Bug Description

Binary package hint: file

I'm running Ubuntu 10.04 LTS.

I installed python-magic with: sudo apt-get install python-magic (the file that gets installed is python-magic_5.03-5ubuntu1_i386.deb)

However, when I start Python (version 2.6.5) and I "import magic" and I then do "dir(magic)", it seems as though the module does not contain all the definitions that I can see on python-magic's github repo (i.e. the Ubuntu package seems outdated):


What's up? Am I doing something wrong?


I have the same problem on natty with python-magic 5.04-5ubuntu2 and python 2.7.1-0ubuntu5.

The magic module does not contain the Magic class, rendering the module useless.

On the off chance someone doesn't know, a workaround is:
sudo apt-get remove python-magic
sudo apt-get install python-pip
sudo pip install python-magic

Changed in file (Ubuntu):
status: New → Confirmed

Seems to be broken on Ubuntu 12.04 and 13.10 and possibly all versions between that.

Not sure what is up with this, is this actually a different library than "pip install python-magic" will install???

>>> import magic
>>> magic.from_buffer
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
AttributeError: 'module' object has no attribute 'from_buffer'

Also I noticed the version is completely wrong it's like version 5.04 when python-magic on pip is 0.4.6, what is up with that?

Unfortunately I need this package desperately, so I am going to have to package it up myself and bump up the version of the package, even though it's wrong, so that it will overinstall the broken python-magic package.

I had quick a look inisde the Ubuntu 12.04 package for python-magic and it definitely appears to be the same library as on pip, it's just a very old version which doesn't appear to be very useful at all, also it's not versioned correctly, it has the same version as libmagic (5.09-2) but it should really by 0.4.6 if the latest from pip was to be packaged.
