Hi,
I have upgraded my 12.3 opensuse version to the 13.1 and yast was working at that point. I have installed prior the upgrade snorby which require ruby 1.9.x.
Now that yast works with ruby 2 pre-installed, I had to install ruby 1.9.3. I have used this method:
https://www.ruby-lang.org/fr/downloads/

I have went through the process of installing and configuring snorby again but I made it works.
But now, yast does not work anymore. The only thing I see in the /var/log/YaST2/y2log log file is:

I don't know what exactly is not working here. 
Maybe I have broke something with my ruby 1.9.3 installation...


Reproducible: Always

Steps to Reproduce:
1. Upgrade 12.3 with snorby installed and ruby 1.9.x to opensuse 13.1
2. Install ruby 1.9.3 using https://www.ruby-lang.org/fr/downloads/
3. Setup snorby then yast no longer works
Actual Results:  
Yast sinply return to the shell, no error on the console

Expected Results:  
yast should open

Comment 1 Lukas Ocilka 2013-11-22 16:07:52 UTC

Josef, please, have a look... insufficient hard-dependencies for Yast or
user error breaking their system too much?

If you don't speak French, use https://www.ruby-lang.org/en/downloads/

Romain: I suggest you to install both Ruby versions from RPM at once:

    Packages `ruby20` and `ruby19`

Search for `ruby` and you will see...

Comment 2 Lukas Ocilka 2013-11-22 16:09:07 UTC

Right now, I have these two packages installed at once:

  * ruby19-1.9.3.p448-2.1.3.x86_64
  * ruby20-2.0.0.p247-3.2.1.x86_64

Comment 3 Lukas Ocilka 2013-11-22 16:09:40 UTC

Please try as suggested above (NEEDINFO for now)

Comment 4 Josef Reidinger 2013-11-25 08:38:23 UTC

maybe related pull request that can help https://github.com/yast/yast-yast2/pull/155 . Yast need same major version of ruby as one to which it is compiled. I am not sure how manual install can break various linking to libraries.

Thanks for the information. I see in the comments on the github link that some code will be pushed into to factory but I guess it will not be updated in 13.1.

Well, with 1.9 and 2 from the official rpm packages of opensuse, things work as expect for yast. Is there a way to switch from one ruby environment from the other so snorby will compile/install with the 1.9 opensuse version?
Right now, if 1.9 and 2 (officials) are installed, snorby only detect the 2.

I will post also something on snorby forum to know what could be done.

Thanks

I recommend to ask on opensuse-ruby mailing list (http://lists.opensuse.org/opensuse-ruby/), maybe some ENV variables that set ruby paths can help. or update-alternative maybe work, it depends how ruby packages are created.

Clossing this as invalid as yast doesn't support using mix of official and unofficial ruby.

Thanks for your report
