Currently we can not use http only protocol to access all armbian packages .
There is a http => https redirection .
This redirection prevent the usage of squid-proxy to optimize bandwidth .
I understand in other side the usage of https , the need of privacy/trust .
Can you propose a http-only alternative ?
Multiple solutions are possible :
no redirection , but you can still promote https urls
a second url that will be provide a http only access to repository
because we can change the user-agent for apt via this parameter Acquire::http::User-Agent
a rule based on user-agent that prevent redirection
a rule based on user-agent that do the redirection , with a default configuration for armbian .
