Getting help
In order to help you as efficiently (and quickly!) as possible, please fill in as much of the below requested information as you can.
Before clicking submit: Please check if your query is already addressed via the following resources:
- Official documentation (searchable and regularly updated)
- How to topics and FAQs
- Forum search
(Utilizing these existing resources is typically faster. It also helps reduce the load on our generous volunteers while elevating the signal to noise ratio of the forums otherwise arising from the same queries being posted repeatedly).
The Basics
- Nextcloud Server version (e.g., 29.x.x):
2.35.1
- Operating system and version (e.g., Ubuntu 24.04):
Kubuntu 25.04
- Web server and version (e.g, Apache 2.4.25):
2.4.65
- Reverse proxy and version _(e.g. nginx 1.27.2)
nginx
- PHP version (e.g, 8.3):
8.3.26
- Is this the first time you’ve seen this error? (Yes / No):
yes
- When did this problem seem to first start?
After distribution upgrade
- Installation method (e.g. AlO, NCP, Bare Metal/Archive, etc.)
AIO
- Are you using CloudfIare, mod_security, or similar? (Yes / No)
no
Summary of the issue you are facing:
After Distribution upgrade from 24.04 to 25.04, the entirety of the AIO stack seems to fail to boot due to the master container using an improper and outdated version of GuzzleHttp.
-
The
nextcloud-aio-nextcloudcontainer is stuck looping on “Waiting for OnlyOffice to become available” (despite OnlyOffice’s container being active.) -
nextcloud-aio-apacheis stuck looping on “Waiting for Nextcloud to start” -
The
nextcloud-aio-mastercontainerfails multiple times on a GuzzleHttp exception stating the client version 1.41 is too old and that the minimum supported Api version is 1.44. -
Logging in to (or attempting to do so) at FQDN:8080 yields a Slim Application Error on Login and yields the API version mismatch error.
Steps to replicate it (hint: details matter!):
-
Have latest NextCloud in a docker container on ubuntu 24.04.
-
Do a distro upgrade to 25.04.
-
Observe after reboot.

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!):
Is this supposed to be my config.json??
