Hello,

I am trying to build the example 'conan-mosquitto _1.4.15.bb' recipe given in the doc. I am using dunfell version of meta-conan.

On running 'bitbake -k conan-mosquitto' I see the following error message:

Could you help here?

As I was debugging this problem, I found out that the meta-python layer at the branch dunfell is using the 0.15 version of the fasteners package.

The 0.15 version of the fasteners package doesn't support Python 3.8, only >Python 3.5.

Therefore, a simple solution for the problem is updating to the Honister branch, although the conan layer doesn't support this Yocto version.
