Install fails on ppc64el (unrecognized partition table: 'mac')

[Paride Legovini]

Eoan live-server is currently failing to install on ppc64el. This seems to be because the partition table type of the installer ISO is detected as 'mac', which is unknown to curtin, and the validation fails:

curtin:1157 Validation error: 'mac' is not one of ['dos', 'gpt', 'msdos'] in
{
 "id": "disk-vdc",
 "path": "/dev/vdc",
 "ptable": "mac",
 "type": "disk"
}

The ppc64el Eoan installer worked up to the daily ISO with serial 20190702 (inclusive).

I'm not sure this is actually a problem in subiquity: the actual part to fix could be very well curtin or probert, but I'm filing this here for the moment. Will attach the relevant log files in the next comment.

This needs fixing in curtin.

[Paride Legovini (paride)]

The reason for which I was uncertain about curtin is that sfdisk (the tool called by probert) says that the ISO has a 'dos' partition table:

But the fix seems totally fine.

This bug is fixed with commit 86ede8a3 to curtin on branch master.

I repacked the ISO with an experimental subiquity which includes curtin from master and I can confirm the fix works.

Thanks xnox for providing the experimental subiquity snap.
