Ubuntu Environment

It is better to try Quectel SDK on Ubuntu 16.04 or 18.04, and not try the SDK on Ubuntu later than 22.04.

sudo apt-get install -y bison gcc make build-essential libc6-dev-i386 libncurses-dev wget coreutils diffstat  chrpath cpio gawk  sed     texi2html texinfo unzip flex bc     libssl-dev
sudo update-alternatives --install /usr/bin/python  python /usr/bin/python2  2700
