I am on ubuntu 14.04 and have installed uget from the official ppa and also installed flashgot addon for firefox. In addition I have also downloaded the aria2 plugin and enabled it in the plugin settings of uget. The problem is whenever I try to download any video from youtube, uget just downloads a small file named "watch" which is of around 180 KB and says download complete. I have tried searching for the solution but they were for older versions of uget and didn't work for me. Any insight will be helpful. Here are the link to the screenshots.
