Python 2.7 missing in debian_defaults

[Dag Odenhall]

Maverick has a package for Python 2.7. When installed, some APT operations show this:

INFO: using unknown version '/usr/bin/python2.7' (debian_defaults not up-to-date?)

$ cat /usr/share/python/debian_defaults
[DEFAULT]
# the default python version
default-version = python2.6

# all supported python versions
supported-versions = python2.6

# formerly supported python versions
old-versions = python2.3, python2.4, python2.5

# unsupported versions, including older versions
unsupported-versions = python2.3, python2.4, python2.5

Why this bug is still on 'new'? It seams trivial.

fixed in natty, nothing to fix in maverick

[F. Hantho (hantho)]

Sorry if I am missing something obvious but what do you mean "nothing to fix in maverick"?

1) that we should ignore it because it doesn't matter?
2) that the fix doesn't apply to maverick?
3) that the bug is not in maverick?
4) ???

For the record: I'm on a fully updated maverick, and the bug is still there.

Hello Hantho and others

I just had the same 'exception(?)' when taking the command 'sudo apt-get upgrade'. I'd suppose this is no bug, due it lead not into an error while the upgrade process ran, but it's IMHO a lack, missing feature, whatever.

As Dag Odenhall posted in the opening entry, he added the content of '/usr/share/python/debian_defaults'. It seems, that someone can avoid the issue, by replacing the line with the stuff from here:

# all supported python versions
supported-versions = python2.5, python2.6, python3.0 (or whatever Version)

------------------
DON'T:
So if any of newbies read this post. Please don't set python3.0 as standard! When I tried this, it lead into a bunch of bad errors. It seems to me, that a lot of python programs, packages and installers still aren't made to run this version.

# the default python version
default-version = python3.0
-------------------

But one thing is, that I also don't understand what 'nothing to fix in maverick ' means. Why isn't e.g. my freshly installed python2.7 not in the list of the supported versions from debian_defaults? Unfortunately, I still don't understand the dependencies of the mentioned file. Where can I get more info?

Best regards to all,
Sebastian

@Matthias: Shouldn't python2.7 be added in the maverick file /usr/share/python/debian_defaults ? The package python2.7 is in the official repositories as far as I can see.

$ cat /usr/share/python/debian_defaults
[DEFAULT]
# the default python version
default-version = python2.6

# all supported python versions
supported-versions = python2.6

# formerly supported python versions
old-versions = python2.3, python2.4, python2.5

# unsupported versions, including older versions
unsupported-versions = python2.3, python2.4, python2.5

Is there any drawbacks if one adds python2.7 to the list of supported python in the maverick file /usr/share/python/debian_defaults as @Savvas suggested?

Just got this while upgrading my 10.10 server to 11.04...a lot of times...

I also notice that when I attempted to install ubuntu-tweak via the .deb, Software Center informs me that it requires Python 2.7, but no package provides that (or some similar message), despite the fact that I can see Python 2.7 via an aptitude search.

After installing Python 2.7 via aptitude, I get the same message as others every time I do a software install.

Ubuntu 10.10, BTW, so I'm also not sure what is meant by "nothing to fix for Maverick".
