unable to play video after upgraded to ubuntu 16.04 from 14.04

[Ralf Mardorf]

Perhaps the original poster's default language is an issue.

李白|字一日 <calidion at gmail.com> please run the commands this way:

  sudo -i
  LANG=C apt-get update
  LANG=C apt-get dist-upgrade
  logout

If any warnings and/or errors occur copy and paste just the
warnings and/or errors and stop, do not continue with the following
commands. Assumed no warnings and/or errors occur, then do not post the
output, but continue with the following commands:

  sudo -i
  LANG=C rm /var/cache/apt/archives/ligbm*
  LANG=C apt-get install --reinstall libgbm1
  LANG=C ls -l /usr/lib/x86_64-linux-gnu/libgbm*
  logout

What ever output you get for those commands, consider to
post everything to the list.

LANG=C runs the command with an English locale.

Regards,
Ralf
