Xen Orchestra on Ubuntu 15.10 - Complete installation instructions

scottalanmiller

Remember when I asked what node version you were installing? That looks like Node 5. I thought XO could only work with Node 4.

What Node.js version do you have installed?

There was the question ^^^^

I never saw a response. We could have tracked this down sooner You can't just use the Node that comes with the distro. Use NVM and control the Node version.

@scottalanmiller Because it's the lastest LTS release. Isn't using LTS best practice?

No, it's a bad practice. Using something with "long term support" is a good practice, but with Ubuntu it is just a naming thing for marketing purposes. Even Canonical themselves do not recognize it as an LTS. It's just letters that they slap on every fourth release to make it sound like an enterprise product like RHEL. It isn't. Ubuntu is a rolling release will full support only for the latest build. So sticking to LTS is just "not updating" in this case. One of the many reasons that Ubuntu isn't that good. It's not "bad", but it isn't up to par.

Ubuntu is like Fedora, you always want to be on the latest unless there is a compatibility issue. You would never intentionally use an LTS release unless you are doing something like MongoDB which only releases for certain versions. And the answer there is not to use Ubuntu but to use CentOS which is kept up to date.

If you want a true LTS, Ubuntu is not an option for you. RHEL and SLES are the only enterprise long term support options in the Linux world.

@scottalanmiller Why aren't ubuntu LTS releases trully considered as having long term support? I usually use Centos but I do have several Ubuntu LTS boxes and from their documentation they appear as having long term support.

Because Long Term Support suggests that when things break, they fix them and provide support. But Canonical doesn't do that. If things really break they tell their LTS clients to upgrade to the latest non-LTS release to continue getting support. True LTS support never requires "going to the non-LTS release" to continue getting support. The label LTS and their "support marketing timelines" are just made up marketing.

Thats where terms like "marketing" and "lying" come into it.

I know shops that in 2011 were already being told by Canonical that to get support they had to leave 10.04 LTS because they would only try to fix things in the 11.04 or 11.10 releases. 10.04 has major stability bugs that were just ignored because the 11 series fixed them. The LTS theory is that fixes would be backported. But they are not. Canonical just uses LTS to fool customers, they do not mean it to mean that they will support the product.

Exactly. I was just about to look for this.

@scottalanmiller Do I have to remove the old version first?

Doh! NPM is out of date too. How do I update it?

No but better if you do. It will keep being the default.

I think NVM will handle that too.

Updated NPM using:

 curl -L https://npmjs.com/install.sh | sh

Did you do a fresh install using Node 4?

Alex Sage

@scottalanmiller No, I can try that.
