So how would I be able to fix it? My router is allowing the url requests, and not dropping them.

I have an orange pi zero that I'm going to use as a pi hole. When installing pi hole, I received a "Error: Unable to update package cache. Please try "sudo apt update"." I did just that and received another error stating Err:1 https://ports.ubuntu.com focal InRelease Could not connect to ports.ubuntu.com:443 (2620:2d:4000:1::19). - connect (111: Connection refused) Could not connect to ports.ubuntu.com:443 (185.125.190.39). - connect (111: Connection refused) Could not connect to ports.ubuntu.com:443 (2620:2d:4000:1::16). - connect (111: Connection refused) Could not connect to ports.ubuntu.com:443 (185.125.190.36). - connect (111: Connection refused) Err:2 https://ports.ubuntu.com focal-security InRelease Unable to connect to ports.ubuntu.com:https: Err:3 https://ports.ubuntu.com focal-updates InRelease Unable to connect to ports.ubuntu.com:https: Err:4 https://ports.ubuntu.com focal-backports InRelease Unable to connect to ports.ubuntu.com:https: Ign:5 https://apt.armbian.com focal InRelease Err:6 https://apt.armbian.com focal Release Redirection from https to 'http://armbian.chi.auroradev.org/apt/dists/focal/Release' is forbidden [IP: 2605:7900:20::5 443] Reading package lists... Done E: The repository 'https://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 tried changing the mirror url in /etc/apt/sources.list.d/armbian.list as @Werner suggested, but I still get the same error even when using the mirror. This is basically what's in the armbian.list deb http://armbian.tnahosting.net/dl/ focal main focal-utils focal-desktop Any clues as to what's going on??
