tacker install failure (stable/rocky)

[Gurol Akman]

Hello,

While I successfully installed tacker (stable/queens; devstack; all-in-one) on an Ubuntu 16.04 server, I failed to install tacker (stable/rocky; devstack; all-in-one) on the same type of server. Here's the relevant portion of the ./stack.sh output. Any suggestions about what may be wrong?

Thanks in advance,

Gurol

I suggest that local.conf file like this one https://github.com/openstack/tacker/blob/master/devstack/local.conf.example. You can update to stable/rocky and before run stack.sh, please completely uninstall devstack as this guide: https://nguyentrihai.com/?p=481

I hope that can help you.

Thanks a lot, Cong Phuoc. It's of great help. While I continue to have issues w/ devstack rocky installation due to glance uwsgi related changes, I can now do clean/repeat runs, thanks to the cleanup procedure provided. Best regards!
