I have Docky installed on Ubuntu 10.10 64bit and noticed after a recent upgrade my 'Helpers' are no longer available. After some research I found that Dockmanager is no longer installed either.

I am unable to install it via the Software centre or via terminal using apt-get, the following error is returned;

mark@Sonata:~$ sudo apt-get install dockmanager
Reading package lists... Done
Building dependency tree       
Reading state information... Done
The following NEW packages will be installed:
0 upgraded, 1 newly installed, 0 to remove and 0 not upgraded.

dpkg-deb: subprocess paste killed by signal (Broken pipe)
Errors were encountered while processing:
E: Sub-process /usr/bin/dpkg returned an error code (1)

Can anyone advise on how to fix this?

I'm having this same issue. I'm unable to purge the Faenza package and when I try to remove it with the software center or Synaptic, I get an error. – user10284 Feb 5 '11 at 22:16

What's happened is that when you updated, it tried to install an update of the dockmanager, but a theme package you installed previously has done naughty things and replaced one of the dockmanager's files.

To fix you need to do the following:

sudo apt-get purge faenza-icon-theme

Then try and reinstall your dockmanager, you also need to report to the maintainer of faenza-icon-theme that he's made a broken package and he should fix it as soon as possible. Basically he needs to make it so that it doesn't replace files from other packages.

The easiest way to do this is:

sudo apt-get remove dockmanager
sudo apt-get purge faenza-icon-theme
sudo apt-get install dockmanager faenza-icon-theme
