PHPMyAdmin not working as intended at remote server. Error 500, $respond not found-CodePudding

I am just starting my journey with servers so I bought one VPN. I installed there ubuntu 18, apache 2.4, php8, webmin, mysql etc. I have two sites based on symfony 5 hosted here without any problems. I installed PHPmyAdmin using Ubuntu PPA: https://github.com/phpmyadmin/phpmyadmin/wiki/DebianUbuntu#ubuntu-ppa

When I go to mysite.com/phpmyadmin everything is fine. I log in with credentials and I am logged in. It reads databases properly and renders all UI as it should, but then it throws error 500 Screenshot of PHPmyadmin

And it throws error in apache logs:

I have no idea what is wrong.

CodePudding user response：

It is a bug / incompatibility in one of phpmyadmin dependencies - symfony dependency injection componenet and ubuntu package.

issue for ubuntu:
https://bugs.launchpad.net/ubuntu/ source/symfony/ bug/1932552

symfony issue:
https://github.com/symfony/symfony/commit/8e34978e4e2c4bf7dac97e44e904368c4cfb54f8

phpmyadmin isseue stating they cannot do anything:https://github.com/phpmyadmin/phpmyadmin/issues/16968#issuecomment-864088274

Tldr: Try udpating your dependecies, possiblity changing repositories in ubnutu or wait until fix is distributed.

apt-get update && apt-get upgrade -y

You can also downgrade your phpmyadmin version (not sure if it will help as it can be tied to php8.0 version)

Thanks to @nakashu I found solution.

According to symfony issue he linked: https://github.com/symfony/symfony/commit/8e34978e4e2c4bf7dac97e44e904368c4cfb54f8

I know it is only temporal solution but I replaced code in /usr/share/php/Symfony/Component/DependencyInjection/ContainerBuilder.php:1140

I changed:

$service = null === $r->getConstructor() ? $r->newInstance() : $r->newInstanceArgs($arguments);

to:

$service = null === $r->getConstructor() ? $r->newInstance() : $r->newInstanceArgs(array_values($arguments));

Now phpMyAdmin is working.
