Comment 5 for bug 151186

I have the same problems on a fresh install of Hardy - this occurred after attempting to install Songwrite.

Code appears as follows:

sudo apt-get install songwrite
Reading package lists... Done
Building dependency tree
Reading state information... Done
The following NEW packages will be installed:
  songwrite
0 upgraded, 1 newly installed, 0 to remove and 1 not upgraded.
2 not fully installed or removed.
Need to get 0B/536kB of archives.
After this operation, 1110kB of additional disk space will be used.

E: Sub-process /usr/bin/dpkg returned an error code (1)

And now anytime I do anything with package manager, it continues to attempt to resolve the timidity issues, so I'm getting errors everytime I use synaptic.
