Bug Description

Binary package hint: system-tools-backends

Lucid ships with system-tools-backends 2.9.4-0ubuntu1, which is an upstream development version considered as unstable, and which suffers form several serious bugs. Maverick now has 2.10.0 synced from Debian, with very limited changes (bugfixes only). It fixes bug 534154, bug 533870, bug 542183, and bug 546873.

Summary of the bugs:
Bug 534154: crash on amd64
Bug 533870: another crash on amd6' preventing from editing user's own Real name
Bug 542183: changing UID doesn't work
Bug 546873: very long delays with no feedback when applying changes

Attached is the diff between Lucid and Maverick versions.

I've marked the main task invalid since this is already in Maverick, but approved the Lucid task so that this bug remains open.

Thanks for this suggestion! I think that the easiest way to move this forward (i.e. the way most likely to be accepted) would be to prepare a targeted backport of just the bug-fixes, without things like whitespace changes, translation updates (which would need to go in language packs for an Ubuntu stable release anyway), etc. I agree that 2.10.0 doesn't seem to change much beyond the bug-fixes, but a diff that's absolutely clearly "bug fixes only" would be easier to get through the stable release update process. See for details.

Are you OK with preparing this, or do you need assistance?

Seriously, I've moved on to other things since Lucid has been released - glad to know SRUs are considered even when they are that old, though! ;-)

The only translation change between Lucid and Maverick package is in one file and for two strings, so definitely not something to care about. If somebody wants to prepare a new package for SRU, that's cool, but given how hard it was to get somebody work on this, I don't think it will be quicker than backporting the Maverick package.

This is basically the upstream diff, minus autotools cruft and translations, which looks much more palatable

Milan Bouchet-Valat (nalimilan) wrote :

Thanks Chris! But we really don't need to backport 2.10.1, 2.10.0 will be enough. 2.10.1 only brings in a few improvements that are used by the gnome-system-tools 2.32, which are not in Lucid. This removes most of the changes (in terms of lines of code), which makes the SRU even safer.

Looks ok, please upload. Thanks, Milan and Chris!

I've prepared an SRU for lucid based on a minimal backport from 2.10.0. See the attached debdiff.

Thanks for the diff!

Looks good to me, except that the change log line:
- Identify users and groups by login instead of UID (LP: #533870, LP: #542183)
is wrong: Bug 533870 is a crash on amd64 too, not a login vs. UID issue.

Thanks for taking a look. Unfortunately, I have already uploaded it to -proposed.
I don't think it's worth another upload just to fix the changelog.

No, I don't think it is. ;-) As long as the right number is listed...

For the record, you can just upload again with the fixed changelog
(same version number), I'll reject the previous one once I get to
reviewing the queue.

Ah! I didn't know I could do that. I just re-uploaded with a fixed changelog. Thanks!

Accepted system-tools-backends into lucid-proposed, the package will build now and be available in a few hours. Please test and give feedback here. See for documentation how to enable and use -proposed. Thank you in advance!

Any testers of the lucid-proposed package? As this has been in -proposed for a long time already, I'll remove the proposed package soon if there is no feedback. Thank you!

Marc Deslauriers (mdeslaur) wrote :

I have successfully tested the package in -proposed. With the updated package, I was able to add and remove users, change parameters, etc.
