After a power off I can’t start my droplet. I didn’t do anything with the kernel but something went wrong.I am writing here because I have to wait long hours for support and so far they have not been able to help. Maybe someone has an idea.

I get this error:

At the suggestion of support, I went through these steps:

But there I ran into an other error:

Would anyone have any suggestions on how I can get my data back the fastest? I would also like to keep the IP address if possible.

Hey @jankec90,

I fear that you’ll need to have this checked by support as there is nothing to be done from this side.

Nevertheless, I have asked our amazing support team to check-in on your ticket. They will be able to help you further where we cannot! :)

Hope that helps!

Hey @KFSys,
Thank you for your reply!
The problem is still exists and the latest kernel does not work, but an older one was able to boot the droplet. Unfortunately, I haven’t been able to fix the bad kernel yet, but at least until then, my services will be available. Currently, I think only a new server will solve this issue.

Hi @jankec90,

If you are able to boot the droplet with an older kernel, that’s great, at least you can back up your data!

As for creating a new droplet, that’s always an option but one I would like to keep as a last resort. Did anyone from DigitalOcean support contact you about the issues with the newest kernel?


Hello, I have the same issue - kernel panic - unable to mount root fs.

What should I do to recover data from droplet volume?

Is it possible to create another droplet in same region and mount volume from broken droplet to a new one?

Anticipating your kind reply.

Best regards,


I am having this problem as well after attempting to upgrade Ubuntu.

Any advice or can someone from DO check the status of my ticket?

Thank you!
