• Vagrant provision fails to execute the next script without an obvious reason why

  14 juin 2016, par JakeTheSnake

  I’ve created/co-opted several bash scripts to provision my guest Ubuntu 14.04 OS ; the one giving me trouble right now is installing ffmpeg. When the script finishes, vagrant simply does nothing save for sending SSH keep-alives.

  Host OS : Windows 7 x64

  The last output before the infinitely repeating keep-alives is :

  INSTALL libavutil/sha.h
  
  INSTALL libavutil/sha512.h
  
  INSTALL libavutil/stereo3d.h
  
  INSTALL libavutil/threadmessage.h

  INSTALL libavutil/twofish.h
  
  INSTALL libavutil/version.h
  
  INSTALL libavutil/xtea.h
  
  INSTALL libavutil/tea.h
  
  INSTALL libavutil/lzo.h
  
  INSTALL libavutil/avconfig.h
  
  INSTALL libavutil/ffversion.h

  DEBUG ssh: stdout: Done
  
  
  
  DEBUG ssh: Sending SSH keep-alive...

  Here are the relevant scripts :

  I won’t include the other scripts for the sake of brevity. When logging into vagrant with the gui nothing seems out of the ordinary, and ffmpeg is available...but nothing else is provisioned. No RVM, no Nginx, nothing.
