Justification: breaks unrelated software

Hey.
CCing d-d since there seems some further deeper problem with the t64
transition (namely lib files getting lost, when "downgrading" i.e.
reverting).
Earlier tonight I've upgraded this day’s packages which included
numerous that made the t64 transition (see the attached aptitude log
for the whole process, first the upgrade, and then "bi-secting" to
find the culprit).
Immediately afterwards, starting GUI programs from the still running
desktop environment caused failures like:
$ evince
(evince:17537): GLib-GIO-CRITICAL **: 04:18:22.610: g_settings_schema_source_lookup: assertion 'source != NULL' failed
(evince:17537): GLib-GIO-CRITICAL **: 04:18:22.610: g_settings_schema_source_lookup: assertion 'source != NULL' failed
(evince:17537): GLib-GIO-ERROR **: 04:18:22.658: No GSettings schemas are installed on the system
Trace/breakpoint trap
$ gedit
(gedit:17585): GLib-GIO-ERROR **: 04:18:35.012: No GSettings schemas are installed on the system
Trace/breakpoint trap
$
I suspected a reboot might be needed but after that even the display
manager didn't start anymore.
I saw errors like:
Feb 29 02:51:14 heisenberg kernel: traps: at-spi-bus-laun[17935] trap int3 ip:7fdceec49587 sp:7ffd0acdade0 error:0 in libglib-2.0.so.0.7800.4[7fdceec05000+99000]
Feb 29 02:51:52 heisenberg kernel: traps: at-spi-bus-laun[17941] trap int3 ip:7f52e53ee587 sp:7ffcc69b0fc0 error:0 in libglib-2.0.so.0.7800.4[7f52e53aa000+99000]
My first guess was glib, so I downgraded that (everything from the source
package), but that didn't help.
As you can see from the aptitude log, I then moved on downgrade further
of the previously upgraded packages, several times I've rebooted in-
between (e.g. after downgrading things like *pam* and *systemd*).
Along the way I saw the most weirdest effects:
- logind was apprently in some bogus state, which I think might
have been the reason, why X/the display manager remained black/hung for
several minutes:
Feb 29 03:37:21 heisenberg lightdm[139886]: Failed to get list of logind seats: GDBus.Error:org.freedesktop.DBus.Error.TimedOut: Failed to activate service 'org.freedesktop.login1': timed out (service_start_timeout=25000ms)
- At some point, when installing packages via aptitude
# aptitude
<here I started the upgrade or downgrade>
Performing actions...
<here it hang for several minutes... no real CPU/disk load>
And it also hung at the end shortly after finishing the
upgrade/downgrade.
- When downgrading packages that had a t64 transition, sometimes
the lib file was gone.
I.e. I removed the *t64 package and re-installed the old one
and then the .so file for libapt-pkg6.0 and libpam0g was missing.
How can that happen?
Eventually I downgraded the gcr/gck stuff, and then it worked again.
From that I went forward and upgrade all the various packages again, to
see where the problem actuall is.
Turns out, it's probably actually libglib.
When I install the first time libglib2.0-0t64 (and purge libglib2.0-0),
things start to break apart.
When I re-install libglib2.0-0t64, things work again (it seems regardless
of the gcr/gck stuff).
Long story short:
@glib maintainers:
- there's something wrong with the transition (unless even that need for
the re-install is already a sign for some deeper issues)
@d-d:
- How can it happen that purge *t64 packages and at the same time install
the previous package, and then the so file is missing?
I mean it's clear that they use the same name, but shouldn't DPKG handle
the cleanly?
Thanks,
Chris
PS: I'll attach the aptitude log only to the bug and not to d-d, in
order not to spam so many people with it.
It's probably anyway uselesss, but might help to find out why
downgrading gck/gcr stuff helped first, without re-installing the
glib package.
