Comment 6 for bug 1235166

Edit:
don't remove all packages containing the words linux, generic and raring !!!
basically just remove the packages linux-image-generic-lts-raring and linux-image-3.8.0-31-generic and another package witch is similar to these two (have forgotten the exact name).

Update:
After I deleted 3 packages from the dpkg's status file I was able to update again. I reinstalled dpkg, then I installed synaptic and checked all the ticks in "Other Sources" in the repositories. Then I changed the repositories server to server for Germany "de.archive.ubuntu.com" and reloaded package information. After rebooting I opened update manager and it asked me again to make the same update I did before the bug occured. The Update ended successfuly this time.
