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!):

How do I get that from the Snap?

Apps

The output of occ app:list (if possible).

How do I get that from the Snap?

I’m sure there’s more relevant info I can provide, and with guidance on what’s useful I’ll do my best. Thanks in advance for any help on this.

Related question: if all else fails, is there a way to export all app data from an Nextcloud instance so I could install a fresh snap and restore all the users, apps, and the user data for those apps?

I have plenty of copies of the Files repository, but the DB stuff is what I’m concerned about mostly.

In this case, things ran great for many months, but after a recent update the Calendar app icon was no longer rendering in the tool bar, and clicking it didn’t load the app, just refreshed whatever page I was on.

Then I rolled back to a previous snap, and while it restored Calendar I’m now finding I can’t add/remove/update apps.

Whether or not I fix this, it would be nice to find a solution for backing up user app data.

UPDATE: Since I wrote that I’ve found the Export command. Tasty.

I chose the Snap because I don’t need flexibility but I do need minimal tinkering. And most of the time it delivers.

If a solution for the current mystery with apps doesn’t come to mind, any downside to using export, tossing the Snap,but a fresh Snap in place, and then re-importing?

scubamuc · June 2, 2026, 6:41am

@RGaskin, there are no mysteries, just too little information…

sudo nextcloud.occ config:list

you’re not giving us the information we need. so run the the debugging script and post the result here.

correct, if you’re referring to this Backup, restore & migrate wiki.

nope, but be patient and give us some information to be able to help you… worst case would be you’re migrating the issue to your new instance…

scubamuc · June 2, 2026, 7:15am

@RGaskin thanks for those logs… its not nearly enough and I’m guessing here, but you may have tried to share something via ferderated share and the share is not reaching the federated instance… check your shares and check federated sharing in your admin interface, remove the broken federated share and try try again if that resolves your issue.

scubamuc · June 2, 2026, 8:30am

@RGaskin please run the following commands in the host shell and simply copy and paste the results here:

list installed apps

sudo nextcloud.occ app:list

show configuretion file (redacted)

sudo nextcloud.occ config:list

That output appears to include a private key. I can edit that, but should I be on the lookout for other details best left unposted?

RGaskin · June 2, 2026, 9:40am

But ah, there’s so much. Hard to know exactly what you’re looking for without risking overloading you with MBs of junk that isn’t useful to you.

I don’t have federation enabled, and am not sharing with any other instances.

I did install the Jira integration, but haven’t yet had time to set that up.

Hey @RGaskin don’t hassle, that app list was a great help… there are a couple of apps you should deisable/remove, as they are unsupported and could be the source of your issue:

compatipility issues probable

app_api: 32.0.0
context_chat: 5.3.1
doom_nextcloud: 1.0.8
drawio: 4.1.4
files_zip: 2.3.0
integration_jira: 1.4.1
side_menu: 5.3.0

ARM64 issues

richdocuments: 9.0.6
richdocumentscode: 25.4.904
see How to install Collabora built-in CODE server on Nextcloud snap

A prevalent cause of auto-update issues is attributed to incompatible third party apps due to snap confinement. Any apps requiring access to executable binaries will cause auto-updates to fail since these are not included in the snap. Disabling the misbehaving apps usually resolves the auto-update issue. Sometimes apps can be re-installed or re-enabled after successful manual refresh (update)… but may recur during the next auto-update.

see Managing automatic update issues

Disable apps using the commandline (shell on host)

If your Nextcloud interface is unavailable or in Maintenance mode, you can disable apps using the management console or command line:

List apps: sudo nextcloud.occ app:list
Disable app: sudo nextcloud.occ app:disable <appname>
- Remove app: sudo nextcloud.occ app:remove <appname>

Note: you’ll need to disable those apps listed one by one using the <appname> (without version numbers!)

e.g. sudo nextcloud.occ app:disable app_api or sudo nextcloud.occ app:disable context_chat

recommendation

try not to collect all sorts of fancy apps because they sound interesting/fun, as some of these apps are third party apps and the maintainers are slow updating them sometimes and the snap is rather opinionated about third party binaries… its a security measure after all.

