package management - how to reinstall libsnpav0/libspnav0

E:The package libspnav0 needs to be reinstalled, but I can't find an archive for it.

and no one working: not Ubuntu Software Centre, nor Synaptic. I tried to use apt-get - the same:

sudo apt-get install libsnpav0
Reading package lists... Done
Building dependency tree       
Reading state information... Done
E: The package libspnav0 needs to be reinstalled, but I can't find an archive for it.

BUT!!!
see carefully, please! my typed request - about libsnpav0, but system answer - about libspnav0. and if I shange this letter in request - the answer not changing... just mistery...

AND there is no one trace of this lib in the
/var/lib/dpkg/status

so, how to install this lib?

thanks for advance )
