Package: python-central
Version: 0.6.16+nmu1
Severity: important
Whereas many Debian packages rely on Python and
Whereas such packages may rely on *python-central* to check for a supported
Python version and
Whereas the stability of such packages depends on periodic, automated updates
and
Whereas the stability of Debian Linux as a whole depends upon such packages and
Whereas the check for the installed Debian default version of Python fails
subsequent to *update-alternatives* even when the alternative selected is the
current approved and acceptable version and
Whereas *update-alternatives* is currently supported and
Whereas *update-alternatives* is a component of *dpkg*, which is currently
supported, and
Whereas *update-alternatives* is a time-honored technique for selecting Python
versions and
Whereas this technique is widely discussed in the documentation for *dpkg* and
on the popular help sites for Debian and downstream distributions and has been
for years and
Whereas this technique is not deprecated and
Whereas suppressing this technique would be impractical given the vast folklore
behind it and
Whereas a trivial change to *python-central* avails to allow *update-
alternatives* to be used to choose between valid default versions of Python and
Whereas this might answer many Debian bugs including #571231 against python-
gst0.10, #485393 and #551141 against python-central, and #573315 against
Python2.6 and
Whereas it might also answer a vastly greater number of questions on the
popular help sites for Debian and dowstream distributions and
Whereas *python-central* already accommodates one level of indirection in that
/usr/bin/python may be a symbolic link and
Whereas accommodating only the one more level of indirection through
/etc/alternatives that *update-alternatives* introduces is not a computational
burden
Now, therefore, I humbly suggest that this change be made.
