I tried to installed icaclient (a remote desktop application), and it failed to install for some reason. The problem is that now whenever I try to install a new application with apt-get, I get this message even of the installation succeeded:

Errors were encountered while processing:

 icaclient:i386

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

Although applications do get installed correctly, but the message is really annoying, and it could potentially hide other errors.
