It seems none of the APIs, neither from CLI nor in the horizon can be called.

I have error for all of them.

Hello there,

I did upgrade the packages and repo, and something were upgraded:

BEFORE:
root@gregion83:~# apt-cache policy nova-api | head -n 10
nova-api:
  Installed: 3:29.2.0-0ubuntu1.1
AFTER:

root@gregion83:~# apt-cache policy nova-api | head
nova-api:
  Installed: 3:31.0.0-0ubuntu1.2~cloud0

I also did add "DEBUG=True" under "default" section of /etc/nova/nova.conf in my region and tried to create server, but I cannot find any important logs or details to see what's wrong:

My last openstack version was 6.6.0, and I did upgrade after another email I sent "How to install Flamingo openstack in Ubuntu 24".

Before upgrade, everything was working fine, but now I have issue.

Would you please help me for this?

Regards,

Ahmad
