After a fresh install of Ubuntu, my terminal was being flooded with “print_req_error: I/O error, dev fd0, sector 0” error.
This is because, your kernel thinks you have a floppy disk fd0, but cant find one. To fix this issue, you can run the following in your terminal:
sudo rmmod floppy echo "blacklist floppy" | tee /etc/modprobe.d/blacklist-floppy.conf sudo dpkg-reconfigure initramfs-tools
Misc: If you are deploying a new virtual machine, you can avoid this issue by deleting the Floppy Disk drive.
