[Bug 862129] Re: samba postrm depends on packages not guaranteed to be configured
Analysis of the upgrade logs and further discussion on IRC shows that it's infeasible to fix this in samba. The problem arises when perl- modules is unpacked without libperl5.12/perl-base, and then samba is unpacked. Moving the update-inetd code from the postrm to the prerm may help in some cases, but not in this one, because whichever maintainer script tries to call update-inetd, the modules will be unavailable to perl at that point. Fixing update-inetd to be more robust (i.e., to not require perl- modules) would help for the future, but would not help for the present upgrade problems. I think the only way to fix this reliably is via update-manager. ** Package changed: samba (Ubuntu Oneiric) = update-manager (Ubuntu Oneiric) ** Changed in: update-manager (Ubuntu Oneiric) Assignee: (unassigned) = Michael Vogt (mvo) -- You received this bug notification because you are a member of Ubuntu Server Team, which is subscribed to samba in Ubuntu. https://bugs.launchpad.net/bugs/862129 Title: samba postrm depends on packages not guaranteed to be configured To manage notifications about this bug go to: https://bugs.launchpad.net/samba/+bug/862129/+subscriptions -- Ubuntu-server-bugs mailing list Ubuntu-server-bugs@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-server-bugs
[Bug 862129] Re: samba postrm depends on packages not guaranteed to be configured
Given the number of dupes, shouldn't this be raised to a Critical level? This has now broken dozens of upgrades that we know about, and I'm sure many more that haven't bothered to report it. Robie's suggestion to simplify update-inetd, given that these are very primitive elements, seems the best approach for a quick fix while the nature of the dependency problem is considered. -- You received this bug notification because you are a member of Ubuntu Server Team, which is subscribed to samba in Ubuntu. https://bugs.launchpad.net/bugs/862129 Title: samba postrm depends on packages not guaranteed to be configured To manage notifications about this bug go to: https://bugs.launchpad.net/samba/+bug/862129/+subscriptions -- Ubuntu-server-bugs mailing list Ubuntu-server-bugs@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-server-bugs
[Bug 862129] Re: samba postrm depends on packages not guaranteed to be configured
I discussed this bug at length with Adam on Friday afternoon. Adam is on vacation now so I'll try and reproduce my memory and conclusions from this conversation. Some thoughts from that discussion: 1) perl-modules (which provides File::Temp) seems to spend a lot of time unconfigured in the upgrade process. Adam pointed out that this is an anomaly given how much packages depend on Perl in general, and that the problem might be considered to be with the Perl transition and fixing this may be one approach. Take a look at VarLogDistupgradeTermlog.gz in bug 856309 for example - perl and perl-modules are unpacked but not configured in the entire session. I understand that this still complies with policy; the way I see the problem is that perl-modules and update- inetd still need to export some kind of mechanism to make them usable within maintainer scripts for them to be useful. 2) If update-inetd is supposed to be able to be used from within maintainer scripts, what is the correct way of doing so? If it is supposed to be used from a postrm and thus cannot rely on perl-modules to be configured, then is the bug really that update-inetd is depending on things that it cannot? 3) If we could change update-inetd to not depend on Perl modules that may not be configured, then this particular bug wouldn't be an issue any more. It looks like we may only need tempfile anyway, which is in debianutils and Essential. The advantage of File::Temp seems to be portability, which isn't an issue for us as we guarantee tempfile to always be available. update-inetd also appears to need File::Copy so I'll need to check this, but in any case would the approach of removing dependencies by bringing minimal implementations into update-inetd be acceptable? ** Also affects: update-inetd (Ubuntu) Importance: Undecided Status: New ** Also affects: perl (Ubuntu) Importance: Undecided Status: New -- You received this bug notification because you are a member of Ubuntu Server Team, which is subscribed to samba in Ubuntu. https://bugs.launchpad.net/bugs/862129 Title: samba postrm depends on packages not guaranteed to be configured To manage notifications about this bug go to: https://bugs.launchpad.net/samba/+bug/862129/+subscriptions -- Ubuntu-server-bugs mailing list Ubuntu-server-bugs@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-server-bugs

[Bug 862129] Re: samba postrm depends on packages not guaranteed to be configured
And it occurs to me that I maintain a package that calls update-inetd in postrm too. Hrm. Did it used to fail more gracefully when it wasn't fully configured?

but doesn't it seem silly to have an enabled service in inetd that references binaries that no longer exist on disk? Well, it's possible to use a different marker for package-level disabling vs. admin-level disabling of a service... note that the postrm *always* disables it when we're not purging, too.

[Bug 862129] Re: samba postrm depends on packages not guaranteed to be configured
I'm thinking along the lines of the attached patch (untested). Some questions: 1) Is this the right approach? 2) Is dpkg-query the right way to get the status of the update-inetd package? 3) What about triggers-awaiting and triggers-pending? What should the behaviour be in these cases? Is it OK to treat update-inetd as not available in these cases? 4) I've tried manually deconfiguring update-inetd and perl-modules (by purging and then unpacking only) before purging samba, but that doesn't trigger the problem. Any way I try the upgrade case, dpkg refuses because update-inetd (intentionally) isn't configured.
