As known issues are discovered in Puppet 5.5 and its patch releases, they’ll be added here. Once a known issue is resolved, it is listed as a resolved issue in the release notes for that release, and removed from this list.
Testing modules using rspec-puppet versions earlier than 2.7.10 results in the error “undefined local variable or method
default_env for Puppet::Util:Module”. As a workaround, update rspec-puppet to version 2.7.10. If using PDK, run
pdk bundle update rspec-puppet or update your PDK package. If not using PDK, run
bundle update. PUP-10586
host type supports only one IP address for each hostname. Because of this, you cannot use both an IPv4 and IPv6 address for the same hostname. PUP-9480
Puppet 5.5.11 adds support for macOS 10.14 Mojave. However to manage users and groups, you must grant Puppet Full Disk Access. To give Puppet access on a machine running macOS 10.14, go to
System Preferences > Security & Privacy > Privacy > Full Disk Access, and add the path to the Puppet executable. PA-2226, PA-2227
Puppet runs generate an autosign warning, indicating that autosign is deprecated. We’re un-deprecating autosign in a future release and you can ignore this warning.
PUP-8009: Puppet 5.1.0 introduced support for internationalized strings in Puppet modules. However, this feature can cause significant performance regressions if environment caching is disabled, for instance by setting
environment_timeout==0, even if the module doesn’t include internationalized content. Puppet 5.3.2 introduced an optional
disable_i18n setting in
puppet.conf to avoid using localized strings and restore degraded performance.
When specifying a deep merge behaviour in Hiera, the
knockout_prefix identifier is effective only against values in an adjacent array, and not in hierarchies more than three levels deep. HI-223
Puppet 5 stdlib functions handle
undef less strictly then they should. In Puppet 6, many functions from stdlib were moved into Forge modules, and now treat
undef more strictly. In Puppet 6, some code that relies on
undef values being implicitly treated as other types will return an evaluation error. For more information on which functions were moved out of stdlib, see the Puppet 6.0 release notes.
