**Your software** My Mautic version is: Upgrade from 4 to 5 My PHP version is: 8.0.30 My Database type and version is: MariaDB 10.5.24 **Your problem** My problem is: While upgrading, from the frontend, the process got stuck at ‘Move Package Contents’. Visiting our Mautic setup now throws a PHP 500 error These errors are showing in the log: AH01071: Got error ‘PHP message: PHP Fatal error: Uncaught TypeError: Symfony\Component\Dotenv\Dotenv::loadEnv(): Argument #2 ($varName) must be of type string, null given, called in [/var/www/vhosts/mailagent.nl/app.mailagent.nl/app/config/bootstrap.php](https://analyze.email:8443/smb/file-manager/code-editor?currentDir=%2Fapp.mailagent.nl%2Fvar%2Fwww%2Fvhosts%2Fmailagent.nl%2Fapp.mailagent.nl%2Fapp%2Fconfig&subscriptionId=138&file=bootstrap.php&redirect=%2Fsmb%2Flog-file%2Fbrowser%2Fid%2F160) on line 20 and defined in [/var/www/vhosts/mailagent.nl/app.mailagent.nl/vendor/symfony/dotenv/Dotenv.php](https://analyze.email:8443/smb/file-manager/code-editor?currentDir=%2Fapp.mailagent.nl%2Fvar%2Fwww%2Fvhosts%2Fmailagent.nl%2Fapp.mailagent.nl%2Fvendor%2Fsymfony%2Fdotenv&subscriptionId=138&file=Dotenv.php&redirect=%2Fsmb%2Flog-file%2Fbrowser%2Fid%2F160):82\nStack trace:\n#0 [/var/www/vhosts/mailagent.nl/app.mailagent.nl/app/config/bootstrap.php](https://analyze.email:8443/smb/file-manager/code-editor?currentDir=%2Fapp.mailagent.nl%2Fvar%2Fwww%2Fvhosts%2Fmailagent.nl%2Fapp.mailagent.nl%2Fapp%2Fconfig&subscriptionId=138&file=bootstrap.php&redirect=%2Fsmb%2Flog-file%2Fbrowser%2Fid%2F160)(20): Symfony\Component\Dotenv\Dotenv-\>loadEnv()\n#1 [/var/www/vhosts/mailagent.nl/app.mailagent.nl/index.php](https://analyze.email:8443/smb/file-manager/code-editor?currentDir=%2Fapp.mailagent.nl%2Fvar%2Fwww%2Fvhosts%2Fmailagent.nl%2Fapp.mailagent.nl&subscriptionId=138&file=index.php&redirect=%2Fsmb%2Flog-file%2Fbrowser%2Fid%2F160)(9): require(’…‘)\n#2 {main}\n thrown in [/var/www/vhosts/mailagent.nl/app.mailagent.nl/vendor/symfony/dotenv/Dotenv.php](https://analyze.email:8443/smb/file-manager/code-editor?currentDir=%2Fapp.mailagent.nl%2Fvar%2Fwww%2Fvhosts%2Fmailagent.nl%2Fapp.mailagent.nl%2Fvendor%2Fsymfony%2Fdotenv&subscriptionId=138&file=Dotenv.php&redirect=%2Fsmb%2Flog-file%2Fbrowser%2Fid%2F160) on line 82’ running the composer through command line is giving me the following errors: PHP Fatal error: Declaration of Symfony\Flex\Command\RemoveCommand::execute(Symfony\Component\Console\Input\InputInterface $input, Symfony\Component\Console\Output\OutputInterface $output) must be compatible with Composer\Command\RemoveCommand::execute(Symfony\Component\Console\Input\InputInterface $input, Symfony\Component\Console\Output\OutputInterface $output): int in /var/www/vhosts/mailagent.nl/app.mailagent.nl/vendor/symfony/flex/src/Command/RemoveCommand.php on line 36 Fatal error: Declaration of Symfony\Flex\Command\RemoveCommand::execute(Symfony\Component\Console\Input\InputInterface $input, Symfony\Component\Console\Output\OutputInterface $output) must be compatible with Composer\Command\RemoveCommand::execute(Symfony\Component\Console\Input\InputInterface $input, Symfony\Component\Console\Output\OutputInterface $output): int in /var/www/vhosts/mailagent.nl/app.mailagent.nl/vendor/symfony/flex/src/Command/RemoveCommand.php on line 36 Steps I have tried to fix the problem: - delete the files in /var/cache - read a lot of blogposts and tried almost all given solutions… ---

Could you please go back to your last working backup and try again? This time please use the console / command line interface. It will probably save a lot of time, compared to trying to fix a broken update. [https://docs.mautic.org/en/5.x/getting\_started/how\_to\_update\_mautic.html](https://docs.mautic.org/en/5.x/getting_started/how_to_update_mautic.html) You will find the how-to for composer-based and non-composer-based setups. (Please never ever use the frontend for updating.) ---

@dirk_s : thank you for your assistance. I’ve now restored all files and run the update through command line. After running the --finish command an error thrown (at point 2, updating database) pointing me to the logfile. In the logfile the following error is given: [2024-04-24T16:12:15.589656+00:00] console.CRITICAL: Error thrown while running command “doctrine:migrations:migrate --quiet --no-interaction”.

Is this something you can help me with?
