EOF Error while running apt-get upgrade

[pranavashok]

I'm running Ubuntu Oneiric (32bit) and I first got this error when running 'apt-get upgrade'. Now I keep getting it whenever I'm trying to run apt and also while opening other programs (gedit, for example).

Traceback (most recent call last):
  File "/usr/lib/python2.7/site.py", line 62, in <module>
    import os
  File "/usr/lib/python2.7/os.py", line 49, in <module>
    import posixpath as path
EOFError: EOF read where object expected
dpkg: error while cleaning up:
 subprocess installed post-installation script returned error exit status 1

The problematic packages were

Errors were encountered while processing:
 /var/cache/apt/archives/python-httplib2_0.7.1-1ubuntu1_all.deb
 /var/cache/apt/archives/python-pkg-resources_0.6.16-1_all.deb
 /var/cache/apt/archives/python-libxml2_2.7.8.dfsg-4ubuntu0.2_i386.deb
 /var/cache/apt/archives/ubuntuone-couch_0.3.0-0ubuntu2_all.deb

I tried removing those packages with synaptic and the EOF error repeated.

The complete log of running the 'apt-get -f install' command is here

Hello pranavashok.

Have you tried typing in:

apt-get update

to update apt's package list? Then try:

apt-get upgrade

Yes, those were the first things I tried.

Another thing I did was download Python 2.7 source and copy the site.py and the os.py files into my /usr/lib/python2.7/ directory. Doesn't help.

Looks like this is a bug. I've been googling all over the place, and it most people with the problem don't seem to have a solution.
How difficult would an OS reinstall be...? Painful for a seemingly small thing, but I don't know what else you could do to fix it.
