Puppet users - Jan 2012 - augeas error: Could not evaluate: unknown error - Failed to initialize Augeas

Hi,

I am running puppet 2.6.12 on a SLES11SP1 server. I get the following error
message as part of the puppet catalog run on a SLED11SP1 client.

Augeas[sap_host_entries](provider=augeas): Opening augeas with root /, lens
path , flags 0
err: /Stage[main]/Sap/Augeas[sap_host_entries]: Could not evaluate: unknown
error - Failed to initialize Augeas


Can somebody shed some light on the error message above

The test module (code listing below) i have created attempts to add a
comment line to the /etc/hosts file on the client machine. I have tested
the module on the server with augtool and it works correctly.

class sap {
          augeas { "sap_host_entries":
                 context => "/files/etc/hosts",
                 changes => [
                        "set #comment[last()+1]
''Sap-specific-hosts''",
                        ],
          }
}

On the client I have the following augeas and ruby vendor based packages
installed

augeas-devel-0.8.1-7.8.2
libaugeas0-0.8.1-7.8.2


ruby-devel-1.8.7.p72-5.30.5
rubygem-rake-0.8.7-0.1.4
ruby-1.8.7.p72-5.30.5
rubygems-1.3.7-1.3.3


On the server i have the following augeas and ruby vendor based packages
installed

augeas-0.8.1-7.8.2
augeas-lenses-0.8.1-7.8.2
libaugeas0-0.8.1-7.8.2

Cheers
Lawrie

Thanks for the reply.

I have now installed  the augeas ruby bindings on the client by
getting

wget http://augeas.net/download/ruby/ruby-augeas-0.4.1.gem
and running

gem install ruby-augeas-0.4.1

Building native extensions.  This could take a while...
Successfully installed ruby-augeas-0.4.1
1 gem installed
Installing ri documentation for ruby-augeas-0.4.1...
Installing RDoc documentation for ruby-augeas-0.4.1...

Alas, i am still getting the same error message.

Is there any extras i need on the server or client?

Thanks

The rpm-based installs of the other components probably expect different
paths than the gem is providing. IMHO you shouldn''t mix rpm and
gem-based
installs. Weirdness is virtually guaranteed. Pick one style or the other
and stick with it.

Thanks for the tip Aaron.

I have stuck with the platform RPMs as indicated earlier in the
thread. I could not find a ruby-augeas SLED platform RPM.

I downloaded the ruby-augeas-0.4.1-1.el5.src.rpm and tried to rebuild
it on the SLED11SP1 machine.

I had to make changes to the spec file to get rpmbuild to run.

Changed a line in the ruby-augeas.spec file
from
BuildRequires:  ruby ruby-devel rubygem(rake)
to
BuildRequires:  ruby ruby-devel rubygem-rake

Now it attempts to build a new RPM for the SLED11SP1 platform but
fails at the rake testing phase with 13 errors, output follows

+ rake

augeas-0.4.1)

I have left out Errors 2....12 for clarity.

Hope you can help as I really need to get this working.

I''m not familiar with the SUSE community, but I do see a number of
ruby-augeas RPMs and SRPMs on the build service.  Picking one at random:

https://build.opensuse.org/package/show?package=ruby-augeas&project=home%3Ajustin_kinney

The spec doesn''t seem to have a %check section though, so you might
find
it just masks the problem below until later.

That looks pretty bad!  Does Augeas function properly on your system to
begin with?  I''d suggest running "augtool" and seeing if you
get the
same error.

(From the quote below, you may need to install another package for the
Augeas command line tool).

If you get the error, try creating an empty directory and run "augtool
-r /path/to/dir" to rule out problems with files on your system.

This is interesting, does the libaugeas0 package contain any lens files?
 I can''t find a spec for it to see how the SUSE package is split up,
but
the EL/Fedora package would put them in the augeas-libs package:

$ rpm -ql augeas-libs | grep -c \.aug\$
219

The lenses should generally match the Augeas library version so check
they''re in sync if supplied by another package.
