Bug Description

[Impact]

It is possible to install neither highbank nor armadaxp on Quantal. This is a regression in Quantal, since this worked at release.

[Test Case]

Run the installer using the instructions at https://wiki.ubuntu.com/ARM/Server/Install, except use 12.10 images instead of 12.04.

If successful, the installation should succeed. If this bug still exists, then the installer will fail with the following in /var/log/syslog:

[Regression Potential]

This change affects flash-kernel-installer only, so can only affect d-i. d-i is completely broken for both highbank and armadaxp, so I don't see how it could get worse for these machines. For other machines, a regression would manifest itself as an installer failure only. We have verified that the new linux-version call works as expected in Quantal using network-console, so think that this is unlikely.

Original description:

It appears the installer for highbank is broken because 3.5.0-17 kernel
is running and 3.5.0-18 is the current kernel version which is installed:

  * determine the latest installer kernel version in the target rootfs instead
    of assuming the version is the same as the running kernel (LP: #1084106)
  * drop the "|| true" from the initramfs building code, if we fail here we
    actually dont want to attempt to flash that

Hello Rob, or anyone else affected,

Accepted flash-kernel into quantal-proposed. The package will build now and be available at http://launchpad.net/ubuntu/+source/flash-kernel/3.0~rc.4ubuntu27.1 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 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 change the bug tag from verification-needed to verification-done. If it does not, change the tag to verification-failed. In either case, details of your testing will help us make a better decision.

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

Verified fixed on both highbank and armadaxp, using apt-setup/proposed=true on the kernel command line.

The SRU for this is currently blocked by the verification of bug 1079185 and I'll describe the situation with that verification in that bug.

I feel it is appropriate to bump this bug to Critical for Quantal to reflect the urgency of this SRU.

Justification: this bug is currently rendering all ARM server installers completely unusable in Quantal, and this is a severe post-release regression. Both "Renders the system temporarily or permanently unusable" and "Severely affects applications beyond the package responsible for the root cause" apply here.

The only workaround is to manually mess inside the installer during installation, which is both unacceptable for such an essential default case and renders MAAS unusable.

Therefore, although I will still seek to resolve the blocking verification for bug 1079185, I propose that if this doesn't happen very soon then we revert that fix in -proposed so that only this bug is fixed, so that this can then meet SRU criteria for promotion to -updates (since I can verify this bug is fixed easily) and get this bug resolved in Quantal ASAP.
