I’ve been trying to download several bits of content (KA and PhET) on Kolibri for the past hour but it’s not working, doesn’t even start.
Just wondering if there is a problem with the central server and if I should try later.
Best,
Clementine
Hi @clementine,
We are sorry to hear you are experiencing problems downloading channels. Do you see the Importing content... progress bar as in the image below?
![3 (start) [Running] - Oracle VM VirtualBox_012](https://global.discourse-cdn.com/flex035/uploads/learneq/original/1X/e9d17a6f1185db8ddcbd317defffe3b3de1589c2.png)
The import operation above is running as we speak on one of ours testing machines, so Kolibri Studio (Central Server) is up and working correctly.
Could you upload the kolibri.log and debug.log files here (both are located in your home directory, inside the ./kolibri folder):
This will help us debug the problem you are experiencing.
Hi @radia-matic
Thanks for your prompt response.
I’ve uploaded a screenshot of where I get stuck. The dark purple bar is rotating in reality (this is not captured by the screenshot).
regarding the logs, ./kolibri/debug.log is blank
and here is what I get in ./kolibri/kolibri.log:

As you can see, the downloading command was fired at 21:27, and I’m doing the CP of the log now at 21:41. Nothing as moved since then.
Hello,
The problem is still not solved.
I reinstalled Kolibri and now none of the content packages is installing.
It looks as if the app was hanging when I hit the download button.
For info, I installed Kolibri using PIP (both times) on the raspberry pi (latest Rasbian Jessie OS).
When Kolibri starts I get the following message:
Your models have changes that are not yet reflected in a migration, and so won’t be applied.
Run ‘manage.py makemigrations’ to make new migrations, and then re-run ‘manage.py migrate’ to apply them.
Could these un-applied migrations be a cause for this problem?
Best,
Clementine
Hi @clementine,
Sorry for not following up your issue earlier.
I think your issue could be similar to this one here: https://github.com/learningequality/kolibri/issues/3028#issuecomment-356428642
Basically, you can run:
> python (or python 3 if that's how you installed Kolibri)
>> import urllib3
>> urllib3.__version__
to see if your urllib3 version is lower than 1.22.
If the version of urllib3 is lower than 1.22, then you can upgrade it to 1.22 by doing:
> pip install urllib3==1.22 (or pip3 install urllib3==1.22 if you installed Kolibri with Python 3)
On the other hand, we are actively developing and will have a 0.7.1 release soon to resolve this issue.
Please feel free to let me know if you have any further questions.
Regards,
Lingyi
Hi @lingyi
I’ve tried this fix but unfortunately, it didn’t work in my case.
I have urllib3.version >> 1.22 yet still the same hanging.
One thing I didn’t mention in this thread is that it used to work on my system at the beginning, I downloaded 2 content threads just after the install, and then it stopped working after this.
I reinstalled Kolibri completely and now it’s not working at all.
Hi @clementine,
I’m very sorry that it didn’t work.
Have you ever removed your ~/.kolibri folder?
If not, could you take a look at ~/.kolibri/content/databases to see what the files inside are? Does any of the files inside that folder end with .transfer?
Also, did you use Python 2 or Python 3 to install Kolibri?
If you run:
> kolibri shell
> import requests
> requests.__version__
> requests.__file__
could you copy and paste the output here?
Thank you so much! And sorry again about the inconvenience.
Hi @lingyi
I did remove the ~/.kolibri folder when I reinstalled Kolibri unfortunately.
But I still have .transfer files in the content/databases folder:
131e543dbecf5776bb13cfcfddf05605.sqlite3.transfer a53592c972a8594e9b695aa127493ff6.sqlite3.transfer
197934f144305350b5820c7c4dd8e194.sqlite3.transfer
I’m using python 3.
requests.version
2.9.1
requests.file
‘/usr/local/lib/python3.5/dist-packages/requests-2.9.1-py3.5.egg/requests/init.py’
I’m going to try and reinstall a new SD card today, to see if I can get to work again.
Will keep you posted.
Best,
Hi @clementine,
Thank you for the information! I think the problem could be caused by the version of requests. I tried to use requests 2.9.1 on my machine, and the same problem as you described here showed up. One thing I would recommend you to try is to remove your ~/.kolibri folder and then download our 0.7.1 release, in which you will be using our bundled requests 2.18.4 instead of your system package. You are now able to find it on PyPi: https://pypi.python.org/pypi/kolibri/, so please feel free to install Kolibri 0.7.1 through pip install kolibri==0.7.1.
Please do not hesitate to let me know if the problem still exists 
Regards,
Lingyi
Hi @lingyi
I’ve created a new SD card and tried reinstalling Kolibri.
I have the following problem now:
pip install kolibri==0.7.1.

