What happens if you remove the USB drive and attempt booting? Post-install we might be having issues with conflicting partition labels from the USB and NVME drives. We’ve got a udev rule that prioritizes USB over a local drive, which might explain why setting up the /usr-verity image is failing.
You could also try wiping the NVME drive (sgdisk -Z /dev/nvme0n1) and re-attempting the install process. If you get that original error during install it will probably be the root cause of why the system won’t boot post-install.
There’s no boot menu option for the internal install; only the USB. I will probably have to wipe the internal drive in order to reinitiate the install process because I’m unable to get it to work at the moment.
In the lsblk output it looks a bit suspicious that a partition from the NVME drive is mounted at /boot when I selected to boot from the USB. Surely /boot should be mounted from the USB drive? I think whatever went wrong during the initial install is now preventing the installer from running again.
I’ll try to wipe the drive. Can I do that in emergency mode?
Alright, I wiped the internal drive using another bootable USB. Ran the installer again and this time it worked which I’m happy about - and unsatisfied that we won’t be able to figure out what went wrong the first time. I had Proxmox installed on the drive previously so maybe that caused it.
Thank you both for the help. Looking forward to properly trying out IncusOS.
