Ubuntu 17.10 Java 8证书错误

我重新安装了Ubuntu 17.10，并在其中安装了oracle-java8-installer软件包（来自PPA）。

但是，当我尝试使用“ ionic cordova build android”编译一个离子项目时，会引发以下错误：

我已连接到互联网，并尝试：

$ sudo update-ca-certificates -f
$ sudo apt install --reinstall ca-certificates-java

...并重新安装npm，ionic，java和gradle，所有操作均未成功。

编辑：我也有在.bashrc中导出的ANDROID_HOME和JAVA_HOME，并安装了Android Studio。我试图在另一台机器上构建项目，并且工作正常。我无法尝试使用OpenJDK，因为它无法在Android Studio中正常工作。

尝试

sudo dpkg --purge --force-depends ca-certificates-java

其次是

sudo apt-get install ca-certificates-java

修复损坏的证书。
对我来说，这解决了它。
祝好运！
