New plex server update wont work

They released the new server update, and when I try to install it on my QNAP, it won’t work; the older files show an error: unable to install package. I never had issues with the older ones until the new release update today wont work

A quick search would have revealed that this has been discussed several times already in this forum but, essentially, you need to install it unsigned for now.

It’s mentioned on the downloads page here and instructions on how to install are here.
