For the package maintainers; Situation: We have an old freenx server farm running RHEL 6 and freenx server software. This farm consists of 9 nodes and two load balancers. We are looking to switch from RHEL to Fedora 20 and x2go was selected as the best solution to populate the new server farm. We were really impressed with the client server performance and the activity of the project. I have been following the instructions on:

http://wiki.x2go.org/doku.php/wiki:advanced:x2gobroker:loadbalancing

However, I have run into a problem with building a load balancer with the x2gobroker.

I configured the x2go repo on our servers:

# cat /etc/yum.repos.d/x2go.repo [x2go-releases] name=Upstream X2Go Packages (release builds) baseurl=http://packages.x2go.org/fedora/20/main/$basearch gpgcheck=0 enabled=1 protect=0

[x2go-heuler] name=Upstream X2Go heuler Packages baseurl=http://packages.x2go.org/fedora/20/heuler/$basearch gpgcheck=0 enabled=1 protect=0

#[x2go-nightly] #name=Upstream X2Go Packages (nightly builds) #baseurl=http://packages.x2go.org/fedora/20/main/$basearch #gpgcheck=0 #enabled=1 #protect=0

Here is what I experienced when I go to install the session broker authservice package.

Error: Package: x2gobroker-authservice-0.0.3.0-0.0x2go1.0.git20150221.892.heuler.fc20.x86_64 (x2go-heuler) Requires: python-pampy

You could try using --skip-broken to work around the problem You could try running: rpm -Va --nofiles --nodigest [root@x2go-lb1 ~]#

So I know that python-pampy was phased out by the python-pam package. However, I am running Fedora 20 and I don't seem to have the corrected rpms that the Debian distros received in the heuler repo. I learned about the Debian fix from the list serv archives:

http://lists.x2go.org/pipermail/x2go-user/2013-October/001629.html

So I created a python-pampy rpm and installed it in an attempt to fix the dependancy problem.

As you can see the x2gobroker-authservice.x86_64 package needed the python-pampy, but now it wants to install the right python-pam package which will conflict with python-pampy.

Is it possible, for convenience purposes to fix the Fedora 20 repo or is there a better way I am unaware of. Thank you for your assistance.
