---------------------------------------------------------------------

I created a new Ubuntu 18.04 VM, updated and installed Guacamole from scratch 
(with freerdp2-dev at version 2.1.1).

Connecting to my Win7 instance I get the same colour issues, although I don't 
get disconnected [see update below].

I see the problem appears to occur in Ubuntu 20.04, and a ticket has been 
lodged with the freerdp team:

[https://github.com/FreeRDP/FreeRDP/issues/6258]

Unlike me that person appears to be getting disconnected from Win7. They don't 
disclose if they have any colour issues.

UPDATE:

I always set connections to 32-bit colour.

I've found that if I set the connection to have no setting, or 24-bit, the 
colour issue resolves itself.

Apologies that I don't seem to be able to replicate the disconnection problem 
in my test environment. Thus I cannot comment if this would have any affect on 
connections, however I suspect not given no-one else appears to have commented 
on the colour issue. Therefore it may be a red  (orange) herring, albeit 
annoying?

> Hello,
>  
> A recent update to the freerdp2-dev (2.1.1) package on Ubuntu has broken the 
> Guacamole compatibilty.
> RDP connection is instantly closed without any error message.
> I had to downgrade to 2.0.0 to make it work again.
>  
> Not sure if this should be there, but, as you advice to install this package 
> in your doc, I think, you should be aware of it.
