Install add-on with zip file not possible about chorus HOT 5 OPEN

What do you mean by "installed Kodi as ppacket"?

Try installing Chorus via Kodi's repository:
Inside Kodi go to System -> Settings -> Add-ons -> Install from repository -> Web interface -> Chorus.

from chorus.

I refer to the line in your readme:

Or use the zip in this repo

from chorus.

Yes, I agree it should work, but installing from repository is easier and maintenance-free (as you get updates), so you're recommended to use that method

from chorus.

what this issue is about is that the zip package does not work, so you should either remove the line mentioning that you can install from the package or repair the package

from chorus.

So change the title to something more informative like "Broken zip file" or "Can't install add-on with zip file".

from chorus.
