librarian-puppet fails on ec2 cloud-init, where HOME is not set.

[seanmcl]

cloud-init on ec2 instances doesn't set the HOME env variable. As a result, librarian-puppet dies.

librarian looks for things in the home folder, so you just need to set HOME (to whatever dir you want) before calling librarian-puppet

[gene1wood]

Here's the workaround I'm using based on @carlossg's comment

cd /path/to/Puppetfile/and/modules && HOME=/root librarian-puppet install
