无法删除JDK – / usr / sbin / alternatives：没有这样的文件或目录

当我尝试使用sudo apt-get remove jdk1.8.0-40删除Java时sudo apt-get remove jdk1.8.0-40我得到这个：

 Reading package lists... Done Building dependency tree Reading state information...

输出ls -1 /var/cache/apt/archives/*jdk* ：

输出sudo dpkg --purge --force-all jdk1.8.0-40 ：

在尝试编辑时，我得到了这个：

Answer 1

尝试在该文件夹中创建文件并执行uninstall命令：

 sudo mkdir -p /usr/java sudo touch /usr/java/aa sudo touch /usr/sbin/alternatives sudo apt-get remove jdk1.8.0-40 

编辑：

---

试试这个：echo“”| sudo tee /var/lib/dpkg/info/jdk1.8.0-40.postrm

Answer 2

 /usr/sbin/alternatives: No such file or directory 

在Debian，Ubuntu等Debian克隆中没有/usr/sbin/alternatives 。 相反，有/usr/bin/update-alternatives 。

我建议使用一个临时的符号链接来解决转换不良的RPM包：

 mkdir -p /usr/sbin ln -sT -- /usr/bin/update-alternatives /usr/sbin/alternatives
