Public bug reported:
I'm running Ubuntu 20.04 on my desktop. I SSH into my laptop running
22.04:
desktop$ ssh laptop
laptop$ sudo -sE
laptop#
If I now run most any X11 client applications (e.g. xload, xterm)
using this laptop SSH command line, they correctly open windows on my
desktop X11 display, not on my laptop, using the DISPLAY variable set
to localhost:10.0. But ubuntu-bug does not do this when I run it on
the laptop:
laptop# ubuntu-bug /etc/network/if-up.d/resolved
At this point, the laptop display incorrectly has the apport X11 window
open. The apport window does not open on my desktop, like any other
X11 application would. It appears to ignore my DISPLAY variable.
If I go over to the laptop and try to continue with the bug report,
everything falls apart when it tries to start up a web browser. I get
all these error messages on my SSH terminal screen:
update.go:85: cannot change mount namespace according to change mount

If ubuntu-bug cannot work over SSH with DISPLAY=localhost:10.0, it should
detect this and not even try.
