Hi there,
Log:

end

bundle exec itamae ssh  --host pg.myapp.info --user root -i ~/.ssh/id_ed25519 cookbooks/app/app_user.rb  -y nodes/pg.yml

Might be similar to this issue.

I worked around it like this:

remote_file "/home/app_user/.ssh/authorized_keys" do
  action :create
end
  
file "/home/app_user/.ssh/authorized_keys" do
  owner 'app_user'
end
