Dear sir or madam i've been working on installing Archlinux on a older laptop i was almost finish when i tried to download xorg the mirrors,it's really hard to say what the error was but when i try a few times it wouldn't download, so i try to see if i can remove the older downloads and get some new one but it wouldn't let me so i'm between a rock and a hard place what i need is to be able to download from root the mirrorlist so i can keep going could you help me thank you
