Roll in your backup.
No backups, or corrupt backups?
Load whatever the most current version might be.
Getting older installers is getting more difficult. Just using those same older versions is getting tougher, too.
Tried Option-⌘-R newest-version Recovery here, if your particular Mac supports that?
If Recovery of any sort is not working, then the paths involve another Mac, and either downloading and building a bootable USB installer on that other Mac and particularly with a Mac that is running the target version of macOS, or using Target Disk Mode and installing from another Mac, or swapping the internal storage around.
If this is a usual path that these discussions so often follows, your hardware is probably failing, and needs repair or replacement.

Try using wired network only, and set your default DNS server on your DHCP server (that’s probably your router) to 1.1.1.1, 8.8.8.8, or 9.9.9.9, and try again. Also try verifying your Recovery environment.
...though I’d suspect this whole adventure is being caused by a hardware problem. Folks running with these older OS X releases and encountering these sorts of errors far too often think “hey, maybe I should reinstall”, and when the eventual solution can be closer to “I should replace this very old hard disk with an SSD”, or “This Mac needs a repair or replacement”.
