Title:
  python3-libtorrent linking libboost_python27.so instead of
  libboost_python36.so

  Won't Fix

  Fix Released
Status in boost1.67 source package in Cosmic:
  New
Status in libtorrent-rasterbar source package in Cosmic:

Bug description:
  [Impact]

  Due to the libboost-python naming convention changing,
  python3-libtorrent incorrectly links to libboost_python27.so instead
  of libboost_python36.so in cosmic. The essentially renders the package
  useless.

  [Test Case]

  Run the command:

  $ python3 -c "import libtorrent"

  With 1.1.9-1 on cosmic, it will fail with:

  Traceback (most recent call last):
    File "<string>", line 1, in <module>
  ImportError: /usr/lib/x86_64-linux-gnu/libboost_python27.so.1.67.0: undefined symbol: PyClass_Type

  
  The command should exit without error in the fixed version.

  [Regression Potential]

  There is little regression potential as the package is currently
  broken without this fix.

  ----

  An error occurs when importing the libtorrent module from python 3.x
  script:

  ImportError: /usr/lib/x86_64-linux-gnu/libboost_python27.so.1.67.0:
  undefined symbol: PyClass_Type

  How to reproduce:
  1. Install packages:
  python36
  python3-libtorrent
  2. Run any python script importing libtorrent module
