An attempt to commit /etc changes to bzr failed.

within apt-get upgrade (psensor psensor-common psensor-server) I have got error:

Commit failed
An attempt to commit /etc changes to bzr failed.
You may manually resolve the issues with the uncommitted changes before continuing.

This bug supposed to be solved according to "bug: #872553 [SRU] upon creating a node via juju & orchestra, etckeeper hangs"
but it is not.

other coresponding error messages:
bzr: ERROR: Could not acquire lock "/etc/.bzr/checkout/dirstate": [Errno 11] Resource temporarily unavailable
etckeeper warning: bzr add failed
