Why did phpMyAdmin stop working after upgrading Ubuntu to 22.04?

Question

Just upgraded to Ubuntu 22.04 and now my phpadmin won't load. I get this following error

Parse error: syntax error, unexpected 'static' (T_STATIC) in /usr/share/php/Symfony/Component/DependencyInjection/ContainerBuilder.php on line 272

I opened up the file, and here is the specific code in that segment.

public function addResource(ResourceInterface $resource): static
{
    if (!$this->trackResources) {
        return $this;
    }

   if ($resource instanceof GlobResource && $this->inVendors($resource->getPrefix())) {
       return $this;
    }

    $this->resources[(string) $resource] = $resource;

   return $this;
}

Yesterday before the upgrade, everything was working fine. Does anybody have any suggestions?

What phpmyadmin and PHP itself versions do you have? – Noelianoell

I'm running 7.4 – Shellashellac

Are you sure this problem is related to Symfony itself? Did you write any code on your own for this problem? – Turin

Answer 1

I'm using php7.4.30 and my fix was upgrading phpMyAdmin.

Answer 2

Since version 8.0, PHP allows static as a return type for class methods. Apparently your PHP version was downgraded.

so I need to uninstall php 8 – Shellashellac

You have to use at least PHP 8.0, or downgrade phpMyAdmin – Ty

@GrzegorzPietrzak but he has Symfony error, not phpMyAdmin one, phpMyAdmin does not require PHP 8.0 yet, 7.4 for latest version, I believe – Noelianoell

Since version 5.0 PMA uses Symfony components, including DI Container. Looking at the Packagist - it should work with PHP 7.1.3+, but apparently something is not right. – Ty

solved it. Fully upgraded and added extra modules for php 8.1 – Shellashellac

Answer 3

Yes, it's a pain if you are running a PHP version prior to 8, such as 7.*. Download 5.2 here and install it.

https://www.phpmyadmin.net/downloads/

Completely purge your previous version and secure the directory where you install it (depends on your web server). That Symfony component ruined everything (line 272).

Answer 4

• upgrade php to 8.x
• switch php version in apache:

cd /etc/apache2/mods-enabled/
sudo rm php7.4.conf
sudo rm php7.4.load
sudo ln -s ../mods-available/php8.0.load php8.0.load
sudo ln -s ../mods-available/php8.0.conf php8.0.conf

at the end, restart apache:

sudo /etc/init.d/apache2 restart

Probably not necessary but just want to add that if you're on PHP 8.1 you need to change above commands to 8.1 – Malvie

Answer 5

You have to check your phpmyadmin version Coz in php 8.* version phpmyadmin 5.* version will be required.

Answer 6

Check the php version currently running php -v.

you need php 8.3. If you have it, enable the php mode 8.3 sudo a2enmod php8.3 and disable the current php mode say sudo a2dismod php7.4

then restart apache sudo systemctl restart apache2

navigate to /etc/apache2/mods-available to verify the changes. then test to access phpmyadmin
