[vchepkov]

Affected Puppet, Ruby, OS and module versions/distributions

• Puppet: 6.26.0
• Ruby: ruby 2.5.9p229
• Distribution: Rocky
• Module version: 9.0.1

How to reproduce (e.g Puppet code you use)

Error occurs when provider is instantiated

What are you seeing

Mar 23 19:40:11 web201 puppet-agent[1488784]: Could not prefetch package provider 'npm': invalid byte sequence in US-ASCII
Mar 23 19:40:11 web201 puppet-agent[1488784]: Failed to apply catalog: invalid byte sequence in US-ASCII

Any additional information you'd like to impart

provider works with no issues with puppet agent -t command from a command line session,
I presume while running as a daemon some environment variable, which provider uses, is missing

It seems provider requires LANG variable to be set

# env -i puppet agent -t
Info: Applying configuration version 'c78cfbcf'
Error: Could not prefetch package provider 'npm': invalid byte sequence in US-ASCII
Error: Failed to apply catalog: invalid byte sequence in US-ASCII

# env -i LANG=en_US.UTF-8 puppet agent -t
