Problems updating from 14.04

Nextcloud version (14.0.4):
Operating system and version (Raspbian GNU/Linux 9 (stretch)):
Apache/2.4.25
PHP version: PHP 7.0.33-0+deb9u1 (cli)

The issue you are facing:

Trying to update via web-updater to v. 14.0.6 gives the error: “Verifying integrity
Parsing response failed. Step 5 is currently in process. Please reload this page later.”

When trying again, a white page is shown telling: “Step 5 is currently in process. Please reload this page later.”

When using updater on command line the error is: “[ ] Verify integrity …Ungültiger Maschinenbefehl” and after trying again also: “Step 5 is currently in process. Please call this command later.”

Is this the first time you’ve seen this error? (Y/N): Yes

Steps to replicate it:

  1. Update via web-updater or command line from v.14.0.4 to 14.0.6
