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 .
