Augeas related error messages under Debian Jessie

[kalbfuss]

I am receiving multiple warnings and error messages which seem to be related to Augeas (see end of ticket). Since I am new to puppet and have never worked with Augeas before I am unable to solve (even understand) the problem. Here is the puppet code I am trying to execute:

.../puppet/modules/my_mail/manifests/dovecot.pp

class my_mail::dovecot {
include dovecot
class { dovecot::ssl:
ssl => 'yes',
ssl_keyfile => '/etc/ssl/private/ssl-cert-snakeoil.key',
ssl_certfile => '/etc/ssl/certs/ssl-cert-snakeoil.pem',
}
include dovecot::sieve
class { dovecot::master:
postfix => yes
}
include dovecot::mail
class { dovecot::lda:
postmaster_address => '[email protected]'
}
include dovecot::imap
include dovecot::base
include dovecot::auth
}

.../puppet/manifests/site.pp

class { 'my_mail::dovecot' : }

Some facts about my setup:

OS: Debian Jessie (Raspbian)
Puppet: 3.7.2-4
mjhas/dovecot: latest (2016-03-19)
Postfix: 2.11.3-1

Anything I can do to fix the problem? I will be happy to test and provide further information. Thanks in advance for any help you can provide.

Cheers,

Bernd

In the meanwhile I have found out that the problem was exclusively augeas related. A broken lense ("yum.aug") prevented augeas from starting properly. In the presence of this lense, the following error messages were returned by augtool:

$ augtool /print//error
error: Syntax error in lens definition
/usr/share/augeas/lenses/dist/yum.aug:33.14-.37:Undefined variable Build.combine_three_opt
/usr/share/augeas/lenses/dist/yum.aug:43.28-.35:Undefined variable entries
/usr/share/augeas/lenses/dist/yum.aug:49.34-.40:Undefined variable record
/usr/share/augeas/lenses/dist/yum.aug:58.22-.25:Undefined variable lns

Deleting the lense fixed the problem.
