Noob issue : "failed to retrieve some files"

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); } } } ```
