The problem is not with python-central itself but with the version of
python-minimal that is used in combination.
The problem can only be reproduced in etch which has python-minimal
2.4.3-11. The version 2.4.4-1 from sid has an updated
/usr/share/python/debian_defaults which knows python2.5:
$ cat /usr/share/python/debian_defaults
[DEFAULT]
# the default python version
default-version = python2.4
# all supported python versions
supported-versions = python2.4
# formerly supported python versions
old-versions = python2.3
# unsupported versions, including older versions
unsupported-versions = python2.3, python2.5
Whereas etch doesn't:
$ cat /usr/share/python/debian_defaults
[DEFAULT]
# the default python version
default-version = python2.4
# all supported python versions
supported-versions = python2.3, python2.4
# formerly supported python versions
#old-versions = python2.3
So the proper fix is to make sure that a good version of python-minimal is
setup before the install of python2.5. So the bug is in python2.5-minimal
and I'm reassigning it.
Apart from that, python-central still does very weird things in the way it
handles the list of supported runtimes.
The function get_supported_runtimes() has been modified to accept a
parameter "with_unsupported" which defaults to True and it's only used
with explicit assignation to "True". So I believe the default value should
have been false. However the action "RuntimeInstall" calls the function
without indicating with_unsupported=True which means that if the default
value is changed to False, this failure will happen again even if the
good version of python-minimal is installed.
for rt in get_installed_runtimes():
if rt.name == self.rtname:
self.runtime = rt
break
if not self.runtime:
self.error('installed runtime %s not found' % self.rtname)
I'll prepare an NMU of python 2.5 to fix the RC problem. And I'm downgrading
this bug so that this inconsistent handling of installed runtimes can be fixed
later.
