[Bug 1861655] Re: [Ubu 20.04][kernel-5.4.0-12-generic][WSP-DD2.3] Unable to install Ubu 20.4 on NVMe disk

[Frank Heimes]

Thx Michael for giving it a try.
So that is an issue that we recently also ran into.
Means the issue described by you in comment #27 is addressed in this Bug:
https://bugs.launchpad.net/ubuntu-power-systems/+bug/1867780
And it is currently looked at ...

Once this is done we can double check the grub install later in the
sequence (hence I'm not marking that as duplicate for now ...).
