install raspberrypi-kernel
Thanks to The MagPi for posting about this.
pi@raspberrypi ~ $ sudo apt-get install raspberrypi-kernel

No package raspberrypi-kernel. Where’s the mistake?
“sudo apt-get” has been depreciated, “sudo apt update” and “sudo apt install raspberrypi-kernel” is the preferred method
