解决方案：

sudo apt remove cmake #删除旧版本的cmake

sudo apt-get install build-essential libssl-dev

wget https://github.com/Kitware/CMake/releases/download/v3.20.0/cmake-3.20.0.tar.gz


tar -zxvf cmake-3.20.0.tar.gz
cd cmake-3.20.0
./bootstrap
make
sudo make install

cmake --version 

BUG2：bash: /usr/bin/cmake: No such file or directory
在安装完cmake之后，如果出现以下错误

则找到安装的cmake文件，进入cmake-X/bin的目录下寻找cmake，放到/user/bin即可

cp /home/user/Desktop/envirment/cmakeDownload/cmake-3.20.0/bin/cmake /usr/bin/
