I installed Java 7 and later I got troubles with my system, I can't update anymore. The package system is broken

Check if you are using third party repositories. If so disable them, since they are a common source of problems. Furthermore run the following command in a Terminal:

1) sudo dpkg --check ==> no results, does not recognise command

2) sudo apt-get check Reading package lists... Done Building dependency tree
Reading state information... Done You might want to run 'apt-get -f install' to correct these. The following packages have unmet dependencies: libc6 : Depends: libgcc1 but it is not installed Depends: tzdata but it is not installed E: Unmet dependencies. Try using -f.

3)apt-cache policy debconf debconf: Installed: (none) Candidate: 1.5.42ubuntu1 Version table: 1.5.42ubuntu1 0 500 http://archive.ubuntu.com/ubuntu/ precise/main i386 Packages

4) apt-get install -f

The following packages have unmet dependencies:

    libc6: Depends: libc-bin (= 2.15-0ubuntu10.5) but 2.15-0ubuntu10.5 is installed
           Depends: libgcc1 but it is not installed
           Depends: tzdata but it is not installed

sudo apt-get install -f

Does a sudo apt-get install -f do anything? –  Ross Feb 28 at 14:52
    
added the apt-get install -f results –  user233269 Feb 28 at 14:55
    
Did you erase any packages before running that command? It looks like the package manager is missing quite a few crucial packages. –  Ross Feb 28 at 15:17
    
yes, I did, before installing java 7, I executed a terminal command to help me install serviio, but that was a command for Fedora and not ubuntu. –  user233269 Feb 28 at 15:19
    
Ah, okay. How exactly did you install Java? –  Ross Feb 28 at 15:20

If coreutils is not installed, your system is seriously hosed.

Does /bin/date exist and work? If yes, “just” your package database is corrupt. In this case, restore /var/lib/dpkg/status from a backup – e.g. /var/lib/dpkg/status-old or one of the files /var/backups/dpkg.status.* (remember to uncompress the *.gz files).
