[jorgen jorgensen (jgj-barskdata)]

There should exist a fix to the meld3 which causes the problem with the line:
"from xml.etree.ElementTree import fixtag"

I havent found the fix, but used the following workaround (in a terminal) :

sudo apt-get install python-setuptools
sudo apt-get install python-setuptools
sudo easy_install elementtree

[intel352 (intel352)]

Jorgen's workaround fixed this issue for myself as well. Installing supervisor under Natty

[Kristian Øllegaard (oellegaard)]

I can confirm that Jørgen's solution worked for me too, maybe the dependencies just needs to be updated?

It is also reported here: https://bugzilla.redhat.com/show_bug.cgi?id=652890

The proper fix is to update python-meld3 to 0.6.7.

And it is also described here:
http://vandahm.com/articles/how-fix-supervisor-ubuntu-1104/

[Jochem Oosterveen (jocmeh)]

You could also go for:

# apt-get install pip
# pip install meld3
# apt-get install supervisor

This will give you meld3 0.6.7 in /usr/local/lib/python2.7/dist-packages/meld3/, which sits in sys.path before /usr/lib/pymodules/python2.7/meld3/ (and that symlinks to /usr/share/pyshared/meld3/).

It's been a few months since this was reported but I just stumbled upon the same problem on Ubuntu 11.04. Won't this be fixed?

[Gediminas Paulauskas (menesis)]

This crash was fixed by uploading a patched python-meld3, available in Ubuntu 12.04 or later

python-meld3 (0.6.5-3.1) unstable; urgency=low

  * Non-maintainer upload.
  * Apply Ubuntu patch to make the package compatible with Python
    2.7. Thanks to Jessica McKellar. Closes: #644246.
    + Switch to 3.0 (quilt) source format to apply patch cleanly.
