Bug Description

I am trying to install salt to a handful of remote machines in the wild running Ubuntu 10.04 LTS. With that said, previous to the installation of Salt, Xibo runs perfectly. Once salt is installed, it doesn't play nicely. Xibo starts, but it no longer phones home to the server. Pressing the i key while xibo is running brings up the information screen but shows no connection information and amber lights for required files and schedule. Salt installs a new python2-mcrypto which appears to be causing the problems.

Trying to exit xibo, pressing the q button, locks up xibo and must be killed with signal 9.

With all of the above said, this is all being done to upgrade a good amount of xibos to 1.4. I've succeded in upgrading my OS from 9.04 to Ubuntu 10.04. Before I upgrade the server to 1.4, I'm getting my machines up to date so they can update at the same time or as close as possible. The only thing holding me back is integrating Salt with the clients running xibo.

Here is the output of run.sh:

Have you got the Ubuntu ca-certificates package installed too?

Sure do. For clarity, the xibo server is running with a signed cert.

In general we prefer you ask your question in Launchpad Answers. If after we've looked into a question a bug is found we can convert it over.

In this case I suspect if there is an issue it will be in the soappy package not in Xibo.

Try installing ca-certificates package and I suspect that will get rid of the error.

It's already installed. I forced a reinstal and ran xibo again. It failed with the same error message.

Looks like a bug in the M2Crypto module which when installed overrides the default python urllib implementation:

https://bugzilla.osafoundation.org/show_bug.cgi?id=2341

Try commenting out line 2605 in XiboClient.py so it reads:

        try:
            # socket.setdefaulttimeout(self.socketTimeout)
            log.log(2,"info",_("Set socket timeout to: ") + str(self.socketTimeout))
        except:
            log.log(0,"warning",_("Unable to set socket timeout. Using system default"))

I'll target this so we catch the possible exception being thrown, and see if we can find a better way to work around this.

1.4.3 should now catch this exception and also in it's default configuration will no longer set a socket timeout unless one has been specifically set in the site.cfg file.
