Can't install MediaWiki on new ynh instance

My YunoHost server

Hardware: Hetzner cloud
YunoHost version: 11.0.11
I have access to my server : both
Are you in a special context or did you perform some particular tweaking on your YunoHost instance ? : no
If your request is related to an app, specify its name and version: MediaWiki 1.39.0~ynh1

Description of my issue

Install script gives this error: https://paste.yunohost.org/raw/eyozodeduj

Is there any way to get notified when MediaWiki is working again?
