Just install elasticsearch always failed in ubuntu 20

[daoxuans]

I have a virtual machine, 16GB memory and 16 vCpus, OS(ubuntu 20)
Just install elasticsearch always failed, i found that it is related to the security certificate setting and password changing.

When I ignore this error and start directly, I find that I cannot log in with my account password (elastic/mypasswd)
