在新鲜的Ubuntu 17.10安装上，我根据文档安装了Scala构建工具(SBT(：
echo "deb https://dl.bintray.com/sbt/debian /" | sudo tee -a /etc/apt/sources.list.d/sbt.list
sudo apt-key adv --keyserver hkp://keyserver.ubuntu.com:80 --recv 2EE0EA64E40A89B84B2DF73499E82A75642AC823
sudo apt-get update
sudo apt-get install sbt
运行SBT时，要么只是为了获取其版本，要么是为了构建项目，我会得到此错误：

这是我的Java版本：
$ java --version
openjdk 9-Ubuntu
OpenJDK Runtime Environment (build 9-Ubuntu+0-9b181-4)
OpenJDK 64-Bit Server VM (build 9-Ubuntu+0-9b181-4, mixed mode)
我不知道发生了什么。如何再次启动并再次运行？
在我的情况下，在Ubuntu 18.04 Bionic和SBT 1.1.6，强迫重新安装ca-certificates-java将问题解决为解决方案。
sudo dpkg --purge --force-depends ca-certificates-java
sudo apt install ca-certificates-java
请注意--force-depends选项不会损坏您的安装。
在我的情况下，我必须清除：
sudo apt purge openjdk-9-jdk openjdk-8-jdk java-common
(仅清除和重新安装JDK还不够，此后我仍然有一个java命令。只有清除java-common也会消失然后重新安装。(
之后，我再次重新安装了Java(我仅选择了OpenJDK-9(：
sudo apt install openjdk-9-jdk
这个触发：Running hooks in /etc/ca-certificates/update.d...并添加了许多证书文件。现在我的SBT建造很成功：
