For Debian 11, The XRDP package results in an error.

The problem seems to happens only with Gnome Desktop. We have tested the same setup but with KDE desktop and everything is working as expected.

Based the the bug/issue reported to the team behind xrdp software (see, the problem is only present when using the xorgxrdp package version 0.2.12. Previous version of Debian (Debian 10) was using the package version 0.2.9 and we didn’t encountered the issue…Debian 11 is shipping with the problematic version (i.e. 0.2.12) and this explain why the connection is failing.

The only fix proposed by xRDP team is basically to upgrade the xorgxrdp package to a more recent version which is exactly what’s happening when you are performing the custom installation….

So lets remove xrdp if installed.

Fix: Authentication Required Prompt

On some desktop environments, some nagging prompts require additional authentication.

You can dismiss them and continue the session without it popping up again, but that is a temporary fix, as it will pop up later.

Debian uses a framework called Polkit, which handles application authorization. It captures actions that the user is attempting to perform and checks if they are authorized or if they aren’t and need to authenticate for them to be authorized. Polkit reads some policy files to determine this.

What we’ll do is create such a policy file ourselves.

Create and edit the file with your preferred text editor.

$ sudo nano /etc/polkit-1/localauthority.conf.d/02-allow-colord.conf

And paste the following:

polkit.addRule(function(action, subject) {
 if (( == "org.freedesktop.color-manager.create-device" || == "org.freedesktop.color-manager.create-profile" || == "org.freedesktop.color-manager.delete-device" || == "org.freedesktop.color-manager.delete-profile" || == "org.freedesktop.color-manager.modify-device" || == "org.freedesktop.color-manager.modify-profile" || == "org.freedesktop.packagekit.system-sources-refresh" || == "org.freedesktop.packagekit.system-network-proxy-configure") &&
 subject.isInGroup("{users}")) {
 return polkit.Result.YES;
