Please follow the below template, it will help us to help you!

Hi Guys, I've got a R pi 4 running RasbianOS and i've been running a Pihole on it for a couple of years now. I always ssh in and use commands "pihole -v", "pihole -up" to update and it has worked up until today. Now I'm getting an error and not sure what to do.

Expected Behaviour:

Should update normally.

Actual Behaviour:

Getting error: Error: Unable to update package cache. Please try "sudo apt-get update"
Unable to complete update, please contact Pi-hole Support. Upon running "sudo apt-get update" it says:
pi@raspberrypi:~ $ sudo apt-get update
Get:1 http://raspbian.raspberrypi.org/raspbian buster InRelease [15.0 kB]
Hit:2 http://archive.raspberrypi.org/debian buster InRelease
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.

Debug Token: none

Please help

That's an OS level issue, rather than Pi-hole.

Please consider searching the forums before opening a new issue - this has been asked and answered many times, e.g. see Can't update to FTL 5.9 Final: "Error: Unable to update package cache." - #2 by Bucking_Horn or Update fails on local cache update - #7 by Bucking_Horn.
