When upgrading Nagios XI, the upgrade may fail with the error:
The following error message is produced:
root.crontab.orig: cannot overwrite existing file
This problem generally occurs when there are leftover files from previous upgrades.
This problem can be eliminated by running the following command:
cat /dev/null > /tmp/nagiosxi/uninstall-crontab-root
After this you can proceed to run the upgrade script again.
