keystone error apt-get upgrade packages version

[admgsic]

Good Morning,

I wanted to comment on a problem that has happened to me several times ...

I had the OpenStack version "Newton" recently and I updated the OpenStack version "Pike", and all right until the keystone in the controller node did not work well for me as it told me in horizon:

"An error occurred authenticating. Please try again later."

In cli command line: Failed to discover available identity versions when contacting http: // controller: 35357 / v3. Attempting to parse version from URL.
Internal Server Error (HTTP 500)

In the end I had to do a clean installation of the controller node.

But just a week ago I decided to update the packages because there were updates and bug fixes in some of them and the same error was shown again.

Horizon:

"An error occurred authenticating. Please try again later."

In cli command line:

Failed to discover available identity versions when contacting http: // controller: 35357 / v3. Attempting to parse version from URL.
Internal Server Error (HTTP 500)

Does anyone know why something like this happens every time an apt-get upgrade is done?

Greetings and thanks in advance,

hey , you can try again the same after disable or unset the proxy if you are using in case .

As far as I know, keystone doesn't emit an error message like that, but Horizon might be. Are you able to share some information from you keystone log?

Sorry, in the end I reinstalled OpenStack since I did not find out the cause of the problem ...

Thanks for the answers,

In that case I'm going to close this as invalid. Feel free to reopen if you see the issue again and can show us the keystone logs.

The error "failed to discover available identity versions" comes from keystoneauth and usually happens when it can't reach keystone, in this case it looks like keystone crashed for some reason. But the only way to know why is to see the logs.
