Preupgrade on Fedora-7

[Timothy Murphy]

I just resurrected an old computer running Fedora-7.
I ran "yum update" and it successfully updated 420 packages,
amounting to 850MB.
But when I yum-installed preupgrade, and then ran preupgrade,
I got the error:
-----------------------------------------------------
[tim@harriet yum.repos.d]$ sudo preupgrade
Xlib: connection to ":0.0" refused by server
Xlib: No protocol specified

Traceback (most recent call last):
  File "/usr/share/preupgrade/preupgrade-gtk.py", line 19, in <module>
    import gtk
  File "/usr/lib/python2.5/site-packages/gtk-2.0/gtk/__init__.py", line 76, in <module>
    _init()
  File "/usr/lib/python2.5/site-packages/gtk-2.0/gtk/__init__.py", line 64, in _init
    _gtk.init_check()
RuntimeError: could not open display
-----------------------------------------------------

I didn't really expect preupgrade to upgrade this machine to Fedora-10;
but why is it offered if it doesn't work?

Are you running as root?  Does root have access to your X-server to open 
windows?  (Is X11 even running?)  the "$" prompt indicates that you are 
running as a user.

What does running "pre-upgrade-cli" do when run from a root account?

I tried this earlier (before F10 was released) and all attempts failed 
due to conflicts.

Well, I did say "sudo preupgrade".
Maybe that is not enough.
And I was running X11.

Thanks for the suggestion.
I'm just running
    preupgrade-cli Rawhide
and hundreds of packages are being listed for updating -
an amazing mixture of fc7, fc10 and fc11 files.
Total download size: 1.9GB.
I can't believe this will work but I'll try it ...
there are 1661 transactions being made ...

Sorry, I read too fast and missed the sudo part.  B^{

ISTR that under some circumstances X11 doesn't like root connecting to 
your server.  Check your xhost settings.  I was *very* happy when emacs 
decided to simulate -nw when the X11 window failed to open between machines.

yeah, I had the same amount.  You will find some conflicts with RPM 
versions and the like.  I downloaded over 1340 packages for my small 
system before it died running the transaction.  It would've been better 
if those dependencies had been caught before the download.

I tried Rawhide, F-9, and F-8.  All 3 had problems.  The F-8 one 
surprised me as I would have thought that would have been the most 
tested preupgrade....

I was running preupgrade-0.9.1.fc7 from updates-testing?

I couldn't install any newer versions due to installation dependencies 
(ye olde chicken and the egg problem).

How did your attempt turn out?
