I just explained it in my other post. It /is/ a magic cookie, and
X clients these days need that to talk to the X server. On my box,
for example:

No X server to talk to -> no GTK.

That would be another error message.

Whatever is happening, the synaptic thinks it is trying to do
Xorg. Perhaps it tries first wayland, fails and falls back to
X, thence the magic cookie thing.
But magic cookies are a thing, at least under X [1]
