[Trusty] iscsitarget-dkms fails to build on linux-generic-lts-xenial kernel

Bug #1612627 reported by fmyoen on 2016-08-12
This bug affects 4 people
Affects Status Importance Assigned to Milestone
iscsitarget (Ubuntu)

Bug Description


 * The iscsitarget-dkms package was not updated to be compatible with the Xenial HWE stack (4.4 kernel) and the driver fails to build.

[Test Case]

 * Install iscsitarget-dkms. If it successfully builds and the module is loadable, the package is fixed.

[Regression Potential]

 * Given that the package currently does not function for the Xenial stack, I believe the regression potential is low. However, the one case would be breaking existing 3.13.x deployments of 14.04; in my testing, the DKMS package successfully builds there as well.


1) The release of Ubuntu you are using, via 'lsb_release -rd' or System -> About Ubuntu
# lsb_release -rd
Ubuntu 14.04.5 LTS
Release: 14.04

2) The version of the package you are using, via 'apt-cache policy pkgname' or by checking in Software Center
# apt-cache policy iscsitarget-dkms
  Version table:
*** 0

        100 /var/lib/dpkg/status 0
        500 http://...archive.ubuntu.com/ubuntu/ trusty/universe amd64 Packages

3) What you expected to happen
iscsitarget-dkms module should build successfully. iscsitarget service should start.

4) What happened instead
iscsitarget-dkms module fail to build. iscsitarget service fail to start:

# service iscsitarget restart
* Removing iSCSI enterprise target devices: [ OK ]
* Starting iSCSI enterprise target service
modprobe: FATAL: Module iscsi_trgt not found.

Thank you for reporting this bug! It seems we need to add/backport the Xenial changes for 4.3/4.4 compatibility. I'm working on that now.

Hello, I have provided a build of iscsitarget at: https://launchpad.net/~nacc/+archive/ubuntu/lp1612627 which I believe has the correct fixes backported. If you could give it a test and report back the results, that would be great!

How long before the fix is available through repositories?

Nish Aravamudan (nacc) wrote :

@msa1: no one has reported back if the issue is fixed by testing my PPA, so no timeline until that is done.

Hello fmyoen, or anyone else affected,

Accepted iscsitarget into trusty-proposed. The package will build now and be available at https://launchpad.net/ubuntu/+source/iscsitarget/ 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 add a comment to this bug, mentioning the version of the package you tested, and change the tag from verification-needed to verification-done. If it does not fix the bug for you, please add a comment stating that, and 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!
