I was using https://github.com/appsembler/xblock-video on lilac and it was working fine.
I am trying my xblock installation with the latest quince release.
But on installing the video_xblock, gives the following error

Can someone please tell me, why this is happening?

How did you install the xblock? If you have it as a file in a forked repo make sure you update that file to the latest version supported by quince. Also note that quince changed the way it install extra plugins and xblocks as can be seen in their release notes now.

I copied it into my docker containers and pip installed it.
That is the standard way, as per my knowledge.

There is nothing that needs changing as far as xblocks are concerned i think, as i do have some xblocks that ran fine with v12 lilac, and run fine in v17 quince too.
I suspect the problem is with appsembler’s xblock-video fork and its compatibility with quince release.

Though what you said about the plugins, i will look into that.
Thanks :slight_smile:
