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:

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 doesn’t resolve the issue?
