Big Sur install error 702
My Big Sur installation gets to about "13 minutes remaining" before throwing an error. The installer log in Console shows the info at the bottom.
The error on "disk3s2" doesn't make sense to me. I'm installing onto "Macintosh HD", which is APFS and, as you can see in the bottom right, is disk1s5:
"Macintosh HD - Data" is disk1s1.
"Shared Services", an image loaded during the installation process, is disk2s2.
I have no other drives connected.
