get some problems after installing wizard mounter and "apt-get install kernel-module-nls-utf8 kernel-module-ntfs samba-common nfs-common"

when I want to remove it again I get the following error message:

Errors were encountered while processing:
samba-common
E: Sub-process /usr/bin/dpkg returned an error code (1)

What does it mean, and how can I remove all changes I have made when installing packages from above?

Thank you!
