Kolibri delete of Khan Academy content does not work

I am using Kolibri .13, and have the full Khan Academy downloaded. I would like to delete subsections in Math, etc. However, when I use the ‘Manage’ interface to delete those sections the task starts and never moves past 0%. I left it running for over 12 hours with no progress.

Kolibri is running on Ubuntu 16.04.

I would appreciate any assistance.

Hi - some follow-up questions:

  • Would you mind checking whether there are any errors in the logs, and posting them here?
  • While progress was frozen, could you tell if Kolibri was using CPU?
  • Does restarting Kolibri help?

thank you!
