Webtrees update fails with: username: unbound variable

[chmeyer]

My YunoHost server

Hardware: VPS bought online
YunoHost version: 11.2.27 (stable)
I have access to my server : Through SSH | through the webadmin
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: Webtrees 2.1.18~ynh2 → 2.1.20~ynh1

Description of my issue

I’m trying to update webtrees 2.1.18~ynh2 → 2.1.20~ynh1 and I’m getting an error in ./upgrade: line 17: username: unbound variable.

Full log is https://paste.yunohost.org/raw/fefefaxuto .

/etc/php/8.2/fpm/pool.d/webtrees.conf exists,
/etc/php/8.2/fpm/conf.d/20-webtrees.ini does not.

I don’t see any hint to a variable named username, configfile only mentions user = webtrees.

Thanks a lot,
Christian
