stack.sh stable/havana fails on Ubuntu 12.04.2

[Joel Wright]

stack.sh fails to complete using the stable/havana branch on Ubuntu 12.04.2. The log shows lots of errors regarding the six dependency:

Traceback (most recent call last):
 File "/usr/local/bin/swift-init", line 4, in <module>
   from pkg_resources import require; require('swift==1.10.0.7.gf9c44df')

The script ultimately fails attempting to create glance images:

commit e4dda729ef9670927978f49c9d21f160c0457efb works fine, so this seems to have been caused by one of the following:

"be opinionated: only use get-pip.py" (commit 6bb36694994ce051798f8a0e975de1b82e62f831)
"make get-pip.py download failures more clear" (commit 4c8b249d01632e8090abe758dbb681a0ee68a8b9)

Try to upgrade setuptools to the newest version. It worked for me.

[Joel Wright (joel-wright-k)]

If that works it would still need to be included in the devstack stack.sh script. I'll try it, but I would expect stack.sh to "just work" on a clean install of a supported system.

[Joel Wright (joel-wright-k)]

I forgot to mention, I received the same failure on 2 clean virtual machines running a fully updated version of Ubuntu Server 12.04.2.

Will try again after also running pip install --upgrade setuptools for the system.

[Joel Wright (joel-wright-k)]

Ok, I can confirm that running 'pip install --upgrade setuptools' as root before running stack.sh on a clean install of Ubuntu Server 12.04.2 allows the script to complete successfully, but leaving that step out causes the script to fail.

Upgrade setuptools doesn't seem to resolve the problem in me environment. I got the following error. Even I manually install pip 1.4.1, it is uninstalled by devstack and 1.5.6 is put on.

This issue presented itself between multiple installs, with the initial installs working fine and then all of a sudden the stack.sh failing at the downloading images section with the "400 Bad Request / Client disconnected before sending all data to backend" message. Ran "wget https://bootstrap.pypa.io/ez_setup.py -O - | sudo python" after a ./clean.sh and the stack.sh completed successsfully with the images display with nova image -list.

(As a root) Pip install and upgrade of setuptools helped me fix this issue.
