I have the same reservations expressed by Glenn in emacs-devel, but this
would help me in the wrong way when emacsclient failed on me.

Seeing the message, I'll try this quick hack:

$ XDG_RUNTIME_DIR='/run/user/1000' emacsclient

and that probably would makes things "work".

A more educative message would be something like:

"The environment variable XDG_RUNTIME_DIR is not set and, since version
27, Emacs depends on it to communicate with the server. Usually this
variable is automatically set by the system at log-in. Check any
configuration that might affect how the environment is build when a user
logs-in."
