With the today packages upgrade, switching from X11 to wayland, synaptic refuse to load/open:

from the icon into the dash-to-dock, nothing happen
from the terminal:

sudo synaptic
[sudo] password for oem:
Invalid MIT-MAGIC-COOKIE-1 keyUnable to init server: Could not connect: Connection refused

(synaptic:2154): Gtk-WARNING **: cannot open display: :0

Previous days already have switching some packages to wayland, but synaptic was still working. Its only with the today upgrades, after a cold reboot, that synaptic gui is broken.
