With a self-signed certificate, you need to arrange for the verification key to be installed in the client and added to the mender.conf file. [Details are here](https://docs.mender.io/2.5/server-installation/certificates-and-keys#mender-client)

Hi Drew,
Thanks for your suggestion I am working on it.
i have some other doubt in OS update how to expose the bootloader partition of the software in means how to get to know after every update in which partition OS is running.
how to expose the active partition after every update.
thanks for your valuable suggestion in advance.
Kind Regards
Avi999

Mender handles that automatically using bootloader environment variables. It’s stored in mender\_boot\_part\_hex which you can view with fw\_printenv. But I’m not sure why you need that information. Can you share your use case?
