Hello guys!

I have just installed ReviewBoard 4.0.1 on my Ubuntu 20.04 VM and always see Error 500 when I am trying to open review board in the configured localhost.

I googled this problem and have seen that I should enable DEBUG option in the settings_local.py config file. I had done this and nothing changes. I still can't see detailed description of errors.

Could you help to figure out this problem?

Thanks!

Can you look in the Review Board and/or web server log files?

Hi David,

Log directory of ReviewBoard is empty. I have taken a look into apache2 errors log:

I have tried to install this packet directly, but without success:

mixa@mixa-VirtualBox:~$ pip install py31compat

ERROR: Could not find a version that satisfies the requirement py31compat (from versions: none)

ERROR: No matching distribution found for py31compat

I have tried to google this ImportError and have found the next page on stackoverflow - https://stackoverflow.com/questions/46998858/importerror-no-module-named-py31compat

But in fact, this didn't help, because I have already had setuptools.

Proof:

mixa@mixa-VirtualBox:~$ pip install setuptools

Requirement already satisfied: setuptools in /usr/lib/python3/dist-packages (45.2.0)

Thanks!

Hi,

Please change from ALLOWED_HOSTS=['localhost.localdomain']
to

ALLOWED_HOSTS=["*"]

It will work. Please try and let me know. I did it and found it working

Regards,

Hi Jegan,

Thanks for this advice. I have done this but it doesn't help, unfortunately.

Thanks.

This is unfortunately a bug on Ubuntu with their Python installation. A lot of projects have been impacted by this.

Try to use pip to upgrade setuptools and pkg_resources, and see if that addresses it.

Hi Christian,

Thanks for your response.

I have updated setuptools but it did not help...

Well, I didn't know about this problem with python in Ubuntu.

What is particular Linux distribution could you recommend as a platform for install the ReviewBoard?
