Running cactus serve for the first time - Unable to autolaunch a dbus-daemon without a $DISPLAY for X11

[crmpicco]

I have installed Cactus for the first time and have created a Cactus project, however when I run cactus serve I get the error below.
Created the project...

cactus create ~/www.crmpicco.co.uk
New project generated at /home/vagrant/www.crmpicco.co.uk
cd ~/www.crmpicco.co.uk/

Tried running cactus serve from the project folder

[vagrant@crmpicco ~/www.crmpicco.co.uk]# cactus serve

FWIW, i'm on CentOS 7

[vagrant@crmpicco ~/www.crmpicco.co.uk]# cat /etc/redhat-release
CentOS Linux release 7.0.1406 (Core)

Looks like an issue with the underlying keyring library. I think using the workaround provided in jaraco/keyring#162 might solve your problem as well.

Basically, follow the instructions here, and set up a custom keyring path.

The keyring will be used if you attempt to deploy this site to store your provider credentials.

Let me know if this helps,

Cheers,

This might be something Cactus should perhaps account for (at least by not throwing an error if you weren't going to use the keyring anyway, which is your case). Might be a case of importing keyring inside the functions that use it. I'll have a look.
