libgcc1、libc6、およびlibstdc ++ 6を削除




Just this one made your system unusable:

Package: libc6 (2.15-0ubuntu10.5) [security]

Embedded GNU C Library: Shared libraries

Contains the standard libraries that are used by nearly all programs on the system. This package includes shared versions of the standard C library and the standard math library, as well as many others.

I would suggest to re-install without(!) formatting discs. It is the easiest and quickest method to get your system back up. In case you have files on that system you need to save: use the live dvd to mount your user partition and burn them to a dvd. Just as a precaution.
