  1. Hey everyone...I've tried searching the problem I'm having and have tried different things...all so far to no avail. I'm relatively new to learning about pihole and decided to go out and buy the kit from ameriDroid (maybe should have built my own but decided to go this route to try and save myself some time). I received the kit today and started following the install instructions (I am attempting to install via SSH thru Putty). Once I reached the install command, I get an error stating: "Error: Unable to update package cache. Please try "apt-get update". I've tried the apt update/upgrade and I'm still getting the same error. The output from the apt-get update command is the following: root@rock64:/home/pihole# sudo apt update Hit:2 http://ports.ubuntu.com focal InRelease Hit:3 http://ports.ubuntu.com focal-security InRelease Ign:1 https://armbian.tnahosting.net/apt focal InRelease Hit:4 http://ports.ubuntu.com focal-updates InRelease Hit:6 http://ports.ubuntu.com focal-backports InRelease Err:5 https://armbian.tnahosting.net/apt focal Release Certificate verification failed: The certificate is NOT trusted.

Done W: http://apt.armbian.com/dists/focal/InRelease: No system certificates available. Try installing ca-certificates. W: http://apt.armbian.com/dists/focal/Release: No system certificates available. Try installing ca-certificates. E: The repository 'http://apt.armbian.com focal Release' does not have a Release file. N: Updating from such a repository can't be done securely, and is therefore disabled by default. N: See apt-secure(8) manpage for repository creation and user configuration details. I've tried running sudo apt-get install ca-certificates but they already appear to be installed. Any help will be greatly appreciated.
