I am trying to run a Ubuntu Core image inside of a qube. However on start I see similar symptoms as described in this post: kvm - `error: invalid signature.` when trying to boot Ubuntu Core - Ask Ubuntu which are
- the error message
error: no such device: ubuntu-bootafter
Booting from Hard Disk ...,
- then the message
error: invalid signature,
- then the grub menu showing the following three different entries
Recover using 20210118, leading to
error: invalid signaturewhen followed,
Install using 20210118, also leading to
error: invalid signaturewhen follwed and
UEFI firmware settings, leading to
error: can't find command 'fwsetup'when followed.
If I understand problem and solution correctly, UEFI boot needs to be enabled for the qube. Is it possible to tell a qube to perform a UEFI boot?
(I didn’t find anything the like in the
qvm-run man pages, the Qubes OS documentation, nor anywhere else on the internet.)
If I misunderstood problem and solution, feel free to edit.
