Uploading local contents to local kolibri server or on kolibri studio

Hello Kolibri community,

Thank you very much for the initiative of Learning Equality Community and Kolibri.
Your work is so valuable to our community, especially for learners from the community who don’t have access to the Internet.

I have started using Kolibri recently to support my local community here in Tanzania, working with a local organization that also supports local community education. I was able to install the server, thank you for the good documentation, but I am stuck on how to upload my local learning material, especially BOOKS and PAST PAPERS.

From my online reading, I can see you can upload your content to Kolibri Studio and then sync it to your local server, but when I try to create an account on Kolibri Studio, it says my email already exists, and this happens even when I use a new email address. Also, on the local server tried different options of importing either on the command line or on the web, but neither of the options worked.

I would like to get assistance on how to upload local content on either the local server or Kolibri Studio. My apologies if I post something that is already resolved. I tried to search on the forum without luck, am running Kolibri 0.18.1 on Ubuntu 24.04

Thank you in advance,
James
