[X2Go-User] x2goserver install on Centos 5

[Mike DePaulo]

Hi Michael,

x2goserver depends on multiple NX-related packages. So we need those to
install correctly before x2goserver can be installed.

If x2goserver is installed, but "x2golistsessions" cannot be found, then
that is another problem.

It looks like you are getting those signature errors because of another
limitation of EL5.
http://adminotes.blogspot.fr/2011/12/centos-6-rpm-sign-problem-v4-signatures.html

I do not see a quick fix for this.
(We cannot follow that webpage's instructions because do not have a
~/.rpmmacros file in our buildscript.git repo.)
So I submitted a bug to our bug tracker:
http://bugs.x2go.org/cgi-bin/bugreport.cgi?bug=699

In the meantime, in your x2go.repo file, you have "gpgcheck=0", right?
That will disable the GPG check. I am hoping that will work around the
issue for you and all other EL5 users.

Another possible workaround is for you to pass --tolerant to yum.
