### Description of my issue
The update form Mastodon 4.2.8~ynh1 to 4.2.10~ynh1 failed.
Possibly a similar problem to this one: [https://forum.yunohost.org/t/mastodon-4-2-8-update-fails-because-of-missing-db/29886](https://forum.yunohost.org/t/mastodon-4-2-8-update-fails-because-of-missing-db/29886)

I have exactly the same problem with a vps. the update does not work via the yunohost webadmin, as well as via ssh with screen:
Variable $redis\_namespace wasn’t initialized when trying to replace **REDIS\_NAMESPACE** in /var/www/mastodon/live/.env.production.
It probably has something to do with the “redis namespace”.

Super hacky solution to test (make a full backup first!):
```sh
sudo yunohost app upgrade mastodon -u https://github.com/YunoHost-Apps/mastodon_ynh/tree/orhtej2-patch-1
```
