How to completely uninstall devstack and reinstall it?

Question

I am trying to install devstack from the following link:

https://wiki.opendaylight.org/view/OVSDB:OVSDB_OpenStack_Guide

However, ./stack.sh always throws some error. Is there any way I can remove all the configurations of devstack and redo it?

This is the error I am getting:

Command "python setup.py egg_info" failed with error code 1 in /opt/stack/keystone
You are using pip version 7.1.2, however version 8.0.2 is available.
You should consider upgrading via the 'pip install --upgrade pip' command.

run 'yum upgrade' and then try again. That should resolve the pip issue. — kpie, Jan 28 '16 at 19:00

I think the unstack.sh script is meant for that. So you just need to be in the devstack folder and fire the ./unstack.sh and sit back. Once finished you can try to reinstall with ``./stack.sh```

I am assuming you are using the devstack repo found on github https://git.openstack.org/openstack-dev/devstack.git

I was totally wrong, the unstack.sh script is not used to uninstalled but to unstack before you reboot for example. On the other end, ```clean.sh``` seems to uninstall everything including deps. – sebastienvg Aug 30 '16 at 15:53

Go through the same docs, anywhere that it says yum install use yum remove. After that check if ~/DevStack still exists. If it is there run rm -fr ~/DevStack

(You could probably leave java and @standard on your system)

Though I'm left thinking if this tutorial starts with Boot from the Fedora Net Install .iso - Select the minimal package - Select your hard disk layout you might just want to start over...

I don't think OpenFlow installs it looks like it just compiles so you might want to delete the zip and the extracted folder and re-download...

What error are you getting from stack.sh?

Literally just a dash? That's some brutality. – kpie Jan 28 '16 at 18:47
If you haven't done anything else on that installation instance just start from scratch... – kpie Jan 28 '16 at 18:48
There was a typo in my reply. Kindly look at the edited text in my question. – Aditya Gnaneshwar Jan 28 '16 at 18:49

if anyone has the same problem. The solution is to go to :

~/devstack/tools/cap-pip.txt

And set the value pip to the last version of pip, like this :

pip==18

Delete all existing folders and use this document to install it again. Remember to clone it to a new place this time. Don't override it. And if error persists do email me or comment below. I was stuck with the same problem had to reinstall ubuntu for it but then i figured this solution. DevStack Installation All-In-One Single Machine

There is no perfect solution to uninstall Devstack. Reinstalling Ubuntu is the only way through.

This is not true. You not being able to do it is not the same as it being impossible. – takendarkk Feb 15 '16 at 18:38
