Summary of the issue you are facing:
For a few days now, I’ve been trying to update my Nextcloud instance from version 31.0.2 to version 31.0.4. Unfortunately, the update fails every time at the “Verifying integrity” step with the error message “Parsing response failed.”
I’ve successfully performed several Nextcloud updates in the past. Even restoring the full installation didn’t resolve the issue.
Steps to replicate it (hint: details matter!):
Log entries
Nextcloud
Please provide the log entries from your Nextcloud log that are generated during the time of problem (via the Copy raw option from Administration settings->Logging screen or from your nextcloud.log located in your data directory). Feel free to use a pastebin/gist service if necessary.
PASTE HERE
Web Browser
If the problem is related to the Web interface, open your browser inspector Console and Network tabs while refreshing (reloading) and reproducing the problem. Provide any relevant output/errors here that appear.
PASTE
Web server / Reverse Proxy
The output of your Apache/nginx/system log in /var/log/____:
PASTE HERE
Configuration
Nextcloud
The output of occ config:list system or similar is best, but, if not possible, the contents of your config.php file from /path/to/nextcloud is fine (make sure to remove any identifiable information!):
PASTE HERE
Apps
The output of occ app:list (if possible).
Tips for increasing the likelihood of a response
- Use the
preformatted textformatting option in the editor for all log entries and configuration output. - If screenshots are useful, feel free to include them.
- If possible, also include key error output in text form so it can be searched for.
- Try to edit log output only minimally (if at all) so that it can be ran through analyzers / formatters by those trying to help you.
