Update from 10.14.0 to 10.15.0 fails

Hello,

I have two separate and different OwnCloud installations with the same provider.
I can no longer perform updates, even though I really need to because of the issue where portrait-mode photographs are not displayed, which is fixed in the latest version (10.15.0). Below is the error message I receive, but it doesn’t explain much to me.

I tried the update with the method given in:
“Parameters” and “Mises à jour”
Une nouvelle version est disponible : ownCloud 10.15.0
Canal de mise à jour :
Vous pouvez à tout moment mettre à jour vers une version plus récente ou un canal expérimental. Cependant vous ne pourrez jamais revenir à un canal plus stable.

Could you provide a solution to this problem?

Error message:
Client error: POST //localhost/owncloud/index.php/occ/config:list resulted in a 404 Not Found response: <?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE html PUBLIC “-//W3C//DTD XHTML 1.0 Strict//EN” ".w3.org/TR/ (truncated…)

Many thanks!
Jean-Claude

Hey,

i’m not sure as the info is not missing but i think it could be possible that you are using the updater app? If this is the case from what i have read in the past this is not the recommended way of updating ownCloud. I think the recommended way of updating is to do a manual update like explained by the ownCloud people here:

Many thanks for your answer, Tom42
Yes, I did it with the updater!
Until now it worked very well but this time not.
Why does this update option exist?
Any idea about the error message I posted?
For me the manual update as described seems too complicated for a non-expert!
I don’t know what to do?
