package supervisor 3.0a8-1.1 failed to install/upgrade: subprocess installed post-installation script returned error exit status 2

[Mike Metcalfe]

The first installation guide I read suggested I install the python package (pip install supervisor) which I did but had some problem (sorry, can't remember what). I'm not if it's related but now I get this when apt-get install supervisor

Setting up supervisor (3.0a8-1.1) ...
Starting supervisor: Error: No config file found at default paths (supervisord.conf, etc/supervisord.conf, /etc/supervisor/supervisord.conf, /etc/supervisord.conf); use the -c option to specify a config file at a different path
For help, use /usr/bin/supervisord -h

Hello,
this is not a bug.

Mixing the distro's package management with others will sometimes cause troubles.
Please make sure all the stuff you installed through pip is removed.
According to your error message,
it looks like supervisor cann't find your configuation file.
In debian and other debian-based distro's , the default configuation file should be at /etc/supervisor/supervisord.conf
Please try the following command:
$ stat /etc/supervisor
$ stat /etc/supervisor/supervisord.conf
Make sure that /etc/supervisor is a directory, and /etc /supervisor/supervisord.conf is a regular file (or link to a regular file)

If you found /etc/supervisor is a regular file, it will cause failure to create /etc/supervisor/supervisord.conf, you need to remove that and reinstall through apt-get, aptitude or dpkg.

Thanks for checking this out, fqj1994. I uninstalled with pip and purged with apt and it worked.
