How to solve :
I know you bored from this bug, So we are here to help you! Take a deep breath and look at the explanation of your problem. We have many solutions to this problem, But we recommend you to use the first method because it is tested & true method that will 100% work for you.
Method 1
The problem is not with Debian. It’s with https://packages.sury.org/php. That’s a 3rd party repository.
First, ensure that your buster installation (without the PHP stuff) is good and will handle certificates:
sudo mv /etc/apt/sources.list.d/php.list{,.bak}
sudo apt update
sudo apt install apt-transport-https ca-certificates curl
Next, if (and only if) you trust the source, then restore php.list and get the latest signature:
sudo mv /etc/apt/source.list.d/php.list{.bak,}
sudo wget -O /etc/apt/trusted.gpg.d/php.gpg https://packages.sury.org/php/apt.gpg
sudo apt update
Edit: It sounds like you’ve lost your main Debian archive source. re-create it with:
echo "deb http://ftp.debian.org/debian/ buster main" | sudo tee -a /etc/apt/sources.list
then try again
Note: Use and implement method 1 because this method fully tested our system.
Thank you 🙂
