this seems to be that it is needing python2, so yes it can perhaps be ported to py3 but you might have to check if it needs some code changes Looking at the recipe it is ineheriting py2 class here [1] perhaps you should change that to python3native [1] https://github.com/kratsg/meta-l1calo/blob/add/opcServer/recipes-core/opc-ua/opc-ua-server-gfex_git.bb#L15 > > Thanks! > Emily Smith > > > >
