Restart your router and modem.
If you are running a firewall or third-party anti-virus, disable them (better yet, uninstall them).
Try to upgrade.
Try booting into Safe Mode and try upgrade, again if it didn’t work.
If none of that works, take your MacBook Pro to a different network and try again.
whenever i try to update it it says requested version of macos is unavailable
