The Boilerplate response from Apple would be found in this link below

If an error occurred while updating or installing macOS - Apple Support

Another, more involved response below

There are factors:

Some which are beyond your control and those which are totally under your control

Like poor Wifi connection

Slow wifi connection

Too many other people downloading at the same time and Apple Servers are overloaded

Software on the computer interfering with the download process including AntiVirus Software

Notation: Disabling the AV Software may or may not solve the issue.

Removal of the AV Software may increase the chances of the download to perform as expected.

Running behind a Commercial VPN which may increase Packet losses or corruption of the download

Turn off any Third Party Two Way Firewall and try again

If via wifi & too many Other devices using the wifi at the same time reducing the Bandwidth to your computer.

Best Results are via Ethernet Cable to Router

Restart in Safe Mode. This will perform a Disk Repair, clear cache files and only load Apple Software, extensions and fonts. The boot up will be slow and can take some time - Normal

Try Again using the Software Update Applet in System Preferences / Setting

Worst case - Restart in Recovery Mode and choose Reinstall macOS.

This in theory will pull the latest version of macOS this computer qualifies to run
