DUB: shared libraries missing, after upgrade to ubuntu 16.04

[Nafees via Digitalmars-d]

I recently upgraded to ubuntu 16.04 LTS from 14.04 LTS. I 
formatted the whole HDD, when I reinstalled all my stuff, DUB 
won't work. When I type "dub" into the terminal, this is what 
shows up: "dub: error while loading shared libraries: 
librtmp.so.0: cannot open shared object file: No such file or 
directory"

This wasn't happening with 14.04, and I have no idea where to get 
these libraries. Google didn't help much either. I found the 
librtmp.so.1, renamed it to librtmp.so.0, but then DUB couldn't 
find another library.
How can I get DUB to work again?
