I asked on StackOverflow but was redirected here .
I'm afraid I made a kind of a booboo.
While performing an apt-get upgrade (there were about 160+ packages in queue) I accidentally logged out, thus aborting the upgrade midway. Now I can't restart the upgrade.
apt-get upgrade says there are no packages to upgrade...
apt-get update gives errors:
W: Failed to fetch http://security.debian.org/dists/wheezy/updates/main/binary-armel/Packages Hash Sum mismatch
W: Failed to fetch http://security.debian.org/dists/wheezy/updates/contrib/binary-armel/Packages Hash Sum mismatch
W: Failed to fetch http://security.debian.org/dists/wheezy/updates/non-free/binary-armel/Packages Hash Sum mismatch
[several more of these... and ending in: ]
E: Some index files failed to download. They have been ignored, or old ones used instead.
E: Couldn't rebuild package cache
Full output is here on pastebin
I tried these without success:
apt-get -f install
Output:

dpkg --configure -a
No output
rm -vf /var/lib/apt/lists/*; rm -vf /var/lib/apt/lists/partial/*; apt-get update
Same errors as above.
dpkg-reconfigure -a
Eventually aborts after this:

dpkg-query: error: --status needs a valid package name but 'gcc-4.7-base' is not: ambiguous package name 'gcc-4.7-base' with more than one installed instance
Use --help for help about querying packages.
/usr/sbin/dpkg-reconfigure: gcc-4.7-base is not installed
I don't know how to find out what was installed and what was not.
Any tips how to recover from this are very welcome!
This probably should be moved to superuser or such, but since you already were re-directed...
First I would suggest to run such things in a screen session. That will keep the update going when you log out or the connection dies:
To de-tach the session press CTRL a then press d
To re-attach the session type:
It will be helpful to also paste the output of the things you listed which you tried without success.
Some suggestions:
I got my suggestions from: https://askubuntu.com/questions/41605/trouble-downloading-packages-list-due-to-a-hash-sum-mismatch-error/
Edit: judging from the info you added you may need to force remove gcc-4.7-base and then re-install it and repeat dpkg-reconfigure -a. If it then fails for another package repeat this process until it succeeds, then re-run apt-get (dist-)upgrade.
