When running the Live CD what does the command 'apt-cache policy python-apt' return? Thanks in advance.

[Brian Murray (brian-murray)]

Ah, actually it is included in dependencies.txt:

python-apt 0.8.3ubuntu7.1
python-apt-common 0.8.3ubuntu7.1

You'll want a new version of the Precise (12.04) daily build which includes version 0.8.3ubuntu7.2.

[Brian Murray (brian-murray)]

python-apt (0.8.3ubuntu7.2) precise; urgency=medium

  * Cherry-pick fixes from 0.8.8ubuntu1 to close apt.Cache and free
    file-descriptors. (LP: #1051935).
  * Update list of mirrors from launchpad, using pre-build.sh hook.
