PKDownloadError error 8 Clean install

[Surrq31]

I’m getting “PKDownloadError error 8” while doing a clean install at 13 minutes remaining.
After updating to Big Sur I use the recovery cmd+r then remove the data partition and initialize the hdd. After doing this reinstall Big Sur. Always getting this error when it’s at 13 minutes remaining. MacBook Pro 15 2019

Same here, there is something wrong with Apple Big Sur Server because with Catalina it works nice but they don’t want to admit it. I solved using this work around to install Big Sur:

1. Activate a hotspot with your iPhone or Smartphone
2. Press CMD + R to start your Mac in recovery mode
3. Connect your Macbook/iMac/Mac mini to hotspot
4. If possible use disk Utility to initialize your disk
5. Launch Big Sur Installation and start download
6. When the download start or during the download -> disconnect your Mac from hotspot and connect it to your wifi or use a Lan adapter. You must be very fast.
7. The download will be completed with the new connection

Hope this helps you.

I resolved as well tethering with my iPhone. You could try to change the DNS on your router if tethering is not an option for you.
