Spreed: Cannot declare class OCA\Talk\Migration\Version2000Date20170707093535

✅ Solution

We were only able to solve this in Nextcloud Server 19 onwards. So the major update from Nextcloud 17 to 18 will always trigger this.

🚧 Workaround

Uninstall the app and install it again.

Original Post by @NeutroGe

Steps to reproduce

Install a fresh nextcloud 18.0.0.10 (latest current version)
Try to install Talk app
Check errors in nextcloud logs

do you have the spreed in multiple apps/ folders?

👍1

[root@nextcloud nextcloud]# find /var/www/html -name "spreed"
/var/www/html/nextcloud/apps/spreed
[root@nextcloud nextcloud]#

If that's what you meant :)

I've tried again today based on a user reply on nextcloud community forum and found out that it's not a blocking error.

When you install talk, even when there is no spreed folder in the app folder you still get that error, but after getting it you can still press the "activate" button and the app works.

NeutroGe on 22 Jan 2020

Thats even more weird, but okay thanks :)

Hi, On new NC18 I have the same problem, it needed to push 3 times the Download and Enable button to make something and then I refresh the page and it appear on Disabled apps category, and at finish it need enabled.

Same issue here on a fresh NC 18 installation. There is already an apps/spreed folder but I never installed talk/spreed manually. Maybe it is part of the recommended apps that are installed when the option is set on first run. Ok. Whatever. Let's get rid of it...

sudo -u www-data ./occ app:remove spreed

Removal is successful and the folder apps/spreed has vanished. Let's install it again...

sudo -u www-data ./occ app:install spreed
...
PHP Fatal error: Cannot declare class OCA\Talk\Migration\Version2000Date20170707093535, because the name is already in use in /var/www/html/nextcloud/apps/spreed/lib/Migration/Version2000Date20170707093535.php on line 127

Computer says no. Also, the web interface still shows 'download and enable'.

And now comes the weird part. Hitting 'download and enable' in the web interface again finally enabled Talk. So, somehow it works but there is definitely something wrong.

Similar experience on a fresh NC18 install.

Managed to reproduce now

Just tried this on a fresh 18.0.2 install via docker, still seeing the same error:

php occ app:install spreed
PHP Fatal error:  Cannot declare class OCA\Talk\Migration\Version2000Date20170707093535, because the name is already in use in /var/www/html/custom_apps/spreed/lib/Migration/Version2000Date20170707093535.php on line 127

Just tried this on a fresh 18.0.2 install via docker, still seeing the same error:
Me too. Same error.

php occ app:install spreed
PHP Fatal error:  Cannot declare class OCA\Talk\Migration\Version2000Date20170707093535, because the name is already in use in /var/www/html/custom_apps/spreed/lib/Migration/Version2000Date20170707093535.php on line 127

Arg... Docker has a custom app path setup?

nickvergessen on 16 Mar 2020

I installed this on a fresh 18.0.2 install, no docker, still seeing the same error:
PHP Fatal error: Cannot declare class OCATalkMigrationVersion2000Date20170707093535, because the name is already in use in /var/www/html/custom_apps/spreed/lib/Migration/Version2000Date20170707093535.php on line 127

rubenszolt on 16 Mar 2020

I must mention that I'm also not using docker and have exact same issue.

daleosm on 16 Mar 2020

This is in the Nextcloud VM as well, which is vanilla Nextcloud. Installing Talk via occ

enoch85 on 17 Mar 2020

Well custom_apps is not vanilla and exactly the tripping point here. But I put it back on my list

nickvergessen on 17 Mar 2020

I just had the same error in a docker instance. I _docker execed_ into the container and moved the _spreed_ folder from _custom_apps_ to _apps_ and I'm now seeing Talk inside Nextcloud.

After deactivating and removing the app via Nextcloud and then removing the _apps/spreed_ folder inside the container, I could reinstall the app without problems.

_Talk_ was reinstalled in _custom_apps_ and seems to work.

hacktrick on 17 Mar 2020

custom_apps

I always thought Talk was "default" a Nextcloud app, I stand corrected.

enoch85 on 17 Mar 2020

Currently no further comments are needed, so I lock this issue for now.

For completness:

The issue has been reported on the forums as well: https://help.nextcloud.com/t/cannot-install-talk-on-fresh-nextcloud-18-install/68613
I faced the same with current stable NC18.0.4 on a fresh install when doing: occ app:install spreed
Will test with current beta (19 beta5)... EDIT: Fixed with #19433 since error does not appear anymore, although I needed to "enable untested app". Will mark this issue as closed.
