我在本地有.deb文件，我使用的是ubuntu14.04 64位。有没有人可以在这方面提供帮助，提前谢谢。

问题似乎出在Jenkins身上:你安装的版本与java 1.7.0_131不兼容。每次使用apt-get安装另一个包时，它都会报告jenkins安装被破坏。

我假设您运行的是像Ubuntu 14.04这样的linux发行版。如果是这种情况，您应该能够通过执行以下操作来解决此问题：

sudo add-apt-repository ppa:openjdk-r/ppa
sudo apt-get update
sudo apt-get install openjdk-8-jdk

然后，您需要使用以下命令更改java的默认版本：

update-java-alternatives --list
sudo update-java-alternatives --set /path/to/java-8

例如：

sudo update-java-alternatives --set /usr/lib/jvm/java-1.8.0-openjdk-amd64

现在您可以运行：

sudo apt-get upgrade

现在jenkins应该可以正确升级/安装了。在此之后，apt应该会再次工作，没有错误/抱怨。
