Ubuntu2022的才默认GLIBC_2.35，2020默认是GLIBC_2.31，版本太低了，我们要升级：

分析以上报错，发现是：Ubuntu2022的才默认GLIBC_2.35，2020默认是GLIBC_2.31，版本太低了，我们要升级：
在/etc/apt/sources.list文件末尾增加：
deb http://th.archive.ubuntu.com/ubuntu jammy main
更新源
apt update
安装libc6
sudo apt install libc6
弹出覆盖提示：选择yes
查看版本已经升级到2.35
ldd --version
真实服了，不给我更新到最新版。
