Dears,
if your VPS supplier is using OpenVZ as mine and you are not successful in installing Erpnext via Easy Install, do not bother pushing this forum.
I realized to my recent experience that most of the time Easy Install breaks is when systemd functions like localectl do not work on the VC templates. Going through the setup scripts and omitting some roles which happen to be really unnecessary does the job up to some extend but do follow a manual install and be careful when you install bench and erpnext if it is a production or development environment.
Just sayin’…
