I don't know whether this question already asked or not in Askubuntu. So, what my question is now I am facing a (weired) problem while playing Youtube videos. Some of the videos streaming well but some videos are not. I am getting an error message saying that "An error occurred. Please try again later(Playback ID: some playback id). I tried both in Mozilla as well as Chrome but no luck. Flash plug-in installed correctly that's why some videos playing well. I restarted my PC and router still same problem.
I tried the following command also
sudo apt-get install ubuntu-restricted-extras
I am on Ubuntu 16.04 LTS x64
So, can anyone help me please.
