Cant generate channel listing in Khan

Support Kolibri

Hi, using a fresh install of Kolibri 0.9 on mint 18. When going to import data from Khan, it gets stuck at generating channel listing. The kolibri.log has errors:

django.db.utils.OperationalError: database is locked

The server.log has:

I saw an update roll out on the ppa, and I installed and rebooted. Is this something I can fix or shall I wait for another update?

Thanks,
Kurt

Hi Kurt,

Thanks for reaching out. We are aware of this issue and our team is currently investigating why it’s stalling at the “Preparing” stage. Any updates will be posted in the currently open Github issue at https://github.com/learningequality/kolibri/issues/3497. Once it’s been resolved, it will be included in an upcoming patch or release version of Kolibri.

Best,
Laura

Thanks for the report, and for your patience! This seems a bit different than issue #3497, and I’m thinking the errors you’re seeing in the log may be unrelated (just interspersed with the channel metadata import activity). For Khan Academy specifically, generating the channel listing can be time-consuming (several minutes, as it goes through and imports a massive amount of database entries for all the KA content), but should complete eventually. If you’ve left it > 10 mins and it still doesn’t complete, please let us know so we can help debug.

We just released Kolibri v0.9.1, which we expect should resolve the related issue (#3497). The PPA has been updated, so you should be able to update through that and give it another try.

For others coming to this thread: you can download 0.9.1 here (and please let us know how it goes): https://learningequality.org/download/

hello @jamalex , good to hear #3497 has been resolved. Am using kolibri 0.9.0, how do I upgrade to 0.9.1?

@jamalex i did a sudo update followed by a sudo upgrade, which ended with the following message

Trying to run kolibri with sudo service kolibri start gets me

What could be the issue?
PS - I already had OpenStax content before doing the upgrade, is this lost to me?
