Installing on Ubuntu: incompatible version of cryptography when import relations into database

Technical Help
1

I am installing baserow on ubuntu for the first time using this guide: Installation on Ubuntu // Baserow

On a step " Install dependencies for & setup Baserow" after command pip3 install -e ./baserow/backend I got a warrning :

pyopenssl 22.0.0 has requirement cryptography>=35.0, but you'll have cryptography 3.4.8 which is incompatible

And then on step " Import relations into database" after command baserow migrate i got an error:

(env) root@baserow:/baserow# baserow migrate
Traceback (most recent call last):
  File "/baserow/env/lib/python3.7/site-packages/pkg_resources/__init__.py", line 583, in _build_master

Please, help to install compatible version of cryptography

@danila I’m working on fix for this for the next version of Baserow. if you want to try get it working asap you could try run the following command and see if it fixes baserow migrate:

pip3 install cryptography==36.0.1

Unfortunately, it didn’t help. maybe I must reinstall backend after pip3 install cryptography==36.0.1 or something else?

Ah this error means you also need to change the cryptography version found in the file in the Baserow repo backend/requirements/base.txt so that line looks like this instead:

cryptography==36.0.1

And then you should be able to just do:
pip3 install -e ./baserow/backend again hopefully.

thanx! I finish instalation on ubuntu server in local network! (except HTTPS / SSL Support)
How can i reach frontend and login?

if I try to go to http://192.168.103.109/ or http://192.168.103.109/ I see Bad Request (400)

Are you attempting to reach the machine from another computer on your network? If so then you need to set some extra environment variables to make this work currently:

  • PUBLIC_WEB_FRONTEND_URL needs to be http://192.168.103.109:3000
  • PUBLIC_BACKEND_URL needs to be http://192.168.103.109:8000

See this section of the ubuntu install for more info: Installation on Ubuntu // Baserow
