Description of my issue
ENG
Hello !
Debian 11 fresh installed, I’m trying to install Yunohost with the script as described here : Installer YunoHost | Yunohost Documentation
The script fails at the start, when it tries to update the system.
Maybe it’s something easy to solve but I don’t see what’s wrong, please send help !
