Hi,
I up this post because I had the same error.
What I have done :
- I installed CB with the .deb on Ubuntu with "dpkg -i thepackage1.deb ... thepackageN.deb".
- I had some error of depencies, that is why I done "apt-get -f install", and thought that CB was ready to use, in fact the plugins were not installed.
- I used a second time the "dpkg -i thepackage1.deb ... thepackageN.deb" command to install what was not, and now it's ok.
Tcho.
