Ubuntu 2X.XX installs fail to find EFI based bootloader partition. #7224
Description
When installing on the new ubuntu 20.X and 22.X on UEFI based systems, the code for creating a default partition sets the grub_device: tag on the device, and not a partition:
- {id: disk-detected, ptable: msdos, path: $INSTALL_DISK, wipe: superblock,
preserve: false, name: '', grub_device: true, type: disk}
- {id: boot-part, device: disk-detected, size: 512MB, flag: boot,
type: partition, preserve: false}
Which makes this code fail:
https://github.com/canonical/subiquity/blob/main/subiquity/models/filesystem.py#L1565
elif self.bootloader == Bootloader.UEFI:
for esp in self._all(type='partition', grub_device=True):
if esp.fs() and esp.fs().mount():
if esp.fs().mount().path == '/boot/efi':
return False
return Truechanging the code in pre.ubuntu.subiquity to this:
- {id: disk-detected, ptable: msdos, path: $INSTALL_DISK, wipe: superblock,
preserve: false, name: '', type: disk}
- {id: boot-part, device: disk-detected, size: 512MB, flag: boot,
type: partition, preserve: false, grub_device: true}
Seems to solve the problem.
