At the end of preupg I can see: Upload results to UI by command: e.g. preupg -u http://127.0.0.1:8099/submit/ -r /root/preupgrade-results/preupg_results-*.tar.gz . Which does not work: # preupg -u http://127.0.0.1:8099/submit/ -r /root/preupgrade-results/preupg_results-*.tar.gz . Usage: preupg [options] preupg: error: http://127.0.0.1:8099/submit/ doesn't seem to be an XML-RPC server I know that I should somehow somewhere install-configure-whatever to do to get that xml-rpc server working but if I have installed 'preupg' and it tells me to do something and it does not work - as an admin I am really confused. Would it be possible at least add some hints to the output - how to run that server or if the server is not correctly configured - don't tell me to do something which is not working. Version: preupgrade-assistant-1.0.2-33.el6.x86_64
This is great example what is more user-friendly behaviour: # redhat-upgrade-tool-cli --network 7.0 --instrepo http://download.eng.brq.redhat.com/rel-eng/latest-RHEL-7/compose/Server/x86_64/os/ --addrepo optional=http://download.eng.brq.redhat.com/rel-eng/latest-RHEL-7/compose/Server-optional/x86_64/os/ Command not found. Install package 'redhat-upgrade-tool' to provide command 'redhat-upgrade-tool-cli'?

I find it pretty obvious that if you haven't installed and set up your instance of UI, uploading results to non-existent server will fail. I guess that we could improve the message to something like: "Cannot connect to UI. Is it set up? Can this machine access it?"
Yes you find it obvious because you developed it. I dont find it obvious because I dont know that tool as well as you. That UI is part of preupgrade, preupg command tells me to do something with it and it just does not work! Some additional text with hints what is problem would be great.
I agree text should be improved - however as I see there e.g. (exempli gratia) , it is obvious to me that this is just example of the "upload command" - and not something for cut&paste.
I have fixed this in upstream. commit 97346b1f8ee802728c4a47259faad1028468415f Author: Jakub Dorňák <jdornak@redhat.com> Date: Wed Sep 3 15:50:19 2014 +0200 Usability: suggest to install UI Resolves: #1125228 preup/application.py | 9 ++++----- 1 file changed, 4 insertions(+), 5 deletions(-)
