Your ROOT_URL in app.ini is http://git.osmesh.ru/ but you are visiting http://91.221.70.94:3000/MOS/OpenBoard/src/commit/04cc58d66a4b0e4c2d7ecf4541f10c64cec99609/release_scripts
You should set ROOT_URL correctly, otherwise the web may not work correctly.
On several Linux version (Mint 18 for example) the package libavcodec-ffmpeg56 is replaced by libavcodec-ffmpeg-extra56.
To increase the compatibility I added an exception which define a conditional dependency between these two packages.