Thank you for the tips. I’ve been taking too much for granted with regard to app stability, but given the combinatorial explosion of possibilities it makes sense to drop all but the essentials (most were evaluating things for clients, except Doom, because, well, Doom).

All those you’ve listed have been removed. Dropped Cookbook while I was at it.

After restarting for freshness, the situation with not being able to enable/disable/remove apps remains, but with a new twist.

Now in the Admin Overview’s “Security Check” I see something I’ve never seen before:

“Code integrity
Some files have not passed the integrity check.”

When I click the provided link to review the details, I get:

The part about “Please read the previous linked documentation to learn more about the errors and how to fix them” is a head scratcher, as I’ve not seen that “previous link” - did I miss something obvious?

Thanks again for your help.

@RGaskin I’ll point you in the right direction → code integrity failure

that would be your notes app causing the integrity failure. so uninstall and reinstall the notes app.

RGaskin · June 2, 2026, 7:03pm

Now that you draw my attention to it, I do see a line referencing that app. How did you home in on it so quickly?

I’ll go remove/reinstall and report back…

Thanks again.

RGaskin · June 3, 2026, 12:38am

After removing and re-installing Notes, I get the same warning about the integrity check, with these details:

RGaskin · June 4, 2026, 4:21am

I just realized my last post with the log was a reply to myself, so you’d have no way to know I’d tried the uninstall/reinstall.

I appreciate your time and attention, whenever you’re free. Thanks for all you do for this Snap.

scubamuc · June 4, 2026, 5:22am

you’ll need to do it the dirty way and delete the listed app subdirectories .../l10n, .../lib, etc. manually as root after removing the app. it looks like some files are being left behind, which shouldn’t be there.

the Nextcloud integrity check literally tells you which files are causing check failure. deleting the listed files should be sane. you probably could delete the entire notes directory as it would be added upon re enabling the notes app, but step by step is safer right?

hope that helps

This thread has gotten a bit long, thanks to the diligent assistance from @scubamuc. But the issue is now resolved, so before the thread closes let me post a summary of outcomes and lessons learned for future readers:

The solution I chose was to simply migrate to a completely fresh install. The latest Snap has undergone some great new optimizations, and from time to time it’s useful to start fresh with any system. This was that time for me with this NC instance.

Contacts, calendar, files, and more moved easily using the app-specific options for that. The only remaining piece is putting my Collectives files back in place, but that app has unusual config needs and I’m confident I can sort that out.

As for how I got here, that seems a good lesson in the complexities of app framework ecosystems, and the benefits of keeping production and exploration separate.

This instance is my main workhorse running my back office, and given the range of consulting I’m asked to help with it became convenient to explore new apps in it during the course of my work.

But when we have such a rich app API as NC provides, the preconfigured settings in the Snap, and the relatively wild-west freedom afforded app designers within NC, from time to time we may see an edge case with some app configs affecting others in a particular sequence just specific enough to elude even thorough testing.

And that seems to be what I encountered here. I got a bit too excited trying out every new app, and along the way I accidentally stumbled into an edge case too rare to easily diagnose.

With my new fresh install, I’ll be sticking with just the apps I need to run my shop. And thanks to the convenience of the well-maintained Snap, I know it’ll always be keep current with new releases automatically.

Now I also maintain a separate NC instance elsewhere for demoing various exotica, a playground where I can check out anything I want without having to consider how it may affect my main install.

Kudos to the NC team, the Snap creators, and the maintainers of the NC Snap, for making it easy for me to confidently sling around instances, make backups, restore backups, and do migrations.

Nextcloud Snap is a truly great solution for individuals and small orgs who value the convenience it provides and don’t need the flexibility afforded by Docker or metal installs.
