update linux-base on xenial and earlier

[Thadeu Lima de Souza Cascardo]

[Impact]

After some changes on linux package on bionic, linux-azure-edge and linux-hwe-edge, which are based on that package, now require a linux-base that provides linux-update-symlinks and linux-check-removal. Using the latest version also means translations will be present.

[Test Case]

Installing the latest linux-azure-edge will fail the config stage because maintainer scripts call into non-existing linux-update-symlinks and linux-check-removal.

Test result: It works with xenial kernels and fixes the problem with hwe-edge.

[Regression Potential]

New functions on perl module are tested during build time. It could break symlinks creation for other kernels. perf bash completion is not distributed, so does not conflict with linux-tools-common. Older kernels still have their links working.

[Tyler Hicks (tyhicks)]

cascardo asked me to sponsor his upload to xenial-proposed. I've compare the build logs between the 4.0ubuntu1 version currently in xenial to the build logs from his 4.5ubuntu1~16.04.1 change. The build logs are clean with no surprises. I also compared the binary packages and was able to confirm his assertion that the perf bash completion file is not distributed.

Outside of the added linux-update-symlinks and linux-check-removal commands which motivate this upload, there's only one other notable code change:

   * Add image_stem() and read_kernelimg_conf() functions to Perl module

Those two new functions are only used by the new linux-update-symlinks command.

I think this is safe to SRU to Xenial and, therefore, have sponsored the upload.

I can confirm this fixes 4.17-rc2 from mainline ppa for xenial. Thank you!

[Launchpad Janitor (janitor)]

Status changed to 'Confirmed' because the bug affects multiple users.

[RBL Admin (rbladmin)]

Fixed installing mainline PPA 4.17.0-041700rc2-generic on 16.04.4.

[Andy Whitcroft (apw)]

We will not need this in artful as we will not backport kernels there which need it.

The verification of the Stable Release Update for linux-base 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.

I tested upgrades from xenial to bionic or linux-hwe-edge upgrades from xenial-updates to xenial-proposed after a linux-base upgrade to the one in xenial-proposed.

[Marcelo Cerri (mhcerri)]

I have tested the the current linux-base in trusty-proposed (4.5ubuntu1~14.04.1) and I couldn't find any issues.

I tested the following scenarios:

- Generic kernel update with the new linux-base.
- Installation of linux-azure 4.15 with the new linux-base.
- Upgrade from trusty to xenial.

I used a local KVM instance for all the tests.

[Jason Pereira (jasondpereira)]

I am still having this issue while performing a fresh install of Xenial.

[mike (xazes123)]

We have still this issue with fresh install Xenial too.

[Research Computing (rcgop)]

Ditto. Netinstalls are broken and the installer ignored the suggested workaround in our kickstart:

preseed d-i base-installer/kernel/image string linux-image-4.4.0-142-generic

Marking the devel release fixed as well, since backport versions are by definition already fixed there.
