2.0.4 Interface "modMediaSourceInterface" not found on MODX 3.1.2

Open charismeki opened this issue 4 months ago • 6 comments

Hi tthere,

when trying to update Gallery from 2.0.3 > 2.0.4 the package could not be installed on several of webpages we are taking care of. The error is

Installation not possible with Error in /core/components/gallery/model/gallery/galleryalbumsmediasource.class.php:5: Interface "modMediaSourceInterface" not found "gallery-2.0.4-pl" not possible to install.

How to troubleshoot this issue? Permissions and Ownership is ok. I have fully removed the Gallery Plugin files from the hosting but have left the database untouched. I found https://community.modx.com/t/upgrade-2-8-7-to-3-0-5-uncaught-error-interface-modmediasourceinterface-not-found/7827 but I do not have a Gallery Media Source at Media Sources.

The system is running on LAMP stack with PHP 8.3.

Any ideas on this?

Many thanks and kind regards

Does an entry exist in the system setting extension_packages for "gallery"? If so, try to remove the "gallery" entry from this setting and check if that fixes the issue.

no the only entry in table system_settings for extension_packages is "system"

sry not correct taking a look via system settings over the backend the value is [] In systems where the update was possible I have the same entry like in the ones where it is not possible

And you are sure that there exist no media sources of type "Gallery Albums"? Database table modx_media_sources -> column "class_key" = GalleryAlbumsMediaSource or Gallery\Model\GalleryAlbumsMediaSource?

I wasn't able to reproduce any issues when testing this update myself. I also don't see why the file /core/components/gallery/model/gallery/galleryalbumsmediasource.class.php would even be used in MODX 3 (especially on upgrading the extra). This file is only for MODX 2 and was replaced with core/components/gallery/src/Model/GalleryAlbumsMediaSource.php for MODX 3.

  • Did Gallery version 2.0.3 work correctly on MODX 3 before the update?
  • Is this an older site that was upgraded from MODX 2 to 3?

Indeed in modx_media_sources I found a GallerySource. I removed it and voila installed 2.0.4 on one of the sites. Many thanks for pointing me to this. In case I do not comment any further this will do the trick with all other sites. Have a nice weekend!

PS: Yes 2.0.3 was working correctly and I was able to downgrade / to remove the not installed 2.0.4 Yes updated from MODX 2 > 3
