如何修复apt-get命令？

Question

当我尝试使用 安装新软件包时apt-get install，它不起作用。apt-get update也不起作用。

你知道如何重新安装它才能再次工作吗？

sudo dpkg --configure -a 的输出：

dpkg: dependency problems prevent configuration of tvbrowser:
 tvbrowser depends on sun-java6-jre | sun-java5-jre; however:
  Package sun-java6-jre is not installed.
  Package sun-java5-jre is not installed.
dpkg: error processing tvbrowser (--configure):
 dependency problems - leaving unconfigured
Errors were encountered while processing:
 tvbrowser

从输出命令和apt-get安装太阳的Java6的JRE

Reading package lists... Done
Building dependency tree       
Reading state information... Done
Package sun-java6-jre is not available, but is referred to by another package.
This may mean that the package is missing, has been obsoleted, or
is only available from another source
E: Package sun-java6-jre has no installation candidate

这个 pastebin的输出为find /etc/apt/ -name '*.list' -ls -exec cat {} \; > repositories.txt.

我从您的错误输出中注意到的是：

dpkg: dependency problems prevent configuration of tvbrowser:

尝试：

希望这会有所帮助，如果有帮助的话。
