UnicodeEncodeError: 'ascii' codec can't encode character u'\u2018' in position 56414: ordinal not in range(128)

The issue here is not the UnicodeEncodeError, when I checked the log file given by tox in the beginning(file /opt/stack/zun/.tox/venv/log/genconfig-1.log), it was due to "python.h" not found.

After I installed python3-dev packages the following file got installed with it the issue got resolved.

$ ls /usr/include/python3.6m/Python.h 

/usr/include/python3.6m/Python.h

Very few files were getting showed up earlier.

$ ls /usr/include/python3.6m

Imaging.h  ImagingUtils.h  ImDib.h  ImPlatform.h

How do I login to CoreOS installation.

After installing my CoreOS for the first time. I was startled to see login prompt. I tried various default passwords nothing worked. Thanks to following blog, here is what worked for me. https://www.netroby.com/view/3795

If you just installed CoreOS, you do not set password, Now you have a chance to set it up again.

Once you see the boot screen , press keyboard, let grub menu hang up.

and type e, to enter edit mode.

you may see console=tty0 and etc,

Just put these code insert after it

coreos.autologin=tty1 coreos.autologin=ttyS0

And press F10 to boot system, now you have the chance to set up your password.
