VNC connection to Wayland / PipeWire aborts

[André Colomb]

Connecting to a modern installation of Ubuntu 21.10 Impish Indri using the Wayland display server (and PipeWire / gnome-remote-desktop) does not work from the current LTS release 20.04 Focal Fossa. It aborts immediately after authentication.

The bug appears directly related to the version 1.4.2 in focal, as building the up-to-date remmina version 1.4.23 package (from jammy) under focal does not exhibit the faulty behavior. Since future versions of Ubuntu itself will likely stick with Wayland and therefore cannot be used with Remmina from the LTS release anymore, I think an SRU might be in order.

As a workaround, other VNC viewers such as Vinagre are able to connect to the same server under focal.
