尝试在 Windows-subsystem-for-linux 上运行 java 我得到：
root@ST-NBXPS33:~# java
Command 'java' not found, but can be installed with:
apt install default-jre # version 2:1.17-75, or
apt install openjdk-17-jre-headless # version 17.0.12+7-1ubuntu2~24.04
apt install openjdk-21-jre-headless # version 21.0.4+7-1ubuntu2~24.04
然后 root@ST-NBXPS33:~# apt install default-jre 正在阅读包裹清单...完成 构建依赖树...完成 读取状态信息...完成
default-jre is already the newest version (2:1.21-75+exp1).
You might want to run 'apt --fix-broken install' to correct these.
The following packages have unmet dependencies:
default-jre : Depends: openjdk-21-jre but it is not going to be installed
default-jre-headless : Depends: openjdk-21-jre-headless but it is not going to be installed
openlogic-openjdk-17-hotspot : Depends: fonts-dejavu but it is not installable
E: Unmet dependencies. Try 'apt --fix-broken install' with no packages (or specify a solution).

然后
root@ST-NBXPS33:~# apt --fix-broken install
