Copy to clipboard not working on Ubuntu

[Patch]

@Mule1

The server version can copy to clipboard in browser quite alright but only on the computer adopted as a server

although the symptoms are similar this is a different problem to that being discussed in this thread. See

Bug with "Copy to Clipboard"

Clipboard API which Manager is using works in modern web-browsers only when page is served through https protocol. The only exception is when running server edition locally and accessing Manager through localhost. This is why the issue is not on desktop edition (it’s always localhost access) or cloud edition where https protocol is enforced.

You have to provide https access for all server installations not just publicly accessible servers. See this post for how to do it Bug with "Copy to Clipboard" - #69 by Patch
