Hi,
I’m using Mender 2.0 in stand-alone mode and as part of the security requirements, I need to remove the _ca-certificate_ from the Yocto (we are using sumo version).
When I removed the _ca-certificate_, the below error pop ups:
I would like to know whether mender stand-alone required _ca-certificate_? If not, then may I know how to remove it?

Have you tried creating a mender\_%.bbappend file in your own projects layer and adding something along the lines of to remove the RDEPENDS addition by the mender-install feature.
`PACKAGECONFIG[mender-install]_remove("ca-certificates")`
the syntax above may not be totally correct, so further reading can be found below:

Thank you for your quick support.
I tired to remove the ca-certificates directly from the meta-mender-core layer (meta-mender-core/recipes-mender/mender/mender.inc) as below:
From:
`PACKAGECONFIG[mender-install] = ",,,mender-artifact-info ca-certificates"`
To:
`PACKAGECONFIG[mender-install] = ",,,mender-artifact-info"`
This build without any error. I hope removing the ca-certificate from here will not impact the stand-alone mender functionalities.
However, your method is more standard and preferred because we don’t have to modify the default mender layer configurations. I will try to do the same.
Thank you again 👍

Thank you @dellgreen for your support.
I tried to add the removal part in the mender\_%.bbappend file from our own project layer.
However, the ca-certificates couldn’t able remove using any of the below trials:
> 1. PACKAGECONFIG\_remove[mender-install] = “ca-certificates”
> 2. PACKAGECONFIG[mender-install]\_remove(“ca-certificates”)
> 3. PACKAGECONFIG[mender-install]\_remove = “ca-certificates”
All the above 3 methods gave build error 🤯
I know this is basic Yocto, however, I would like to know what is the correct syntax for removing the _ca-certificates_ from mender-install which is mentioned in the mender core layer?

That’s an interesting idea; I’ve never tried that myself and honestly I’d be surprised if it worked. I think you may need to simply override the entire `PACKAGECONFIG[mender-install]` definition in your bbappend file using the syntax you specified above:
> PACKAGECONFIG[mender-install] = “,mender-artifact-info”

I haven’t tried this, but given that the package config instruction looks like it indirectly is adding to the RDEPENDS variable, I would check this variable when running the mender recipe with bitbake -e mender | grep RDEPENDS to see if it’s updated. If so you could try something like RDEPENDS\_${PN}\_remove = “ca-certificates” in you bbappend recipe
