Raspberry PI 3B+, as always log into the console and run pihole -up
Pi-hole and web interface update regularly but when trying to update FTL from 5.8.1 to 5.9 this error message pops up
[✗] Update local cache of available packages
Error: Unable to update package cache. Please try "sudo apt-get update"
Unable to complete update, please contact Pi-hole Support
Upon trying to run sudo apt-get update this message is shown:
Reading package lists... Done
E: Repository 'http://raspbian.raspberrypi.org/raspbian buster InRelease' changed its 'Suite' value from 'stable' to 'oldstable'
N: This must be accepted explicitly before updates for this repository can be applied. See apt-secure(8) manpage for details.
Haven't gone beyond this point to avoid mistakes.
