Few obvious questions:
- are you sure you are using the correct package? ESSREC package is meant for ESM/Receiver bundle (?)
- have you verified checksum of downloaded package (on the box to be upgraded)?
If you indeed have all in one box, the esserc package is the correct one.
Make sure to check that the filename was not changed on the ESM when the file was uploaded. The upgrade procedure checks for the specific filename of the tgz. If it was changed in any way, the upgrade will fail.

Hi Aszotek and Robert.
The problem was a mix of all the above, first of all the file name was changed by the sys admin when uploaded and also the TGZ file was blocked by Windows when downloaded. Clicking on the file and unblocking the tgz before uploading it again looks like it did the trick.
I d0n't really know how the unblock function works but maybe it modifies the MD5 or something similar? I know this can cause trouble on Windows but I thought that on a Linux box it wouldn't do anything.
Anyways, after upgrading to 9.4.2, enabling the ELM service and rolling out the policy everything finally works fine.
Thanks all for your help!
