I've read the Odoo 11 install documentation and it's stated that it works on Ubuntu versions 16.04 lts, 17.04 and 17.10.

https://www.odoo.com/documentation/11.0/setup/install.html

Because the fact that Python has end of life at the end of 2019 and Ubuntu 16.04 lts to april 2021 I need to migrate my Odoo 10, custom modules. 

I'm wondering if Odoo 11 (Odoo 11.0 deb package) is supported on Ubuntu 18.04 LTS?  Or is Debian a better choice?
I know that Odoo 10 had some problems on Debian that's why we switched from Debian to Ubuntu.
