**It worked !**  
_but…_  
Nextcloud returns a 502 Bad Gateway error…  
I restarted nginx, rebooted and diagnosis is ok…

So I looked for a solution and Yunohost GUI invited me to update Nextcloud.  
I tried again and same problem…

EDIT ------------  
Here the log for Nextcloud update :

```

```

END EDIT------------

I start again and now I have an old not working Nextcloud installation… In order to update I follow [your post](https://forum.yunohost.org/t/impossible-de-mettre-a-jour-nextcloud-aide/5230/18) but no `/temp` in my `fstab` configuration :

```
proc /proc proc defaults 0 0
/dev/mmcblk0p1 /boot vfat defaults 0 2
/dev/sda1 / ext4 defaults,noatime 0 1
# a swapfile is not a swap partition, no line here
# use dphys-swapfile swap[on|off] for that

```

What can I do for a proper update ?  
Thank you so much for your help !
