  Thread Previous • Date Previous • • Thread Next 
Public bug reported:

"openstack server list" throws  HttpException: 500: Server Error for url:  Unexpected API Error.
Other commands (like image, volume, network list commmands are fine)
I can also do "openstack server show"
I am running Dalmatian release in ubuntu 24.04

# openstack server list
