How to Install PHP 8.2 on Ubuntu 26.04

To install PHP 8.2 on Ubuntu 26.04, Ubuntu’s repos only ship 8.5, so 8.2 needs packages.sury.org. ppa:ondrej/php is merging into Sury; on 26.04 that is the canonical source.

Step 1 : Update.

sudo apt update

Step 2 : Install the packages the repository setup needs.

sudo apt install lsb-release ca-certificates curl

Step 3 : Download the repository keyring.

sudo curl -sSLo /tmp/debsuryorg-archive-keyring.deb https://packages.sury.org/debsuryorg-archive-keyring.deb

Step 4 : Install the keyring.

sudo dpkg -i /tmp/debsuryorg-archive-keyring.deb

Step 5 : Add the PHP repository.

echo "deb [signed-by=/usr/share/keyrings/debsuryorg-archive-keyring.gpg] https://packages.sury.org/php/ $(lsb_release -sc) main" | sudo tee /etc/apt/sources.list.d/php.list

Step 6 : Update again.

sudo apt update

Step 7 : Install PHP 8.2, CLI, and PHP-FPM.

sudo apt install php8.2 php8.2-cli php8.2-fpm

Step 8 : Install common extensions. Common extensions: mysql, curl, gd / imagick, xml / xsl / soap, zip, mbstring, bcmath. gettext is in php8.2-common.

sudo apt install php8.2-mysql php8.2-curl php8.2-xsl php8.2-gd php8.2-common php8.2-xml php8.2-zip php8.2-soap php8.2-bcmath php8.2-mbstring php8.2-imagick

Step 9 : Point the php command at 8.2 (26.04 already defaults to 8.5 if that package is installed).

sudo update-alternatives --set php /usr/bin/php8.2

Step 10 : Check the version.

php -v

You have installed PHP 8.2 on Ubuntu 26.04.
