Title: Message Title

Les Aker created an issue   Puppet / PUP-7782 execpipe raises method error if the command fails with no output Issue Type: Bug Affects Versions: PUP 5.0.0 Assignee: Unassigned Components: Types and Providers Created: 2017/07/15 4:22 PM Environment: Archlinux running on Raspberry Pi 3, Ruby 2.4.0 Puppet 5.0.0 Priority: Normal Reporter: Les Aker I'm trying to install a package as followed: package { 'unifi': ensure => latest } The error I get with --debug: Debug: Prefetching pacman resources for package Debug: Executing '/usr/bin/pacman -Q' Debug: Executing '/usr/bin/pacman -Sgg' Debug: Executing '/usr/bin/pacman -Q' Debug: Executing '/usr/bin/pacman -Sgg unifi' Error: /Stage[main]/Unifi/Package[unifi]: Could not evaluate: undefined method `encoding' for #<IO:(closed)> Did you mean? set_encoding Notice: /Stage[main]/Unifi/Service[unifi]: Dependency Package[unifi] has failures: true Did some digging, and the command it's failing on is where it checks for package groups: https://github.com/puppetlabs/puppet/blob/5.0.0/lib/puppet/provider/package/pacman.rb#L102 So it calls execpipe with the command, and the command returns 1 because the group doesn't exist, but otherwise returns no output. This lands us here: https://github.com/puppetlabs/puppet/blob/5.0.0/lib/puppet/util/execution.rb#L86 The act of returning "output" as part of the exception attempts to stringify it. It's a closed IO pipe, so that fails when trying to call ".encoding". I confirmed this by replacing "output" on the raise line with an empty string, which fixed the error.
