[FIXED] Laravel Nova installation via composer fails on production server

Issue

I have added Laravel Nova to our application and purchased a license. On the local server everything works perfectly. However, when I try to deploy the updated application to our linux server and run composer update it says:

Failed to download laravel/nova from dist: /var/www/{myPath} does not exist and could not be created.
    Now trying to download from source

Syncing laravel/nova (3.29.0) into cache

Cloning failed using an ssh key for authentication, enter your GitHub credentials to access private repos
Head to https://github.com/settings/tokens/new It will be stored in "/var/www/{myPath}"

So I created a GitHub Token and added the Laravel Nova credentials to the auth.json file on the server too. Everything should be correct and it is working on the local copy as I said before. However, I am getting the following errors:

and the repository exists.      

How could I solve this problem?

Solution

Deleting the /vendor directory and the composer.lock file and running composer install --optimize-autoloader --no-devsolved the problem.
