Noob issue : "failed to retrieve some files"

[dhruv8sh-kdk]

So i keep hitting this error and I wonder if I'm doing something wrong.

fn main() {
    let root = "/home/user";
    let dbpath = "/home/user/.local/lib/pacman";
    let mut alpm = match alpm::Alpm::new(root, dbpath) {
        Ok(alpm) => alpm,
        Err(err) => {
            eprintln!("Failed to initialize ALPM: {}", err);
            return;
        }
    };
    let core = alpm
        .register_syncdb_mut("kde-unstable", SigLevel::USE_DEFAULT)
        .unwrap();

    core.add_server("http://mirror.4v1.in/archlinux/core/os/x86_x64").unwrap();
    // Added more servers here
    
    core.set_usage(Usage::SYNC | Usage::SEARCH).unwrap();
    match alpm.syncdbs_mut().update(true) {
        Ok(updated) => {
            if updated {
                println!("Database was updated." )
            } else {
                println!("Database is up to date.");
            }
        }
        Err(e) => {
            eprintln!("Failed to update database. {}", e);
        }
    }
}

If you add a logging callback you can see the mirror times out

This mirror is working with pacman just fine. I have also tested with more worldwide mirrors and local mirrors which are working just fine with pacman too. Might I add, I have also tested with core and extra repos as well.

I think there must be some other underlying issue. Could you please provide me with the code for the callback you are using.
