malformed format string - %{ at install3.pp:122

[amateo]

I'm trying to use tp to install and configure exim in ubuntu 14.04 servers. I'm running puppet 3.8.6 and my puppetservers is an ubuntu 12.04. My puppet code is

tp::install3 {'exim':}

In the reported line, the line is:

$tp_settings=tp_lookup($title,'settings',$data_module,'merge')

Debuging the tp_lookup function I've found that the problem is trying to load the hiera.yaml file at modules/tinydata/data/exim/hiera.yaml. The content of this file is:

---
 :hierarchy:
   - "%{title}/osfamily/%{osfamily}"
   - "%{title}/default"
   - default

and the %{ shown in the error is the one for %{title}. If I remove all %{xxx} in this file then puppet works (although I'm not sure it is using the correct information for the exim configuration)

Any help? Thank you.

Probably you have an unsupported version of ruby on the puppetmaster. Check these: https://github.com/example42/puppet-tp#prerequisites-and-limitations

You right. I'm running ruby 1.8.7 in my puppemaster:

# facter -p rubyversion
1.8.7

If you want to experiment with tp, I suggest to do it in a Puppet 4 installation. Puppet 3 tp defines are actually more used and tested, but are less likely going to benefit of future enhancements.

I know it. My problem is that I'm now migrating from puppet 3 to puppet 4 and I need to maintain some compatibility. In fact, I'm using tp to replace some modules that are not puppet4 compatible (f.e. example42/exim that I was using now). But I could handle this in other way.
