Python upgrade breaks eyeD3

[Tim Heaney]

Binary package hint: eyed3

I built Python 2.6.1 from source and installed it in /usr/local/bin/python. The original Python is still in /usr/bin/python.

  tim@calvin:~$ /usr/bin/python -V
  Python 2.5.2
  tim@calvin:~$ /usr/local/bin/python -V
  Python 2.6.1

This broke the eyeD3 command-line program, which failed with

  tim@calvin:~/Music/JuneStar$ eyeD3 released.mp3
  Traceback (most recent call last):
    File "/usr/bin/eyeD3", line 32, in <module>
      from eyeD3 import *;
  ImportError: No module named eyeD3

That's because /usr/bin/eyeD3 has a shebang line of

  #!/usr/bin/env python

and, of course, that's now finding the wrong version of Python

  tim@calvin:~$ /usr/bin/env python -V
  Python 2.6.1

Calling with the correct version of Python fixes it.

  tim@calvin:~/Music/JuneStar$ /usr/bin/python /usr/bin/eyeD3 released.mp3

  ID3 v2.3:
  title: Released artist: Andrew Grimm
  album: Recordings year: None
  track: genre: Folk (id 80)

Thus changing the shebang line of /usr/bin/eyeD3 to /usr/bin/python fixes it.

This is essentially the same issue as #199134

  https://bugs.launchpad.net/system-tools-backends/+bug/199134

but not as severe, since it's an user application that is broken, rather than a system tool. And it's a matter of missing dependencies, not a broken interpreter as freedesktop.org so unkindly summarized the upstream version of that bug

  http://bugs.freedesktop.org/show_bug.cgi?id=16642;

I reported this issue to the developer of eyeD3 back in October when it first happened to me (with Python 2.6, not 2.6.1), but I could not seem to convince him that it's a mistake to use env this way in system scripts.

But it's not really an issue with eyeD3 per se, but with the .deb that installs it. Shouldn't it re-write the shebang line to /usr/bin/python? Indeed, on my system all of the following are bugs waiting to happen:

  /usr/bin/getnonfreefonts #!/usr/bin/env perl
  /usr/bin/getnonfreefonts-sys #!/usr/bin/env perl
  /usr/bin/gtk-builder-convert #!/usr/bin/env python
  /usr/bin/gtkcdlabel.py #!/usr/bin/env python
  /usr/bin/hp-align #!/usr/bin/env python
  /usr/bin/hp-check #!/usr/bin/env python
  /usr/bin/hp-clean #!/usr/bin/env python
  /usr/bin/hp-colorcal #!/usr/bin/env python
  /usr/bin/hp-fab #!/usr/bin/env python
  /usr/bin/hp-firmware #!/usr/bin/env python
  /usr/bin/hp-info #!/usr/bin/env python
  /usr/bin/hp-levels #!/usr/bin/env python
  /usr/bin/hp-makecopies #!/usr/bin/env python
  /usr/bin/hp-makeuri #!/usr/bin/env python
  /usr/bin/hp-print #!/usr/bin/env python
  /usr/bin/hp-probe #!/usr/bin/env python
  /usr/bin/hp-scan #!/usr/bin/env python
  /usr/bin/hp-sendfax #!/usr/bin/env python
  /usr/bin/hp-setup #!/usr/bin/env python
  /usr/bin/hp-systray #!/usr/bin/env python
  /usr/bin/hp-testpage #!/usr/bin/env python
  /usr/bin/hp-timedate #!/usr/bin/env python
  /usr/bin/hp-toolbox #!/usr/bin/env python
  /usr/bin/hp-unload #!/usr/bin/env python
  /usr/bin/invest-chart #!/usr/bin/env python
  /usr/bin/perltex #! /usr/bin/env perl
  /usr/bin/rss-glx_install #!/usr/bin/env perl
  /usr/bin/texdoctk #!/usr/bin/env perl
  /usr/bin/tomboy #!/usr/bin/env bash
  /usr/bin/tomboy-panel #!/usr/bin/env bash

In fact, I guess in my case, the Python ones have already happened. Let's see

  tim@calvin:~$ /usr/bin/gtkcdlabel.py
  python-id3 not found - diabling MP3/ID3 support
  python-cddb not found - diabling CDDB support

Yup, Gtkcdlabel is now broken for the same reason (missing dependencies).

The Debian developers *prefer* /usr/bin/python and *advise* against /usr/bin/env

  http://www.debian.org/doc/packaging-manuals/python-policy/ch-python.html#s-interpreter_loc

Perhaps I should lobby them for stronger terms.

please try again with the last version that uses python3

Yup, works great! Thanks!
