I have uploaded the cherry-pick of snapd (https://github.com/snapcore/snapd/pull/7038) to xenial. I would still like to get the livecd-rootfs change released along with snapd as the snapd dependency *should* be arch-specific anyway. There is no user- impact in getting livecd-rootfs released along with snapd (it's a package only used during builds).
** Description changed: [Impact] - Currenty powerpc image builds are failing on xenial. livecd-rootfs is - used to build our Ubuntu images and it depends on ubuntu-image. With - ubuntu-image 1.7 the snapd dependency was bumped to >= 2.38; which is - not satisfiable on powerpc because snapd is not buildable on powerpc - with gccgo (vs golang). + Currenty powerpc image builds are failing on xenial. The main reason is + that snapd now provides a powerpc 'empty' dummy package (as the + architecture is not supported) but still ships regular maintainer + scripts that try to do operations on installed files (which are not + present due to the empty package). This basically makes the dummy snapd + powerpc package uninstallable. And since launchpad-buildd pulls in snapd + by default, this breaks any powerpc image builds currently. Also, besides that, it seems that livecd-rootfs was directly depending on snapd as well. To save ourselves trouble, let's make that dependency arch-specific. [Test Case] Build test images on powerpc, those should now succeed. + A quick sanity run of snapd on non-powerpc architectures should also be + performed, making sure that the no-change rebuild for those did not + regress. + [Regression Potential] - None. This is only an arch-specific dependency change which was never - used (as it was not possible to work). + None. This is only an arch-specific dependency change in livecd-rootfs + and maintainer-script changes in snapd. It is highly unlikely that any + of this could have effect in anything other than powerpc (which is not + supported anyway). + + The no-change rebuild of snapd might, as any rebuild, potentially + regress, but the risk is very very low as the previous snapd has been + built and updated recently (so not too many archive changes). [Original Description] livecd-rootfs is used to build our Ubuntu images and it depends on ubuntu-image. With ubuntu-image 1.7 being published to xenial-updates the diff shows that the versioned dependency on snapd was bumped to >= 2.38; which is not satisfiable on powerpc because snapd is not buildable on powerpc with gccgo (vs golang). This affects xenial cloud image builds. Original description: This commit https://git.launchpad.net/livecd- rootfs/commit/debian/control?h=ubuntu/xenial&id=b8b2e343827adb9020d5b71f232c0361bd72685f added a depends on ubuntu-image but that package is not available on xenial for powerpc. So powerpc image builds are failing. :( -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1830823 Title: Ubuntu image builds broken for powerpc on xenial To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/livecd-rootfs/+bug/1830823/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
