[ OK ] YunoHost installation completed !
===============================================================================
You should now proceed with Yunohost post-installation. This is where you will
be asked for :
  - the main domain of your server ;
  - the administration password.

You can perform this step :
  - from the command line, by running 'yunohost tools postinstall' as root
  - or from your web browser, by accessing : 
    - https://XX.YY.WW.ZZ/ (global IP, if you're on a VPS)

If this is your first time with YunoHost, it is strongly recommended to take
time to read the administator documentation and in particular the sections
'Finalizing your setup' and 'Getting to know YunoHost'. It is available at
the following URL : https://yunohost.org/admindoc
===============================================================================

On dirait que tout s'est bien passé jusqu'ici.

===== Post-installation =====
__Prérequis :__ Un nom de domaine qui pointe vers le serveur.

On peut le faire depuis la page web ( https://XX.YY.WW.ZZ/yunohost/admin/#/postinstall ) :

Ou depuis la ligne de commande :
<code bash>
# yunohost tools postinstall
Main domain: azerty.xyz
You are now about to define a new administration password. The password should be at least 8 characters long—though it is good practice to use a longer password (i.e. a passphrase) and/or to use a variation of characters (uppercase, lowercase, digits and special characters).

Pas d'IPv6, je survivrai.

Le problème de configuration DNS est normal, je n'ai pas encore mis à jour la zone DNS.

Je me suis connecté sur l'interface web pour créer un certificat pour mon domaine principal.

===== Installer une application =====

=== Nextcloud ===
J'ai essayé d'installer [[nextcloud]] (que j'aimerais beaucoup migrer sur Yunohost pour me simplifier la vie...) mais ça coince. ([[https://paste.yunohost.org/raw/ucihoguriw|https://paste.yunohost.org/raw/ucihoguriw]])
