Bug Report

Describe the bug

After following instructions from official site, I was not able to install debian package. The problem is that $CODENAME variable in bashscript is determined in incorrect way, when user has /etc/os-release file.

To Reproduce

curl https://raw.githubusercontent.com/fluent/fluent-bit/master/install.sh | sh

Expected behavior

Package should be installed.
