<type 'exceptions.NameError'>: global name 'logging' is not defined

[Jeremy Price]

Binary package hint: aptdaemon

After the software center crashed earlier, I tried to do a system update which listed, among others, an update to the software center. The update manager crashed before it started downloading the updates. The crash generated the following error:
Traceback (most recent call last):
  File "/usr/lib/python2.7/dist-packages/aptdaemon/worker.py", line 166, in _process_transaction
    lock.wait_for_lock(trans)
  File "/usr/lib/python2.7/dist-packages/aptdaemon/lock.py", line 163, in wait_for_lock
    logging.error("Failed to lock the cache")
