Easy Installation Issue . Failed to download key (Mariadb)

Bench Installation error using easy install in fresh Ubuntu desktop 16.04

sudo python install.py --production --user <user_name>

I tried installing it on 18.04 as well. I got the same issue.

Please suggest if I am missing something.

Just do it again. It is an internet download issue.

 sudo python install.py --production --user <user_name>  --mysql-root-password <mysql_password> --mariadb-version 10.3 --admin-password <admin_password>

You might like to do the one above so you don’t have to wait for the mysql and admin password prompts and also set the mariadb version to 10.3 instead of 10.2

Thank you for your response.

It was the issue with the download. keyserver.ubuntu.com was not responding to the request. I fixed by searching the key from keyserer.ubuntu.com, copied in the text file and then export the key.
