How to Fix “Authentication is required to create a color profile/managed device”

The safest fix to get rid of these popups is to create a new configuration file in /etc/polkit-1/localauthority/50-local.d/45-allow-colord.pkla.

sudo nano /etc/polkit-1/localauthority/50-local.d/45-allow-colord.pkla

Paste in the following:

/etc/polkit-1/localauthority/50-local.d/45-allow-colord.pkla

[Allow Colord all Users]
Identity=unix-user:*
Action=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
ResultAny=no
ResultInactive=no
ResultActive=yes

Save and exit (press CTRL + X, press Y and then press ENTER)

This tells Polkit to continue without requiring the authentication prompt over RDP.

Now reboot Ubuntu and try logging in again over RDP / Windows Remote Desktop and the popups should be gone.
