我无法用 apt-get 做任何事情，因为有一个愚蠢的软件包阻止它工作。以下是发生的情况：
$ sudo apt-get upgrade
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:
gimp-help-sv : Depends: gimp-help-common (= 1:2.8-0precise8~ppa) but 1:2.8-0precise16~ppa is installed
E: Unmet dependencies. Try using -f.
好的，那我就跑了apt-get -f install。
$ sudo apt-get -f install
Reading package lists... Done
Building dependency tree

Correcting dependencies... Done
The following package was automatically installed and is no longer required:
icedtea-netx-common
Use 'apt-get autoremove' to remove them.
The following extra packages will be installed:
gimp-help-sv
The following packages will be upgraded:
gimp-help-sv

Do you want to continue [Y/n]?

好的。但是不可能是我没有空间了吧？
$ df -H

无论我尝试做什么，都会发生这种情况。我该如何摆脱这些愚蠢的消息？
