Hi Lalitha, About uninstall: please accept some suggestions: 1) Do exactly the backward path of the installation respecting the sequence, meaning: If you installed: Packet one Packet two Packet three You have to: Uninstall packet three Uninstall packet two Uninstall packet one 2) always use the --purge option: apt-get remove --purge my-packet x)optional:I also take a look at undeleted directories in /etc/ /var/log /var/lib, if necessary I delete them manually :-) 3) after EACH bunch on uninstall (like apt-get remove --purge nova-something-packets) always use: apt-get --purge autoremove Then, Starting from mseknibilel work I wrote a VERY similar guide for Havana and carefully tested it: https://github.com/fornyx/OpenStack-Havana-Install-Guide/blob/master/OpenStack-Havana-Install-Guide.rst Please note that openstack dev is not in my opinion the good list, perhaps openstack or openstack-doc would be better :-) BR Marco -----Original Message----- From: Lalitha Maruthachalam [mailto:lalitha.maruthachalam at aricent.com] Sent: den 20 januari 2014 10:53 To: OpenStack Development Mailing List (not for usage questions) Subject: [openstack-dev] Uninstalling openstack Hi, I had installed Grizzly release of openstack on my machine using the following link. https://github.com/mseknibilel/OpenStack-Grizzly-Install-Guide/blob/OVS_SingleNode/OpenStack_Grizzly_Install_Guide.rst I no longer need the grizzly release.
