This is the error log I got for when deploying my update. I believe that the error is somewhere related to the Download\_Leave script.

1. What might have been the issue?

2. Also, do I need to make any configuration to use Download\_Enter and Download\_Leave scripts that are inside etc/mender/scripts directory ?

Here is my error log:

This just an information print, and should be harmless.

This seems to be your error, and indeed it seems that a Download\_Leave script is failing.

Here is the full line for the Download\_Leave error. Can you explain what problem is it addressing to ? I didn’t quite understand the version issue.

{“level”:“error”,“message”:“transient error: error executing leave script for update-after-store state: error running leave state script(s) for Download\_Leave state: statescript: The version read from the version file in the statescript irectory does not match the versions supported by the client, please make sure the file is present and formatted correctly (supported: [2 3]; actual: 0).”,“timestamp”:“2020-09-24T16:51:13+01:00”}

There is a file that is normally created by Yocto or mender-convert in /etc/mender/scripts/version that contains the version number of state scripts supported. You can see how it’s created with [mender-convert here](https://github.com/mendersoftware/mender-convert/blob/a82b5896e6b2f9a412539e943ffc21cfb867d362/mender-convert-modify#L242).

You need to ensure that file exists with whatever mechanism you use to generate your build.
