Virtually no system has a floppy disk drive anymore but you will often find your Linux distribution insists that you do or should have one :)

The solution is to remove the floppy module and prevent it from loading on the next reboot.

rmmod floppy

Centos/RHEL

echo "blacklist floppy" >> /etc/modprobe.d/blacklist

Debian/Ubuntu

sudo echo "blacklist floppy" >> /etc/modprobe.d/blacklist.conf
