In the recent Ubuntu 18.04.2 on Hyper-V, I noticed that an error keeps popping up to my terminal:
[%] print_req_error: I/O error, dev fd0, sector 0
After searching the problem, the following commands help resolve the problem
Execute the following with sudo
# rmmod floppy
# echo "blacklist floppy" | tee /etc/modprobe.d/blacklist-floppy.conf
# dpkg-reconfigure initramfs-tools
