Overview

You may be experiencing an issue with saving the configuration to the ./winroute.cfg file in Kerio Control, and constantly getting the below error message:

[05/Dec/2023 07:17:32] (30) Error saving configuration to ./winroute.cfg

Despite checking permissions and ownership of the file, and even after remounting the filesystem as read-write, the error would reappear after a system restart. Various troubleshooting methods, including a factory reset and enabling and disabling SSH from the appliance web interface, were attempted but the issue persisted.

Solution

This error usually indicates an issue with the actual filesystem of the appliance. In order to resolve this issue, you should install Kerio Control on a new machine and load the backup onto it. Here are the steps to follow:

1. Deploy a completely new machine. This is not a factory reset of the existing machine, but setting up a new one: Installing Software Appliance on bare-metal server
2. Proceed with Exporting configuration backup from the original appliance
3. Import the backup from the old machine to the new one.
4. After the backup is successfully imported, the old machine can be turned off and the new machine can be used without any issues.

Summary

By installing Kerio Control on a new machine and loading the backup onto it, the issue of not being able to save the configuration to the ./winroute.cfg file in Kerio Control should be resolved, and the error should not reappear after a system restart, since the new appliance does not have issues with its filesystem.

FAQ

1. What if the error reappears after a system restart?
   If the error reappears after a system restart, it is recommended to repeat the process of installing Kerio Control on a new machine and loading the backup onto it.
2. Can I just do a factory reset of the existing machine?
   A factory reset of the existing machine was attempted in this case but did not resolve the issue. It is recommended to set up a new machine.
3. What if I don't have a backup of the old machine?
   It is crucial to have a backup of the old machine to import to the new one. If you don't have a backup, you may need to manually configure the new machine.
