You are targeting an old version of Odoo!
Heading: The latest released version is Odoo v13. It seems from your repository here, that you are building a Cloudron package for Odoo v10.
Let me contribute something here: Here is an installer script of community edition for selfhosted scenarios, which does the entire installation from 1 install sequence:
v13 runs fine on a USD5 droplet on DigitalOcean
Note: The Odoo federation/company is removing features from the Odoo Community edition. That sucks. However; In some cases they are adding features, but the heaviest are being removed. And in addition the latest is still becoming better and better, and more and more resource efficient.
As such I propose to develop this Cloudron install package for all the latest major-version editions. v10, v11, v12 and v13. See the github link in this issue-item, and look for earlier versions of the script under the github-branches section.
Also: Massive thanks for doing this. I hope you will take my comment here into account.
