Hi,

I am trying to upgrade libstdc++.so.6.0.8 to a newer version in the /usr/lib
directory. I used aptitude to install libstdc++6-dev package. But the
/usr/lib so file is still not updated. I suspect that's not the package for
it.

Given an existing file, Is there any method to find out which package the
file comes from? If I can find out which package the file is from, maybe I
can guess the name of the newer package.
