Answer by 0x8BADF00D for How to find location of installed library

In case if you are not sure about package name you could list all packages and try to find requested:

dpkg --get-selections | grep -v deinstall | grep <packagename>

For example:

$ dpkg --get-selections | grep -v deinstall | grep zip

Output:

bzip2 installgzipinstallp7zip-fullinstallunzipinstall                                                                       zipinstall  

And then:

$ dpkg -L zip

Output:
