• Status: RESOLVED FIXED

I hit this error when attempting to run emerge -e @world in at freshly unpacked stage3:

    dep_zapdeps: skip want_update_pkg if parent is None (bug 711400)
    
    Skip the want_update_pkg call when parent is None, since passing
    a None parent to want_update_pkg results in an error like this:
    
      File "libdep/dep_check.py", line 513, in dep_zapdeps
        if graph_interface.want_update_pkg(parent, avail_pkg):
      File "lib/_emerge/depgraph.py", line 5850, in _want_update_pkg
        depth = parent.depth or 0
    AttributeError: 'NoneType' object has no attribute 'depth'
    
    Fixes: f7d83d75c6b0 ("dep_zapdeps: adjust || preference for slot upgrades (bug 706278)")
