### My YunoHost server
**Hardware:** Computer with VM by Proxmox
**YunoHost version:** 11.2.11.3 (stable) with updated packages system the same day.
**I have access to my server :** Through SSH & through the webadmin & direct access via keyboard / screen
**Are you in a special context or did you perform some particular tweaking on your YunoHost instance ?** : yes
Only adapted the Nginx for logs and works behind a Proxy SNI
### Description of my issue
NextCloud previously worked on this server.
Yesterday, I updated it, but can’t log in (Means php working).
Because it was for tests, I removed it, and reinstalled it, but the the installation failled.
In the log, I saw that was a MySQL issue.
I restarter the server (easyer than connect to SSH at this time), but same problem, can’t install NextCloud.
Logs are here: [https://paste.yunohost.org/raw/padagaleco](https://paste.yunohost.org/raw/padagaleco)
I checked, in the MySQL, there is no Nextcloud users, and no databases for nextcloud.
Here, some parts form logs.

### Mon serveur YunoHost
**Matériel:** ordinateur avec des VM par Proxmox
**Version de YunoHost:** 11.2.11.3 (stable) avec mise Ă jour des paquets le mĂŞme jour
**J’ai accès à mon serveur :** En SSH & webadmin & En direct avec un clavier/écran
**Êtes-vous dans un contexte particulier ou avez-vous effectué des modificiations particulières sur votre instance ?** : oui
J’ai modifié un peu Nginx pour les logs et de manière à ce que tout fonctionne parce que la VM est après un Proxy SNI
### Description du problème
NextCloud a déjà fonctionné par le passé sur cette installation.
J’ai mis à jour NextCloud, mais après je n’ai pas réussi à m’identifier, mais je n’ai pas trop fait attention.
Comme c’était une installation de test, je l’ai désinstallé et réinstallé.
Mais l’installation à échoué.
J’ai vu que c’était une erreur MySQL, dans le doute, j’ai rebooté la VM (plus facile que de voir par SSH).
Cela n’a rien changé, l’installation échoua encore, avec cette erreur MySQL.

Bonne journée

I tried the version 29 from the git repository, and the installation was successful, and NextCloud working.

Today, on another server, I installed NextCloud, without problem.
I will need to investigate why I have problems on another server (and will try to answers to [Désinstallation de Nextcloud à la dernière mise à jour](https://forum.yunohost.org/t/desinstallation-de-nextcloud-a-la-derniere-mise-a-jour/29493/1) )

Strange, everything works now.
I can’t reproduce.
