[Jean-Baptiste Lallement]

With ubuntu-image 0.12+real1 rev39 on zesty ubuntu-image fails to create a pc-amd64 image with the following error:

Please attach your amd64.model file. Thanks!

This shouldn't happen on zesty. What version of e2fsprogs do you have installed?

[Barry Warsaw (barry)]

I'm testing the ubuntu-image snap #42 for promotion and I get the same error. The version of mkfs.ext4 in the snap is:

@subdivisions[/snap/ubuntu-image/42:1014]% sbin/mkfs.ext4 -V
mke2fs 1.42.13 (17-May-2015)
 Using EXT2FS Library version 1.43.3

So it's picking up the Xenial version. I just looked at the Launchpad recipe:

https://code.launchpad.net/~canonical-foundations/+snap/ubuntu-image

and it's using the Xenial archive for the stage-packages, so that probably explains it. IIRC, Xenial is recommended by the snapcraft documentation, but let me switch that over to Zesty, rebuild and try again.

[Barry Warsaw (barry)]

Nope, Zesty as the archive for stage-packages does not work.

https://launchpadlibrarian.net/295856667/buildlog_snap_ubuntu_zesty_amd64_ubuntu-image_BUILDING.txt.gz

I do remember reading somewhere that Launchpad recipes must target Xenial, but I can't find that documentation any more (nothing comes up on help.launchpad.net or snapcraft.io). If that's the case, auto-build recipes in Launchpad should be disabled because it's worse to produce broken snaps than no snaps at all. We'll just have to do manual builds.

[Barry Warsaw (barry)]

Right, only Xenial for now.

https://bugs.launchpad.net/launchpad/+bug/1626739

In the meantime, I am going to disable the Launchpad recipe and build the snap manually.

[Barry Warsaw (barry)]

The manual, local build should work fine now.

[Łukasz Zemczak (sil2100)]

Re-opening until investigated.

[Alfonso Sanchez-Beato (alfonsosanchezbeato)]

FTR, installing a locally built ubuntu-image snap removes the issue in zesty.
