I am trying to install or upgrade whatever suits best from PHP 7.0 to 7.2. I'm facing below while running sudo apt-get update
.
Would appreciate if someone could let me know how to proceed with this.
Reading package lists... Done
E: The repository '//https://packages.sury.org/php stretch 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.
