我尝试安装openjdk-7-jre。它显示了如下错误
E: Package 'openjdk-7-jre' has no installation candidate
所以我尝试了
sudo add-apt-repository ppa:webupd8team/java
它运行良好。然后我通过命令更新
sudo apt-get update
它也运行良好。但是在命令之后
sudo apt-get install oracle-java7-installer
我收到错误
E: Sub-process /usr/bin/dpkg returned an error code (1)
我正在粘贴错误消息。它显示下载失败，并且未安装 Oracle JDK 7。错误在哪里？该怎么办？
