Unable to install cloudron on fresh ubuntu install (french version)

[nanuq]

Hello, i did reinstall successfully a fresh installation this morning and i'm failing while trying this afternoon.

All seemed ok for the ubuntu installation, i did the apt update/upgrade but i keep having this failure while installing cloudron :

Maybe i should install the server in english?

Looks like the DNS resolution is failing. Can you explain your environment and check if you can resolve any host from the system via SSH? Is the unbound service working?
