@deimjons Do you have viewer and serverinfo apps installed and enabled? Did you installed and enabled cloud_py_api first, then mediadc?

[deimjons]

Thanks for the ideas on what I need to check. Now it is working well for me. Looks like serverinfo was disabled. Please add some information to cloud_py_api documentation/description that serverinfo and viewer required.

Information for the people who will have similar problem:

You need to check that these two default apps are enabled.
https://github.com/nextcloud/serverinfo
https://github.com/nextcloud/viewer

In my case, I didn't see these apps in nextcloud UI. Not in enabled, not in disabled. Maybe they have a different name in UI - I don't know.
I just enable both with OSS command app:enable. In my case, serverinfo was disabled.

1. I uninstalled mediaDC and cloud_py_api.
2. Then enable serverinfo via OSS command app:enable serverinfo . (same with viewer)
3. After that I installed cloud_py_api. It started to work.
4. And the last step, I installed mediadc (installation take some time).

I'm experiencing the same thing, except I already have the serverinfo and viewer apps enabled.

I see the following error in the logs:

Exception: Repair step 'OCA\Cloud_Py_API\Migration\AppDataInitializationStep' can't be instantiated: Could not resolve OCA\Cloud_Py_API\Service\UtilsService! Class "OCA\Cloud_Py_API\Service\UtilsService" does not exist

Some info:
OS [Docker nextcloud aio official image]
CPU [architecture x86]
Nextcloud version [26.0.2 RC1]
Database configuration (default aio config)
app version, that using cloud_py_api: N/A
cloud_py_api version [0.1.7]

i am getting the exact same problem.
(i was on the latest aio version, then updated to beta, still same results)

[Arbel-arad]

i figured out the solution.
there was a folder left from when i first tried to install mediaDC
/mnt/ncdata/appdata_oc5bwmghpu5h/mediadc
after deleting that and installing cloud python api again the settings page shows up!

[TheSimpleZ]

I also got it working. I did not fiddle with any folders. Simply update to the latest version (0.1.8)

[Arbel-arad]

it doesn't seem like the update works with the brokenfolder still in place.
anyway it's good that you got it working.

I also had an issue with installing cloud_py_api and mediadc and resolved it by deleting false entries in my database due to what i think was a migration error on one of the last updates. I explained the steps i took in detail here.

[weasam]

I also had this problem on nextcloud 27.0.0

I followed along with another post trying to fix it by delete some config of MediaDC, but don't do this
------WARNING!!! DON'T DO THIS BELOW-----
I Wrongly deleted the database
oc_mediadc_photos, oc_mediadc_settings, oc_mediadc_tasks, oc_mediadc_tasks_details, oc_mediadc_videos table in database, and cloud_py_api in oc_appconfig table in database
It will bring you and error
OC\DB\Exceptions\DbalException: An exception occurred while executing a query: SQLSTATE[42S02]: Base table or view not found: 1146 Table 'weasam_ncloud2.oc_mediadc_tasks' doesn't exist
------WARNING!!! DON'T DO THIS ABOVE-----

install cloud_py_api first then install MediaDC
Fortunately I copy the table from another newly installed nextcloud instance, keep in mind to backup your database first

[cuthulino]

I get the following Exception when installing cloud-py:
Exception: Repair step 'OCA\Cloud_Py_API\Migration\AppUpdateStep' can't be instantiated: Could not resolve OCA\ServerInfo\DatabaseStatistics! Class "OCA\ServerInfo\DatabaseStatistics" does not exist

(serverinfo app enabled)

[weasam]

I have new instance installed, MediaDC installation issue come up again. After I enable some php function in php.ini, it install successfully, because my HestiaCP panel disable some php function by default

php.ini
