Bug 10597

The stack trace of python calls that resulted in this exception/failure was:

I accidentally ran into this too and looked into it a bit.

There are two kernels in the package feed which Provides: the same
functionality. The one that's built afterwards is tracked in pkgdata
as runtime-reverse but the package manager has installed the other
(returned by image_list_installed_packages).

One more case about the failure.

I got the similar errors while I building meta-selinux and changed the refpolicy provider by setting 'PREFERRED_PROVIDER_virtual/refpolicy = "refpolicy-minimum"' in local.conf.

Steps to reproduce it:
1) Setup a build with meta-selinux layer included, and update local.conf:

+ DISTRO ?= "poky-selinux"
+ PREFERRED_VERSION_refpolicy-mls ?= "2.20161023"
+ PREFERRED_VERSION_refpolicy-standard ?= "2.20161023"
+ PREFERRED_VERSION_refpolicy-mcs ?= "2.20161023"
+ PREFERRED_VERSION_refpolicy-minimum ?= "2.20161023"
+ PREFERRED_VERSION_refpolicy-targeted ?= "2.20161023"

2) Run build with "bitbake core-image-selinux"
3) Change refpolicy provider with:

+ PREFERRED_PROVIDER_virtual/refpolicy = "refpolicy-minimum"

4) Run "bitbake core-image-selinux" again, then below error occurs:

I have changed the package provider as B, but it still search files from A.

In the years since 2017, the code has changed a lot and we now clean up sysroots much more carefully in circumstances where providers change. I don't believe this error can occur any more.
