  2. Now that you know which package /usr/lib32/libstdc++.so.6 came from, you can find out which packages depend on lib32stdc++6 by running:

    sudo apt-cache rdepends lib32stdc++6

    This will give you a list of package(s) that depend/installed lib32stdc++6

  3. Another solution is to use the tool apt-file :

    • Install it using :

      $ sudo apt-get update && sudo apt-get install apt-file

    • Update it's database :

      $ sudo apt-file update

    • Search for your desired file : 

      $ sudo apt-file search /usr/lib32/libstdc++.so.6

    The result should be : 

    $ apt-file search /usr/lib32/libstdc++.so.6
lib32stdc++6: /usr/lib32/libstdc++.so.6
lib32stdc++6: /usr/lib32/libstdc++.so.6.0.21
lib32stdc++6: /usr/share/gdb/auto-load/usr/lib32/libstdc++.so.6.0.21-gdb.py
lib32stdc++6-5-dbg: /usr/lib/debug/usr/lib32/libstdc++.so.6.0.21

/usr/lib32/libstdc++.so.6

    Which lead us to know that the package which installed should be lib32stdc++6.
