I also get the attached screenshot when attempting to boot into recovery mode.

Would it be possible for you to test the latest upstream kernel? Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Please test the latest v4.15 kernel[0].

If this bug is fixed in the mainline kernel, please add the following tag 'kernel-fixed-upstream'.

If the mainline kernel does not fix this bug, please add the tag: 'kernel-bug-exists-upstream'.

Once testing of the upstream kernel is complete, please mark this bug as "Confirmed".

Thanks in advance.

I tried installing and testing the mainline kernel, but I encountered issues with the linux-image not generating. I also tried to install openssh-server and ssh while on 4.10.0-19-generic and I get errors that dpkg failed processing 4.13.0-25 with the new modules. I have tried uninstalling this same kernel and I encounter similar errors by dpkg.

[Scott Cohen (yetoo)]

I needed to reinstall Ubuntu and the problems I attached earlier no longer apply.

Do you see the same issue if you boot Bionic live CD/USB in VBox?
