Summary of the issue you are facing:
After upgrading my (many years old at this point) instance to NC 32 I can install, but cannot enable apps with the web interface. I can enable them with the OCC CLI. When trying to enable any apps with the GUI I get a notification message:
Error: This app cannot be enabled because it makes the server unstable
Despite the fact the apps work fine when using OCC to manually enable them. This also happens when I disable an app that’s already installed and working, then try to re-enable it.
I also have a new error I’ve never seen before in the Nextcloud Overview labeled “AppAPI Deploy Daemon” with the message:
AppAPI default deploy daemon is not set. Please register a default deploy daemon in the settings to install External Apps (Ex-Apps).
I’m guessing, though not totally certain, that the inability to enable apps in the GUI is somehow related to this, but I have never had to mess with AppAPI before and am unsure what requirements I need to meet to solve this error and be able to manage my apps via the GUI again. I found some guidance here:
Which recommends this:
But despite the recommended docker image launching successfully, Nextcloud seems unable to connect to it. Since I’ve used Docker “very” little in the past and haven’t seen this issue before, I’m sure I’m just missing something, I just don’t know what exactly. Is “docker-socket-proxy” supposed to connect to something else, like the Nextcloud instance or database, or some other piece of software? Do I need to configure it before launching it? The instructions on the page for it don’t have much other than how to get it running, but not really how to get it and Nextcloud to talk to one another, and I’m sure manually editing files related to it in /var/lib/docker is not the correct way forward.
Steps to replicate it (hint: details matter!):
-
Be running Nextcloud 31.x via a manual install
-
Upgrade to NC 32
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!):