Hi @clementine,
I’m very sorry that there are still problems in our 0.7.1 release. We are still trying to identify the issue and hoping to resolve this soon.
However, at this point of time, we think this issue could be related to PyPi, so I would suggest that you can go to our github release page: Release v0.7.1 · learningequality/kolibri · GitHub to download the whl file.
After that, please try:
pip3 uninstall kolibri
rm -r ~/.kolibri
pip3 install kolibri-0.7.1-py2.py3-none-any.whl (which is the whl file you just download from github)
Please let us know if there are still problems. Sorry about your experience with installing Kolibri and thank you for your patience.
Regards,
Lingyi
Hi @lingyi
I’ve tried this, but unfortunately, it didn’t solve the problem.
The error message at kolibri start is identical.
Also I wanted to mention that there is no ~/.kolibri folder at this stage.
Hi @clementine,
Can you show me the output of
ls -l /home/pi/.local/lib/python3.5/site-packages/kolibri/dist/?
Also, could you please extract the kolibri-0.7.1-py2.py3-none-any.whl file (you might be able to do this just by double clicking the file). Inside the extracted folder, please go to kolibri folder and then click dist folder. And then can you take a screenshot of what it is inside dist folder and upload it here?
Thank you so much!

Hi @clementine,
It looks that your current kolibri install in Python 3 is still from PyPi but the kolibri-0.7.1-py2.py3-none-any.whl is correct.
Do you mind trying this again just to confirm?
> pip3 uninstall -y kolibri
> ls -l /home/pi/.local/lib/python3.5/site-packages/kolibri/ [this command should get an error saying this directory doesn't exist. If in the command the directory still exist, please let me know]
> pip3 install kolibri-0.7.1-py2.py3-none-any.whl [Instead of running pip3 install kolibri, you will have to install the specific file you downloaded from our github. Also, you will have to run this in the directory that kolibri-0.7.1-py2.py3-none-any.whl exists or replace the filename with the path to the file.]
> ls -l /home/pi/.local/lib/python3.5/site-packages/kolibri/dist [please copy and paste the output of this command here.]
Thank you so much!

Hi @clementine,
thank you for the information! I think the problem here might be the new kolibri got installed to another directory.
Could you please run pip3 install kolibri-0.7.1-py2.py3-none-any.whl if you haven’t. After that, could you also run the following two commands and then paste the output here?
> pip3 --version
> pip3 show kolibri
thank you!

>>> import kolibri
>>> kolibri.__file__
After that, if you do pip3 uninstall kolibri, before you enter y to the question Proceed (y/n)? what is the line right before this question?
For example, it might be something like
/usr/lib/python3/dist-packages/kolibri/utils/version.py
Thank you!
Sincerely,
Lingyi
ls -l /usr/lib/python3/dist-packages/kolibri
ls: cannot access ‘/usr/lib/python3/dist-packages/kolibri’: No such file or directory
kolibri.__file__
‘/home/pi/kolibri/init.py’
Before uninstalling the last line is:
/home/pi/.local/lib/python3.5/site-packages/kolibri/utils/version.py
