Did you run the commands for composer install and setup upgrade?

It seems you deleted our issue template which makes it harder to help you.

Which commands do I need to type in console?

But this could not be reproduced and there is no fix... What can I do now? Is it possible to "reinstall" those composer thinks without dropping a database or losing installed templates?

Hello?

Was vendor and composer.lock really moved / renamed / deleted?

Is the auth for magento.com still intact/working?

I guess an install step is missing.

[allumanatu]

Which auth for magento.com? Sorry, I am a total beginner. What do I have to change or type?
Which install step is missing? The installation had beed successfull, 1 month ago.
Sind Sie nicht auch Deutscher Herr Ruf? Danke übrigens für Ihre Hilfe! :-)

[allumanatu]

I would be happy to get an anwser, Magento community? Where are you? @magento

[DanielRuf]

Sind Sie nicht auch Deutscher Herr Ruf? Danke übrigens für Ihre Hilfe! :-)

GitHub is an english platform and support is in English.

Magento stores the auth info in auth.json in the global composer directory.

Magento-CE-2.2.3-2018-02-23-10-26-06.tar.gz

Was this a normal install without the composer steps?

[DanielRuf]

Please try

composer require magento/product-community-edition 2.2 --no-update
composer update
php -f bin/magento setup:upgrade

I guess some parts are out of sync, eg symfony/yaml as it conflicts with symfony/console.

[DanielRuf]

Also see https://github.com/symfony/yaml/blob/b3d0c9c11be3831b84825967dc6b52b5a7b84e04/composer.json#L25

[AshwinParmar]

Can I install magento 2 without UI interaction. e.g. using php bin/magento ??

[DanielRuf]

Sure, there is a setup:install command afaik.
