Fresh 5.0.7 install fails to work on OSX

Development Installer
1

The last week I've been installing Plone 5.0.6 and 5.0.7 on my OSX system with the unified installer without problems.
I use homebrew to install python.
Everything went fine until yesterday when a fresh install fails with the following error:

$ bin/plonectl fg

I have reinstalled python, redownloaded the Plone installer. All to no avail. Even tried on another OSX system: same error.
Any ideas? TIA

Hi Marcel,

I can't help, but co-incidentally I have been trying to install 5.0.7 on an Ubuntu Trusty (14.04) server today, with exactly the same results, so whatever the issue is I don't think that its particular to OSX. The same server has 5.0.6 instances installed from that version's binary installer, FWIW.

I've run out of time just now, but if I find a solution I will report it here.

Cheers,

PhilK

@mjmare @glimmung I can confirm I received the same error trying to install Plone 5.0.7 on my other Ubuntu 16.0.4.2 droplet on DigitalOcean during the weekend (already installed it successfully on one droplet).

I've installed Plone successfully on my macOS Sierra (10.12.3) as well, but I just created another account after seeing this thread and encountered the same error as you after installing it.

I'm glad to know I'm not the only one encountering this. I'll try to troubleshoot and see if I can find out what's causing this, but if anyone finds a solution, definitely report back!

I also got the same error. Both on CENTOS 7 and Ubuntu 16.0.4.2 droplets at DigitalOcean.

This the error from CENTOS7.

I've gone ahead and submitted this as an issue in the Unified Installer repository at https://github.com/plone/Installers-UnifiedInstaller/issues/59

Very strange, I was able to successfully install Plone 5.0.7 on Ubuntu 14.0.4 but it definitely failed on Ubuntu 16.04.2 (this is on Hetzner).

it's setuptools fault; for a workaround see:

@hvelarde Thanks for posting the workaround! I'm on mobile, but I'll try it out later. :slight_smile:

Successfully installed on centos 7 and Ubuntu 16.04.2. I updated my setuptools. I followed https://packaging.python.org/installing/
. Thanks a lot.

Works again. Thx!
