无法在 ubuntu 20 上安装 php 7.3

Question

hi i want to install php 7.3 on ubuntu 20 for my nginx web server, when i try to install the 7.4 version every thing is fine but for 7.3 i get this error

E: Unable to locate package php7.3

then i run the commands below:

sudo apt-get install software-properties-common
sudo add-apt-repository ppa:ondrej/php
sudo apt-get update
sudo apt-get install -y php7.3

but again it shows that it cant locate the package. does ubuntu 20 supports php 7.3 or below and if yes what can be wrong with mine??

Answer 1

Solution

Add Ondrej PPA repository to your system.

sudo apt install software-properties-common
sudo add-apt-repository ppa:ondrej/php
sudo apt update

Install php7.3 and check it's installed.

sudo apt install -y php7.3
php -v

This also works for php 7.4, php7.2 and php5.6. Just change the relevant digits.
