我对 Linux 还很陌生，但我用的是笔记本电脑，电池电量计会非常有用。每当我尝试
sudo apt-get install indicator-power
它给了我：

@Braiam 当我运行第一个命令来更正存储库时，它返回了以下内容：
Can't rename /etc/apt/sources.list.d/iaz-battery-status-quantal.list /etc/apt /sources.list.disable.d/iaz-battery-status-quantal.list.disable: No such file or directory
Can't rename /etc/apt/sources.list.d/ubuntu-wine-ppa-quantal.list /etc/apt/sources.list.disable.d/ubuntu-wine-ppa-quantal.list.disable: No such file or directory
Can't rename /etc/apt/sources.list.d/webupd8team-java-raring.list /etc/apt/sources.list.disable.d/webupd8team-java-raring.list.disable: No such file or directory
@Braiam，现在当我用那行运行它时，在我输入的每一行之后，除了这些之外，其他一切似乎都已经起作用之后，都会出现这样的响应：
N: Ignoring file 'ubuntu-wine-ppa-quantal.list.disable' in directory '/etc/apt/sources.list.d/' as it has an invalid filename extension
N: Ignoring file 'iaz-battery-status-quantal.list.disable' in directory '/etc/apt/sources.list.d/' as it has an invalid filename extension

答案1
问题是您有一些混合存储库。请执行以下操作：
sudo rename -n 's/\.list$/.list.disable/g' /etc/apt/sources.list.d/*.list
sudo apt-get update
sudo apt-get -f remove oracle-java7-installer
sudo apt-get autoremove
sudo apt-get -f install
sudo apt-get install indicator-power
第一行禁用任何非官方的存储库，第二行更新软件包列表，第四行尝试修复任何错误，最后安装软件包。

要安装 oracle java SDK 7，只需在软件中心搜索并安装即可。如果您将来需要下载任何其他软件，则应检查软件中心，它们有很多选择。
