Auto-update from 15.0.2 to 15.0.4 failed

Nextcloud version : 15.0.2
Operating system and version : Linux
Apache or nginx version : Apache 2.4.37
PHP version : 7.1.25

The issue you are facing:
While trying to update through the auto-updater on 2019-02-07 @ 21h30, the operation failed at step « Move new files in place » with error « Parsing response failed. ».

As « Delete old files » step is previously executed, no files are left exept for datas and configs. There is hence no Nextcloud log available.

Is this the first time you’ve seen this error? : Yes, in this way, althought it’s not the first time I have an error while updating next/owncloud. In fact, I’ve never been able…!

Steps to replicate it:

  1. Have Nextcloud 15.0.2
  2. Update to 15.0.4 trough admin panel’s auto updater
  3. FAIL at step

The output of your Nextcloud log in Admin > Logging: NONE

The output of your config.php file in /path/to/nextcloud :
