Ubuntu instance not reachable after installing updates

Hello,

Yesterday I installed updates on my server and after rebooting I could not log in anymore. After restarting it, I could ping it shortly and after some seconds the ping does not reply anymore.

Could it be that there is some malfunction within the Linux kernel (I received message to reboot as new kernel was installed).

Below more information about my server:

    I'm having the same problem. When it will be fixed. I haven't installed any update, I just got system reboot required (oracle probably updated ubuntu kernel), so I rebooted and I can't connect to the instance (serial console is not working too).

    Thanks for your reply. As a test I restored a volume backup of march, created new vm instance with this and installed all updates. After reboot I hadd thevsame issue. As I understand from your message only a reboot can trigger the problem.


    I have now restored my vm with the backup and won't reboot it as long as this issue persists.
