X11 connection rejected

[Patrick Dupre]

Hello,

On a machine I can ssh -X and run xclock for example, but
 sudo system-config-users
gives

(process:5034): Gtk-WARNING **: 14:59:07.212: Locale not supported by C library.
    Using the fallback 'C' locale.
X11 connection rejected because of wrong authentication.
system-config-users requires a currently running X server.
GtkWarning: 'could not open display'

Is there a solution?

Thanks

1.  system-config-users already has it's own method to elevate privilege, so 
no need for sudo

2.  ssh root@host system-config-users

Either become a maintainer and fix system-config-users find another GUI
tool.

bugzilla https://bugzilla.redhat.com/show_bug.cgi?id=1778407 says:

This package was removed from Fedora [31] as there was no active
maintainer and the code failed to build (bug 1676111
https://bugzilla.redhat.com/show_bug.cgi?id=1676111).

If you like to see this package in Fedora please consider becoming a
Fedora maintainer. See
https://fedoraproject.org/wiki/Orphaned_package_that_need_new_maintainers#Cl...
for further information.

For decades I have been using simple scripts calling commnd-line tools
(e.g., useradd on Fedora 31)
with arguments customized for the user id's, groups, etc. defined for a
particular site.   This has worked
for me on Sun, SGI, NeXT, RHEL, Debian, Gentoo, Fedora, Ubunto, Mint, and
others.

Seriously, you need to supply more information than you've revealed thus far.

What version of Fedora are you running on the system you which to ssh to?

Can you do the most basic?  "ssh root@192.168.14.154"  ?

If you are logged into the 192.168.14.154 can you "su -"?

I did not create any root on this machine. Do I need to do it?
All root connections fail (from he machine of from remote).

I believe that starting with the installed of Fedora Workstation F30 the root account is
created but disabled.  There is no root password.

So, you have to login to the system with the account you've designated as an administrator
and then give it a password.  I think, based on what you've said, that account is pdupre.

So.....

ssh pdupre@whateverhost

then

sudo passwd root

[Patrick Dupre]

I tried to log in root with my passwd (administrator), but without
success. I will try again.

That isn't what I suggested you do.....

I indicated you should login as yourself.  Then "sudo passwd root" to give the root user account
a password.

Then to test do "su -" to become root.
