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

N: Updating from such a repository can't be done securely, and is therefore disabled by default.

I've tried running sudo apt-get install ca-certificates but they already appear to be installed.

Any help will be greatly appreciated.

Retry with a fresh image from https://www.armbian.com/download/ ?

Another possible source of problem is that your system date and time is not set / set wrong.

Damm even I am having a similar kind of issue, I have searched all over the internet and even have posted on number of threads on different forum, no solution seems to work. I am really frustrated, can anyone of you here help me resolve this issue, I am very much tired now.
 

 

Can you share error messages please.

in my browser the https-certificate or "https://armbian.tnahosting.net/apt" is OK

 

Did you check time/date on your system and did you try (as suggested) "apt install ca-certificates" ?

 

If you got "armbian-config -> personal settigs -> mirrors" in your armbian-like distro then try to change the source/apt servers to EU and not automatic and try to reload the apt cache.

the July 1st error was legit, but the certificate was fixed soon afterwards.
