The Download Maps Manager (MapsBroker) service is not started and is causing alerts in the Server Dashboard. This service just starts on demand and is normally not running. There are various ways to disable the service, as on a server it’s very rare that the Mapsbroker service is actually used.
With a new install as a virtual server, Ubuntu repeatedly displays the error:
print_req_error: I/O error, dev fd0, sector 0
The reason is the virtual server does not have a floppy drive. To resolve:
# sudo rmmod floppy
# echo “blacklist floppy” | tee /etc/modprobe.d/blacklist-floppy.conf
# sudo dpkg-reconfigure initramfs-tools
The message should now be gone for good.
