[Bug 364608] Re: pymol menu bar does not show up after upgrade to jaunty

2009-04-23 Thread Michael Vogt
Thanks for the logs. I just checked and:
...
Selecting previously deselected package python2.6-minimal.

Unpacking python2.6-minimal (from
.../python2.6-minimal_2.6.2~rc1-0ubuntu2_i386.deb) ...

Processing triggers for man-db ...

Setting up python2.6-minimal (2.6.2~rc1-0ubuntu2) ...

Linking and byte-compiling packages for runtime python2.6...

INFO: using unknown version '/usr/bin/python2.6' (debian_defaults not
up-to-date?)

...

So it looks like python did link/byte compile but for some reason the
pymol stuff did not get linked.

2009-04-23 Thread Michael Vogt
I looked a bit more and the chain of events in the log is:
1. python2.6-minimal gets install and calls rtinstall scripts - at this point 
python2.6 is not yet marked as supported in /usr/share/python/debian_defaults 
2. new python-support gets installed and links for all supported runtimes
3. pymol gets unpacked 
4. python-minimal gets installed, now python2.6 is supported and that triggers 
python-support to byte-compile again
5. pymol gets configured

Now if the links are missing somewhere here is a bug that is not yet
fixed.

2009-04-23 Thread Michael Vogt
I was not able to reprouce the failure here with a normal upgrade test, but I 
get (line number from my upgrade in the brackets):
 - python-support (326)
 - pymol (368)
 - python2.6-minmal (376)
 - python-minimal (382)
So I suspect the problem is order dependant.

After reading the report again it turns out the problem is python-pmw
that triggers python-central bug #357884 - this got fixed afterwards but
its a problem for people who upgraded with the RC (the binary got
published at the 17.04).

It only affects people who upgraded to RC (or before) and only python
package that have no new version between intrepid-jaunty and use

Running pycentral rtinstall python2.6 again does also fix the problem of
course. Doing that automatically is a bit tricky, but we could just run
it for everyone again

2009-04-23 Thread Scott Kitterman
I think if that would fix it we should do it.

I do recall that for the python-qt-dbus (or dbus-qt, I can never remember) 
bug that led to the python-central fix , I tried that and it didn't fix it. 
 Was there something unique about that package that caused that packed not 
to get fixed and are there other packages in that catagory?

I have a vague recollection that it's paths were somewhat odd because the 
Debian maintainer had started work moving the package to python-support.

I think we ought to update the release note now and consider running it for 
everyone once we know if covers all cases.  If we are going to run a 'fix' 
for everyone we ought to make sure it's comprehensive first so we only do 
it once.

[Bug 364608] Re: pymol menu bar does not show up after upgrade to jaunty

2009-04-22 Thread Steve Langasek
Documented at
https://wiki.ubuntu.com/JauntyJackalope/ReleaseNotes#python ImportError
with systems upgraded before Ubuntu 9.04 release candidate:

A bug in the python packages present in jaunty prior to the Ubuntu 9.04
release candidate caused python modules to fail to be registered for use
with the current python version, python 2.6. This problem appears as an
import error, e.g:

 ImportError: No module named foo

even though the package providing the module package is installed.

To correct this, run the command:

 sudo dpkg-reconfigure python-foo

for each python-foo package providing an affected module.

Thanks for your bugreport.

Could you please attach /var/log/dist-upgrade/* and
/var/log/apt/term.log ? I would like to diagnose this a bit more to see
if I can figure out how broad the scope of the problem is.

It is weird it only imports Pmw to python2.5. I have python-pmw
1.3.2-3 installed. Pymol worked fine even yesterday morning with the jaunty RC, 
there were a couple of python upgrades since then. I try reinstalling 
python-pmw maybe it helps.

[Bug 364608] Re: pymol menu bar does not show up after upgrade to jaunty

2009-04-21 Thread Steve Langasek
notes on getting this release-noted, from IRC:

17:30  ScottK The issue was the upgrade of the package happening before 
python2.6 had turned into a supported  version, so the module didn't get 
symlinked for 2.6.
17:31  ScottK I suspect (but cannot prove) that an indeterminate number of 
people who upgraded before the fix have an indeterminate number of broken 
python packages.
17:32  ScottK Caveated to people who upgraded before RC.
17:34  slangasek should dpkg-reconfigure do the job?  (calls the postinst, 
saves a download)
17:36  ScottK I'm not sure.  Most of the symlink magic is done in postinst, 
so it should.
17:37  ScottK The thing to key off of is ImportError: No module named Pmw 
so in the release note we can say if the error is ImportError: No module named 
foo then reconfigure/reinstall python-foo.
17:37  ScottK Dunno if that's too complex or not, but it may save us some 
bugs and users some frustrations.
17:38  ScottK Given that the problem should be limited to people that 
upgraded pre-RC they should in theory be able to deal with it.
