branch/source builder: branch-source-builder/watch_ppa.py:177: undefined name 'UPLOAD_LIST'

UPLOAD_LIST is not defined and it's not obvious to me what it should reference.

172 # TODO UPLOAD LIST is not ready for use via the CLI yet.
173 # The original cu2d tools extracted this from files stored locally
174 time_start = time.time()
175 while True:
176 (ret, status) = watch_ppa(time_start, series, ppa,
177 args.destppa, args.arch, UPLOAD_LIST)
178 if ret == -1:
179 time.sleep(TIME_BETWEEN_PPA_CHECKS)
180 else:
181 return ret
