Ok, finally snapd built successfully for all arches.

@rcj could you try building xenial powerpc images and seeing if snapd
still fails to install properly?

I'll ask cachio or someone else from the snapd team to do a quick sanity
test of the snapd rebuilt binaries on other arches to make sure there's
no regressions introduced through dependencies.

Hello Robert, or anyone else affected,

Accepted snapd into xenial-proposed. The package will build now and be
available at https://launchpad.net/ubuntu/+source/snapd/2.39.2ubuntu0.1
in a few hours, and then in the -proposed repository.

Please help us by testing this new package.  See
https://wiki.ubuntu.com/Testing/EnableProposed for documentation on how
to enable and use -proposed.  Your feedback will aid us getting this
update out to other Ubuntu users.

If this package fixes the bug for you, please add a comment to this bug,
mentioning the version of the package you tested and change the tag from
verification-needed-xenial to verification-done-xenial. If it does not
fix the bug for you, please add a comment stating that, and change the
tag to verification-failed-xenial. In either case, without details of
your testing we will not be able to proceed.

Further information regarding the verification process can be found at
https://wiki.ubuntu.com/QATeam/PerformingSRUVerification .  Thank you in
advance for helping!

N.B. The updated package will be released to -updates after the bug(s)
fixed by this package have been verified and the package has been in
-proposed for a minimum of 7 days.

[Bug 1830823] Re: Ubuntu image builds broken for powerpc on xenial

2019-06-26 Thread Łukasz Zemczak
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.

If I understand launchpad-buildd[1] correctly, snapd will be installed
regardless of livecd-rootfs' dependencies.  The fix needs to be in snapd
for powerpc on xenial.  I confirmed that with a -proposed build with
livecd-rootfs 2.408.50 we will still try to install snapd and fail the
build as before.

I've marked this as verification failed as the build is not fixed by
this change.  The livecd-rootfs change looks safe enough but does not
address root cause and as such we can not complete a build to verify
this change doesn't break things further; all we can say is that it
doesn't address root cause.

I have just been told by Rob that powerpc builds are still failing with
the new livecd-rootfs as apparently some other package still pulls in
snapd. I guess we might have to fix this in snapd then.

@mvo Could you take a look and see what's up with the new dummy snapd
package for powerpc?

[Bug 1830823] Re: Ubuntu image builds broken for powerpc on xenial

2019-05-30 Thread Steve Langasek
livecd-rootfs still doesn't work on powerpc, because now that we are not
depending on ubuntu-image, python3-yaml is not pulled in as an indirect
dependency, leading to runtime failures.

Will reupload a further fix.

autopkgtests pass, the only delta is to drop a dependency on one
architecture, considering verified.

to enable and use -proposed.  Your feedback will aid us getting this
update out to other Ubuntu users.

If this package fixes the bug for you, please add a comment to this bug,
mentioning the version of the package you tested and change the tag from
verification-needed-xenial to verification-done-xenial. If it does not
fix the bug for you, please add a comment stating that, and change the
tag to verification-failed-xenial. In either case, without details of
your testing we will not be able to proceed.

...actually we can't really switch the ubuntu-image dependency (it's an
arch: all package, duh). But we can get rid of the ubuntu-image dep in
livecd-rootfs on powerpc.

[Bug 1830823] Re: Ubuntu image builds broken for powerpc on xenial

2019-05-29 Thread Steve Langasek
Since snaps are not supported on powerpc, it also doesn't make sense to
have an ubuntu-image package that depends on snapd on this architecture.
It is still potentially interesting to have ubuntu-image available on
all archs for the 'ubuntu-image classic' use case, so in terms of
overall direction I think it's better to have ubuntu-image drop its dep
on snapd on powerpc and NOT have livecd-rootfs drop its dep on ubuntu-
image on powerpc, in addition to having snapd available again on powerpc
as a dummy package.

It is very unlikely that we will ever SRU back to xenial any support for
actual ubuntu-image classic images on powerpc, but just in case this
would future-proof it.

In the meantime, as per Steve's valid recommendation, I'll make the
snapd build dependency for 1.7 in xenial optional for powerpc.
