Failed to install Plex

I tried to uninstall the Tronder88 plex version to get the new official one. But i get this error message
"
Error!

Errors occurred while processing updates for following Rock-ons. Plex: Cannot add/remove volume definitions of the container(plex-linuxserver.io) as it belongs to an installed Rock-on(Plex). Uninstall it first and try again.
"

What should I do? I cant see that I have any installed rock-ons at all?

@KaiHai you may have also a look into these posts and try maybe also the testing updates instead of stable.

Hi,
Thanks for the tip, but after deleting the rock-on-root folder and setting it ut again it all worked fine so sticking to the stables for now:)
