After Update to 1.2.0-rcgit.29+dfsg-1ubuntu1.1 reconnection loop to xrdp-servers

Partly confirmed! Using Ubuntu 18.04 Server Package: xrdp Version: 0.9.5-2

When trying to connect without saved credentials I don't even get the login-screen from the server. It interrupts immediately and tries to reconnect.

The problem seems to live in libfreerdp2.2. Because if you don't upgrade libfreerdp with remmina, it just works fine.

looks like with this update there was a switch from freerdp1 to freerdp2 - and remminas support for freerdp in this "jurassic version" (as I've been told) is not (yet) working.

Using the ppa from remmina as suggested fixes the problem:

sudo apt-add-repository ppa:remmina-ppa-team/remmina-next
sudo apt update
sudo apt install remmina remmina-plugin-rdp remmina-plugin-secret

Version then:
#remmina --full-version

Remmina plugin glibsecret (type=Secret) has registered but not yet initialized/activated. Initialization order is 2000.
Secret plugin glibsecret has been successfully initialized and will be your default secret plugin

I have uploaded a remmina fix to the security team PPA here:

Once it has finished building, could someone please test it in their environment to see if it resolves the issue for them and comment back here?

I'll publish it once someone other than me has given it a try. Thanks!

Works like charm now!
