I’m getting this issue after upgrading my symfony version from 3.4 to 6.2. You can check attach screenshot.

I just change my "symfony/symfony": "3.4.x-dev" to "symfony/symfony": "6.2.x-dev" and update relevant package version and everything was going good but at the end I got this issue :

    2 options:

    • update versions 1 by 1
      3.4, 4.4, 5.4, 6.2

    • install a new 6.2 and copy-paste your 3.2 src in it, then redo all the configuration by hand.

    Swiftmailer-bundle is not supported beyond Symfony 5.0 – you will have to switch to symfony/mailer and refactor your code appropriately. Similarly, you can now either have symfony/symfony or symfony/config, but not both.

    You’ll also want to switch to Flex around Symfony4 and refactor your project structure.

    All in all, you probably want to paste your 3.2 into a new 6.2 project and update all of your controllers and services auto-wired dependency injection. It’s weeks worth of work.
