I tried to install an image with mender-client 3.2.1 into an image with 2.6.1.
When the image with mender-client 3.2.1 starts, it performs a rollback:

Any hints what is going wrong? Which “file already exists”?

Have similar issue but I’m already on 3.2.1 mender client version. I’ve enabled debug mode and see error:
```auto
Update control map check failed: transient error: file already exists, retrying...
```
Any ideas what can cause that? Thanks.

Hey,
though it’s not the same error message it seems to point in the direction of a known issue.
Can you please confirm that the [following workaround](https://hub.mender.io/t/known-issue-in-mender-client-versions-3-1-3-2/4809) doesn’t resolve the issue?
