尝试过直接提取到此处和用unzip命令解压压缩包，均失败。
可尝试用jar xvf filename.zip来进行解压
若提示jar:Command not found，则ubuntun下使用：sudo apt-get install -f jar,
运行结果如下图所示。

$ jar xvf 2.4.10.zip

*****2021.01.30更新
也有可能是因为没安装解压软件：）

1、压缩功能
安装 sudo apt-get install rar
卸载 sudo apt-get remove rar
2、解压功能
安装 sudo apt-get install unrar
卸载 sudo apt-get remove unrar
压缩解压缩.rar
解压：rar x FileName.rar
压缩：rar a FileName.rar DirName
