I had this error message popping out in VCSA when I tried to perform an update via the VCSA gui (https://vcsa.fqdn:9458) and basically, the update process wouldn’t start.
I also couldn’t change the root password as I was getting into another issue Permission Denied. Set the maximim number of days when the password will expire.Administrator configuration updated successfully.
In order to get this solved quickly and be able to start your VCSA update process, open first a ssh session to your VCSA and change your root password by typing passwd.
After this step, you can move on to your update process.
