I'm having the same problem; when I run sudo apt-get update I get the following:
Hit:1 http://archive.raspberrypi.org/debian buster InRelease
Get:2 http://raspbian.raspberrypi.org/raspbian buster InRelease [15.0 kB]
Reading package lists... Done
E: Repository 'http://raspbian.raspberrypi.org/raspbian buster InRelease' changed its 'Suite' value from 'stable' to 'ol
dstable'
N: This must be accepted explicitly before updates for this repository can be applied. See apt-secure(8) manpage for det
ails.
