Comment 4 for bug 1034409

It is 2023 and ssh (x11 forward on in config) tmux and sudo -i before do-release-upgrade
still fills the log with `X11 connection rejected because of wrong authentication` errors.

`stderr` redirection (`2>/dev/null`) obviously is *not* an option.

Better do not trash message like this: `No space left on device` during an upgrade

User prompt appears in "curses" dialog. OK
