Java 更新问题

我在更新 Ubuntu 电脑时遇到问题。每次我启动更新命令时，终端都会返回以下内容：

 subprocess installed post-installation script returned error exit status 1
Errors were encountered while processing:

E: Sub-process /usr/bin/dpkg returned an error code (1)

我该怎么做才能解决这个问题？

答案1

确保签入/usr/lib/jvm/java-8-oracle/文件夹并删除残留的 Java 文件夹，该文件夹将以您计算机上的最新 Java 文件夹命名。将 替换{current-java-version_folder}为该文件夹的名称，然后运行以下命令：

sudo rm -r /usr/lib/jvm/java-8-oracle/{current-java-version_folder}

然后再次安装Java：

sudo apt-get install -f
sudo apt-get purge oracle-java8-installer
sudo apt-get install oracle-java8-installer

然后跟进：

sudo apt-get install oracle-java8-set-default
