Good day, my kolibri studio is stuck on 0% whilst publishing content. Please help
Hi @William,
Thank you for using Kolibri Studio.
It appears that your publishing task is queued and waiting on resources to become available. Currently, Studio is processing a backlog of tasks ahead of yours. I will continue to monitor things throughout the day and will take corrective action if needed.

Hi @William,
Please retry publishing your channel. You may have to refresh the page in order to do so.

Hi @William,
Could you please share your channel’s ID in a direct message (DM) to me? You can find in the circled portion of the URL shown in the image below
Hi @William,
Seems your channel was stuck again, so I’ve reset it. Could you try publishing again?

Hi Blaine,
I am a problem with kolibri studio. I guess I overloaded the publishing facility. I was trying to do a lazy man job by recreating termly course template that already contain large data of lessons. How can I purge the contents or at least get the publishing facility working again. I have been on this for more than 9 days. I have been stuck on this page for over 9 days.
The token for the channel is :
Hi @david_ally,
Thank you for your patience dealing with this issue. I’ve triggered some reconciliation which has restarted your channel’s publishing. We’ve released some enhancements this year to make this more robust, but with your report, it seems this still can happen. So please let us know if it happens again. We’ll look into why this happened to your channel specifically, too.
Kind regards,
Blaine
Hi @david_ally,
Curious - what version of Kolibri are you running? How is it deployed? I ask because this looks like how it would look if there were no task runners available to pick up the import task.
Are you seeing any errors in the console or in the logs? Troubleshooting - Kolibri User Guide
Kind Regards,
Richard
I am running kolibri 0.19.4. There is no error apart from the screen shot I sent.
I don’t know why it got stuck on waiting. I thought it was a temporary problem but I tried importing just a small portion of the content ( Less than 1Mb), and it still got the same message of “Waiting”. The resource is iclasse-lpl-rdc.online.
Hi @david_ally,
So it looks like this is deployed online? How has it been deployed? Where are the task workers running? Are you using a SQLite or Postgresql backend?
It looks very much like the task workers are not running.
Kind Regards,
Richard
It is running on cloud VPS. It is kolibri-server with all default database- is that SQLite? I did not use any special database. And import and every other aspects of the system were running fine before. So how do I check for the task workers and correct them?
One important aspect of kolibri-server is that the web requests are served by uwsgi via nginx, while the task workers are run using the kolibri services command. If this has stopped then the task workers would fail. I would start there by looking to see if kolibri services is running in the background or not.
If you want to try a quick fix just restarting the kolibri-server service should restart it - unless there’s a persistent error that is preventing it from starting.
the service failed, and it looks it had been in that state for some days. this is the error; "× kolibri.service - LSB: kolibri daemon, an offline education platform
Loaded: loaded (/etc/init.d/kolibri; enabled; preset: enabled)

And it is not restarting either. Service restart failed with "sudo service kolibri restart
Job for kolibri.service failed because the control process exited with error code.
See “systemctl status kolibri.service” and “journalctl -xeu kolibri.service” for details.
"
I did an upgrade to the newer version after stopping the running instance, and it is still not restarting
Are you able to take a look at the log files on the server? I linked how to find them above, that might give us some clues why the service is failing.
This is from the server log

Hi @david_ally
I meant the Kolibri logs themselves, as described here: Troubleshooting - Kolibri User Guide
There may be an error happening that is being reported in them which might explain why the task workers are not starting.
Kind Regards,
Richard
