Can’t wait ! But I can wait ! 
OK, so, now that your admin panel is back, let’s use it.
Go to “Backup”, “Local archives”, and then look for a backup named nextcloud-pre-upgradeX, by the way checked the dates and try with the more recent one.
Restore this backup and see if it’s work.
Hello !
When I click on “Local Archives” it stucks for few minutes and returns :

By the command line I found a pre-upgrade archive .tar.gz and a pre-upgrade .info.json.
What’s next ? Do I need to fix backup tool in the first place ?
Could you show me what gives sudo ls -alh /home/yunohost.backup/archives/ ?

About nextcloud, you have a backup from yesterday morning, that’s the one from your upgrade.
Try to restore this one, should probably be ok now.
sudo yunohost backup restore nextcloud-pre-upgrade2 --force
Do you think I need to make a copy of
/home/yunohost.app/nextcloud/data
before trying to restore ?
It shouln’t be affected, but you can if you want.
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 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 !
First, be careful because each upgrade will remove a backup and create a new one.
So copy your backups in another directory to be able to restore them anyway.
Then, the backup was before the upgrade, so that’s your old version. Means you still have to upgrade. Except that was expecting it to work this time…
If your admin panel is still working, go to “Tools”, “Logs”, and look for the log of nextcloud’s upgrade.
If not, try in /var/log/yunohost/.
Also, you can check the nginx log, /var/log/DOMAIN.TLD-error.log
I understand, I’ll be careful…

Looks like that’s because of this plugin, after a restoration of your “old” nextcloud, try to remove this plugin, either from the panel, if it works or by removing its directory.

Yes !!!
It works !
I saw the files_pdfviewer error but I had no idea about uninstall or fix the bug…
I ran
sudo rm -rf /var/www/nextcloud/apps/files_pdfviewer/
to remove the app directory and relaunched a successful upgrade.
Thank you so much @Maniack_Crudelis and @Sango for your time, I fixed my problem and learned a lot !

Hi there !
I want to mention that this helps me to backup/restore my nextcloud instance 
I have the same issue, and disabling PDF viewer solved the same problem.
Thanks guys !
