Packaging bug prevents install of PXC 5.6

[Matt Griffin]

[Impact]

Package is unusable.

[Development Fix]

None, since Vivid+1 is not yet open.

[Stable Fix]

Fix package build to correctly arch-specific dh_install files in the binary-arch target.

[Test Case]

apt-get install percona-xtradb-cluster-server-5.6

Expected results: success

Actual results:

Setting up percona-xtradb-cluster-server-5.6 (5.6.21-25.8-0ubuntu1) ...
update-alternatives: error: alternative path /etc/mysql/percona-xtradb-cluster.cnf doesn't exist
dpkg: error processing package percona-xtradb-cluster-server-5.6 (--configure):
 subprocess installed post-installation script returned error exit status 2
Processing triggers for libc-bin (2.21-0ubuntu4) ...
Processing triggers for systemd (219-7ubuntu3) ...
Processing triggers for ureadahead (0.100.0-19) ...
Errors were encountered while processing:
 percona-xtradb-cluster-server-5.6
E: Sub-process /usr/bin/dpkg returned an error code (1)

[Regression Potential]

None, since package was unusable before.

[Original Description]

I encountered errors when installing Percona XtraDB Cluster 5.6 in 15.04 from the Universe repo.

Setting up percona-xtradb-cluster-server-5.6 (5.6.21-25.8-0ubuntu1) ...

An initial investigation by Robie Basak from the Ubuntu Server Team at Canonical yielded the following:
Looks like a packaging bug - "dh_install -i" in the binary-arch target should be "dh-install -a", and "dh_installdebconf -i" in the same target shouldn't be there. I've not tested but that looks to be the likely cause to me - meaning that dh_install doesn't put the configuration into the corresponding (arch-dependendant) binary package.

Confirmed on a fresh install of 15.04.

Fixed, retested and pushed to https://github.com/percona/debian-percona-xtradb-cluster-5.6 as https://github.com/percona/debian-percona-xtradb-cluster-5.6/commit/0dbc110ccdc6110601c8d24d4914cd01cdac62b0

Thanks George! We need to prepare an SRU and upload that. I can do it but I'm travelling and will be away for a week. I will try and find some time to get this fixed though. If you can find time in the meantime, it would be helpful if you could please follow https://wiki.ubuntu.com/StableReleaseUpdates#Procedure as either of us can do this. For the upload step in that procedure, upload a debdiff to the bug and subscribe ~ubuntu-sponsors to the bug instead - then any patch pilot rather than just me will be able to pick it up.

Hopefully we'll get there faster that way, but I will still try and get to doing everything ASAP regardless.

[Robie Basak (racb)]

SRU uploaded. Now awaiting review from the SRU team.

Thanks @racb!

Hello Matt, or anyone else affected,

Accepted percona-xtradb-cluster-5.6 into vivid-proposed. The package will build now and be available at https://launchpad.net/ubuntu/+source/percona-xtradb-cluster-5.6/5.6.21-25.8-0ubuntu2 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!

[Matt Griffin (mattgriffin)]

I tested the new package from vivid-proposed and was able to successfully install Percona XtraDB Cluster 5.6.

[Matt Griffin (mattgriffin)]

Tested version 5.6.21-25.8-0ubuntu2

[Dr. Jens Harbott (j-harbott)]

I think there is still something wrong with the packaging here, I get:

~# apt-get install percona-xtradb-cluster-5.6/proposed-updates
Reading package lists... Done
Building dependency tree
Reading state information... Done
Note, selecting 'percona-xtradb-cluster-5.6-dbg' for regex 'percona-xtradb-cluster-5.6'
E: Release 'proposed-updates' for 'percona-xtradb-cluster-5.6-dbg' was not found

and the package percona-xtradb-cluster-5.6 itself seems to be missing.

[Robie Basak (racb)]

@Jens

You want /proposed, not /proposed-updates. See https://wiki.ubuntu.com/Testing/EnableProposed.

[Dr. Jens Harbott (j-harbott)]

Ah, right, that works better now, thanks and sorry for disturbing. ;)
