Runtime Exception - Repository not found

With and old laravel 5.5 project i am having this problem.

A package I was using has been removed from github and when i try composer install I get:

  [RuntimeException]                                                                                          
  Failed to execute git clone --mirror 'https://***:***@github.com/dangeroustry/FattureCloud.git' '/home/mir  
  co/.cache/composer/vcs/https---github.com-dangeroustry-FattureCloud.git/'                                   
                                                                                                              
  Cloning into bare repository '/home/username/.cache/composer/vcs/https---github.com-dangeroustry-FattureCloud  
  .git'...                                                                                                    
  remote: Repository not found.                                                                               
  fatal: repository 'https://github.com/dangeroustry/FattureCloud.git/' not found

So I tried to remove this package with composer remove vendor/package but I can't remove it. When i run the command

composer remove vendor/kiboko/fatture-cloud-laravel/

I get this error

[Composer\Downloader\TransportException]                                                                                                
  The "https://api.github.com/repos/dangeroustry/FattureCloud/zipball/4c4133a965985c1b8c6e41bbfb47ec912a167681" file could not be downlo  
  aded (HTTP/2 404 ) 

How to solve this loop?
