So I've been trying to upgrade Ubuntu 11.10 64-bit few days back and received an error:

dpkg: ../../src/archives.c:978: tarobject: Assertion `r == stab.st_size' failed.

So I followed this Ubuntu Forums post and this one.

Removed ubuntu-docs from info folder and status file.

Now whenever I try to install/remove/upgrade any package I receive an error:

Traceback (most recent call last):
File "/usr/lib/python2.7/dist-packages/aptdaemon/", line 968, in simulate
trans.unauthenticated = self._simulate_helper(trans)
File "/usr/lib/python2.7/dist-packages/aptdaemon/", line 1092, in _simulate_helper
return depends, self._cache.required_download,
File "/usr/lib/python2.7/dist-packages/apt/", line 235, in required_download
pm.get_archives(fetcher, self._list, self._records)
SystemError: E:I wasn't able to locate a file for the ubuntu-docs package. This might mean you need to manually fix this package.

When I try to install ubuntu-docs from command line, I get this output:

...which looks about the same as when I started with problem, so I looked in info -- there is no package ubuntu-docs but there is entry in status so I deleted it and tried again, but as soon as I do sudo dpkg --configure -a the entry for ubuntu-docs reappears.

Any thoughts?

Edit (not as a comment to save formatting):

This thread says I need to run sudo apt-get update after removing corresponding lines from status. So I ran sudo apt-get clean followed by sudo apt-get update. But I got a message saying:

E: dpkg was interrupted, you must manually run 'sudo dpkg --configure -a' to correct the problem.

After running sudo dpkg --configure -a, status file contains following lines:

Package: ubuntu-docs
Status: install reinstreq half-installed
Priority: optional
Section: doc
Version: 11.10.4

Not sure if it helps.

Here is what worked for me:

sudo dpkg --force-all -r ubuntu-docs

I'll report if anything goes wrong about it again.
BTW solution was posted at How to get dpkg working again?

Ohh yea word of advice: Now I need to use Synaptic to update system everytime -- cause ubuntu-docs is in every update and I need to untick it :-/. Guess I'll start other question to ask how to remove particular package from every subsequent update.
