Struggling to install Plone on Ubuntu droplet

1

I created a Ubuntu 16.04 x64 Droplet on Digitalocean and have been following this tutorial to install Plone. Everything seemingly looks like it's going well, but the install fails a few minutes after I run

./install.sh

I followed the instructions but don't know why I'm seeing this error. Any idea why?

Here's as much info as I know to provide:

root@plone:~# tar -xf Plone-5.0.4-UnifiedInstaller.tgz
root@plone:~# cd Plone-5.0.4-UnifiedInstaller
root@plone:~/Plone-5.0.4-UnifiedInstaller# ./install.sh
Testing /usr/bin/python2.7 for Zope/Plone requirements....

What is the size of your droplet? Sometimes lxml installation fails because of too little memory.

maybe I'm wrong but that message seems to point to missing OS dependencies; install them and try again:

http://docs.plone.org/manage/installing/installation.html

also, don't forget upgrade your OS before the installation and make sure you're running Ubuntu 16.04.1 at least.

no way; smallest droplet is 512MB of memory and that's more than enough; we have many droplets this size.

You are absolutely right: usually a 512MB machine is fine. But maybe there are some other services already running taking some memory. And maybe there is no swap on this machine. I had this same error for a customer once, also on a DO droplet.

No swap is definitely a likely candidate - this has caught me out repeatedly on DO droplets, as many things misbehave with none. There is a DO knowledgeable article about how to create a swapfile on an existing droplet, so easy to test/fix.

could be, but that's not what the buildout log error reads.

FTR, the tutorial is How To Add Swap on Ubuntu 12.04, and you can read there:

using swap with SSDs can cause issues with hardware degradation over time. Due to this consideration, we do not recommend enabling swap on DigitalOcean or any other provider that utilizes SSD storage. Doing so can impact the reliability of the underlying hardware for you and your neighbors.

based on my latest tests using 512MB droplets, I recommend the following settings:

[instance]
zodb-cache-size = 15000
zserver-threads = 2

[supervisor]
eventlisteners =
    memmon TICK_60 ${buildout:bin-directory}/memmon [-g app=300MB]

Thanks to all that offered help. I added a 2GB swap file to my Droplet (512MB ram) and managed to complete that step without errors and reach the setup page.

awesome! BTW, we have enabled swap in all droplets (just-in-case™) but we try not to use it at all.

Next time, you can just temporary increase your droplet size for the installation. Digitalocean allows to downsize again.
