Unable to install etherpad-lite (Ubuntu 16.04.3 LTS (GNU/Linux 4.4.0-87-generic x86_64))

[your1p]

I use Ubuntu instance created from Vagrant, and following the instructions of installing Etherpad, after executing the bin/run.sh, it will fail :
I use Etherpad version 1.6.6 since 2 month and it already works. I don't understand why it fail now.

Ensure that all dependencies are up to date...  If this is the first time you have run Etherpad please be patient.

@your1p, do you have more details about your environment (os, node & npm version, output of git log -1 and git status)?

[your1p]

Yes, of course.

git log -1 :

commit 275f1b1fef88333b0d8a0bcc1f36fe28f244add9

    Merge new release into master branch

git status :

HEAD detached at 1.6.6
Untracked files:
  (use "git add <file>..." to include in what will be committed)

	.npm/

nothing added to commit but untracked files present (use "git add" to track)

I use npm 3.8.6 anf nodejs 5.12.0 on a Ubuntu 16.04.03 LTS full stock on vagrant.

[your1p]

Fixed. In my environnement, Etherpad need Nodejs 8.x minimum to work.

[muxator]

@your1p, could you do a short debrief on this?

Version 1.7 was the first that started explicitly checking the nodejs version, requiring at least 6.9.0, and deprecating anything < 8.9.0, plan, PR).
Starting from Etherpad 1.8, thus, node 8.9 will be the minimum supported version.

I ask this because I would have expected that the documentation and the startup messages should have been clear enough, but probably they weren't.

What could have you spared you this time? Did the startup error not fire? Is the requirement in the documentation clear enough?

Thanks for your help
