Hi Benjamin,

As far as I am aware you cannot get a font into /usr/share/font on Odoo.sh. You can automatically install Python packages with a requirements.txt file and you can use imports, but not install fonts.
You could work around this by including the font within your Odoo module though. If you import and use the font from within your module it will be used as Odoo.sh downloads it from Github the moment it builds a new instance.

Regards,
