initramfs-tools exception during pm.DoInstall with do-release-upgrade from 16.04 to 18.04

I thought this was mentioned today and/or was being worked on. To check with adam.

This bug is missing log files that will aid in diagnosing the problem. While running an Ubuntu kernel (not a mainline or third-party kernel) please enter the following command in a terminal window:

apport-collect 1766727

and then change the status of the bug to 'Confirmed'.

If, due to the nature of the issue you have encountered, you are unable to run this command, please add a comment stating that fact and change the bug status to 'Confirmed'.

This change has been made by an automated script, maintained by the Ubuntu Kernel Team.

This is not a duplicate, do not mark as duplicate. This appears to be s390x specific zipl integration.

It is not a bug with the release upgrade code rather it is a failure of a specific package during the release upgrade.

This bug was fixed in the package s390-tools - 2.3.0-0ubuntu3

This will likely break with linux-hwe-edge on xenial as well. Hence, requesting SRU for xenial with the attached debdiff.

Cascardo asked me to review and sponsor the s390-tools debdiff to xenial-proposed. While I don't have a an easy way to test this change myself, I've verified that it matches the changes from Adam Conrad in Bionic and that the change looks reasonable. Cascardo ensured me that an SRU is not needed in Artful since linux-hwe-edge is not present there. I'm sponsoring this change to xenial-proposed.

Hello John, or anyone else affected,

Accepted s390-tools into xenial-proposed. The package will build now and be available at https://launchpad.net/ubuntu/+source/s390-tools/1.34.0-0ubuntu8.6 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!

This bug is awaiting verification that the kernel in -proposed solves the problem. Please test the kernel and update this bug with the results. If the problem is solved, change the tag 'verification-needed-bionic' to 'verification-done-bionic'. If the problem still exists, change the tag 'verification-needed-bionic' to 'verification-failed-bionic'.

If verification is not done by 5 working days from today, this fix will be dropped from the source code, and this bug will be closed.

See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed. Thank you!

I was able to successfully test this with proposed enabled.
Started with 16.04 kernel 4.4 - to 16.04 HWE Kernel - via do-release-upgrade to 18.04.
For details see also attached cmd log.
Changed tags accordingly.

The verification of the Stable Release Update for s390-tools has completed successfully and the package has now been released to -updates. Subsequently, the Ubuntu Stable Release Updates Team is being unsubscribed and will not receive messages about this bug report. In the event that you encounter a regression using the package from -updates please report a new bug using ubuntu-bug and tag the bug report regression-update so we can easily find any regressions.

This bug was fixed in the package s390-tools - 1.34.0-0ubuntu8.7

s390-tools (1.34.0-0ubuntu8.7) xenial; urgency=low

  * No-change rebuild against the -security pocket to let this be
    copied out to -security as the kernels it supports are destined
    to go to -security at some point.
