[gentoo-user] python-2.7 update: re-emerge of cracklib failed, how can I fix it?

[Jarry]

Hi,
apparently I screwed something during python update, and now
I can not fix my system. This is what I did:

emerge --sync
emerge --ask --update --deep --newuse world

At the end, I have seen:
You should run 'python-updater ${options}' to rebuild Python modules.

So I did, then "emerge --depclean", and that was my mistake:
python2.6 has been unmerged before I switched to python2.7.
Im just surprised python2.6 has been unmerged, when it was
still active and selected python version.

Then by revdep-rebuild I got a lot of error-messages and
at that time I realised something got wrong.

Then I switched to python2.7 (eselect python set python2.7),
and tried revdep-rebuild again. Two packages needed to be
emerged again: libxstl and cracklib. The first got emerged
without a problem, but for cracklib emerge failed with
this messages:

My question is: how can I fix this mess?

Try re-emerging setuptools.

Thanks, this work! So it seems to me, the right procedure is:
1. emerge --update...
2. eselect python set python2.7
3. python-updater ${options}
4. emerge --depclean
5. revdep-rebuild

My mistake was I forgot to run "2."...

... and run 4. and 5. above in the wrong order?

In the e-warning words of --depclean itself:

"* Depclean may break link level dependencies. Thus, it is
 * recommended to use a tool such as `revdep-rebuild` ... "

Agreed, revdep last. I always run depclean with pretend first. If depclean
wants to remove key packages like python, i will often just remove all the
others it has identified manually rather than running it again without
pretend. I also use buildsyspkg.

Hi - you don't give the name of the python version to eselect python set,
you give it the number of the option (usually 1 or 2) next to the version
you want, which you saw when running 'eselect python list'

Re: [gentoo-user] Re: python-2.7 update: re-emerge of cracklib failed, how can I fix it?

[Mr. Jarry]

Apparently, both methods work. But I agree your way is easier...

BTW, when we are at the subject, is it possible to switch to python 3.x,
and get rid of python 2.x completely? I noticed there are still both versions
of python installed: 2.7.1 and 3.1.3...

Possible, yes. Advisable, no. Many (most?) Python 2 scripts will not work
with Python 3, so you really need both interpreters installed.
