我一直在 debian jessie 中安装 java 8，如下所示:
echo "deb http://ppa.launchpad.net/webupd8team/java/ubuntu trusty main" > /etc/apt/sources.list.d/webupd8team-java.list
echo "deb-src http://ppa.launchpad.net/webupd8team/java/ubuntu trusty main" >> /etc/apt/sources.list.d/webupd8team-java.list
apt-key adv --keyserver keyserver.ubuntu.com --recv-keys EEA14886
apt-get update && apt-get install oracle-java8-installer -y
但突然之间，这不再有效了。
E: Unable to find the oracle8-java-installer package
我在下面又尝试了这一步，但我得到了同样的错误:
sudo add-apt-repository ppa:webupd8team/java
sudo apt-get update
sudo apt-get install oracle-java8-installer
最佳答案
下载(需要oracle账号)
https://www.oracle.com/technetwork/java/javaee/downloads/jdk8-downloads-2133151.html
jdk-8u211-linux-x64.tar.gz
作为根
cp jdk-8u211-linux-x64.tar.gz /usr/lib/jvm/
cd /usr/lib/jvm/
tar zxvf jdk-8u211-linux-x64.tar.gz
设置为默认运行:
update-alternatives --install /usr/bin/java java /usr/lib/jvm/jdk1.8.0_211/bin/java 4
update-alternatives --install /usr/bin/javac javac /usr/lib/jvm/jdk1.8.0_211/bin/javac 4
update-alternatives --config java
然后选择选项4 (因为之前运行了 update-alternatives --install/usr/bin/java java/usr/lib/jvm/jdk1.8.0_211/bin/java 4)
