Comment 4 for bug 1070443

Workaround for me:

1. download packages from presice pangolin:
http://packages.ubuntu.com/precise/loggerhead
http://packages.ubuntu.com/precise/bzr
http://packages.ubuntu.com/precise/bzr-search
http://packages.ubuntu.com/precise/python-bzrlib

2. install those packages
sudo dpkg -i python-bzrlib_2.5.0-2ubuntu2_i386.deb
sudo dpkg -i bzr_2.5.0-2ubuntu2_all.deb
sudo dpkg -i bzr-search_1.7.0~bzr88-1_all.deb
sudo dpkg -i loggerhead_1.19~bzr461-1_all.deb

3. restart loggerhead service
sudo service loggerhead stop
sudo service loggerhead start

4. stop upgrading these packages
sudo echo "loggerhead hold" |sudo dpkg --set-selections
sudo echo "bzr hold" |sudo dpkg --set-selections
sudo echo "bzr-search hold" |sudo dpkg --set-selections
sudo echo "python-bzrlib hold" |sudo dpkg --set-selections
