Installing Docker on Arch Linux - 404 error from url
Fixed it.
I needed:
sudo Pacman -Syy docker
which first updates the repos.Oops.
I was also facing the same issue. I resolved it using
sudo pacman -Syy docker
The file isn't there because you're trying to get it probably from an older version. So you need to refresh them.
-y downloads a fresh copy of the master package database from the server(s) defined in pacman.conf(5). This should typically be used each time you use --sysupgrade or -u. Passing two --refresh or -y flags will force a refresh of all package databases, even if they appear to be up-to-date.
