get-docker.sh: curl: (56) OpenSSL SSL_read: error:0A000126:SSL routines::unexpected eof while reading, errno 0

Hello,

I run the get-docker.sh script quite often and occasionally hit this issue:

Do you have any recommendations?

Thanks.

Start with get-docker.sh and the curl command that downloads https://download.docker.com/linux/ubuntu/gpg. Investigate the reported intermittent OpenSSL unexpected EOF during installation and determine a reproducible failure case and an appropriate way to consider the installation complete.
