最近我也遇到一个类似问题，同一个工具在Ubuntu16.04里面运行是好的，但是Ubuntu18.04运行就出错了。
我用file也看了是32bit的应用程序，但一直没想到Ubuntu18.04竟然默认去掉了32bit的library。
用uname命令打印系统信息，发现系统是64位系统
$ uname -a Linux latitude-e5440 5.3.0-40-generic #32~18.04.1-Ubuntu SMP Mon Feb 3 14:05:59 UTC 2020 x86_64 x86_64 x86_64 GNU/Linux
安装ia32-libs，提示找不到了，候选lib32ncurses5或lib32z1，我用了lib32z1.
sudo apt-get install ia32-libs Building dependency tree Reading state information... Done Package ia32-libs is not available, but is referred to by another package. This may mean that the package is missing, has been obsoleted, or is only available from another source However the following packages replace it: lib32ncurses5 lib32z1 E: Package ‘ia32-libs‘ has no installation candidate $ sudo apt-get install lib32z1
之前有部分应用不能运行估计也是这个原因。
不知道这个方法是不是可以适合WSL
Ubuntu18.04可执行文件运行提示No such file or directory
