(2) Use aptitude to install lib32z1. Using sudo apt-get install lib32z1, I found that it could not be installed. The reason is that ubuntu is too new. Many libraries in it are new versions, but lib32z1 based on this new version is not available yet, so it cannot be installed. The solution is to use the aptitude tool to install.
Note that aptitude is not necessarily successful.
First, ensure that the virtual machine is connected to the Internet, and you can try the NYY option. Otherwise, sometimes you have not downloaded a thing for a long time. Try the first option N and then choose Y to succeed.
(3) Test execution arm-xxx-gcc -v, prompting stdc++ not found error:

(4) Use aptitude to install lib32stdc++6-4.8-dbg
sudo aptitude install lib32stdc++6-4.8-dbg
to test arm-xxx again -gcc -v, it can finally run.
