我通过下载 jdk-7u40-linux-x64.tar.gz 并按照以下方法手动安装了 Java Jdk此链接。当我检查它的版本时，一切正常：
user@mylaptop:~$ java -version
java version "1.7.0_40"
Java(TM) SE Runtime Environment (build 1.7.0_40-b43)
Java HotSpot(TM) 64-Bit Server VM (build 24.0-b56, mixed mode)
但是当我尝试使用此命令安装 pip 时：
sudo apt-get install python-pip
或者输入如下内容：
sudo apt-get -f install
我收到此错误：
user@mylaptop:~$ sudo apt-get install python-pip

你能告诉我如何解决这个问题吗？
答案1
您的系统中安装了 webupd8 oracle-java7-installer ，它正在尝试通过从 Oracle 网站下载来安装 Oracle Java。Oracle 网站限制了您的访问，这就是您收到此错误的原因。
如果您已经手动安装了 Java，则可以删除 oracle-java7-installer。
运行以下命令来修复它。
sudo apt-get purge oracle-java7-installer
sudo apt-get autoremove
sudo apt-get install -f
它应该可以解决 dpkg 错误。
