Comment 3 for bug 2017297

I've tried refreshing this kernel on this same system after installing the core 16-2.59.4 from beta but I'm still not successful. I don't get the same error, but it still fails. After the system reboots, I'm unable to connect for about 15 minutes, then when I can finally connect, it looks like it's rolled back to the previous kernel:
2023-05-24T19:15:29Z ERROR cannot finish cascade-kernel installation, there was a rollback across reboot

I don't see any other indications about what went wrong, except that it looks like the first step that had an error was connecting plugs and slots:
