I've just updated oe-core whilst trying to test my in-development
version of opkg using externalsrc and I'm getting:

 *** 0022:        for task in covered:
     0023:            bb.build.deltask(task, d)
     0024:
Exception: NameError: global name 'covered' is not defined

I don't really know the code in question well so I don't know whether
the solution is to remove that last for loop or to add back in the
declaration of 'covered'.
