Hi… I am not techie guy, and newbie with PHP dependency…  
But, I try to install composer on my hosting, via ssh  
so I follow step on this [How to install Mautic | Mautic](https://docs.mautic.org/en/setup/how-to-install-mautic/install-and-manage-mautic-with-composer:)

and this is result

1. install composer (success)
2. run this

```auto
composer create-project mautic/recommended-project:^4 some-dir --no-interaction

```

and succes  
3. run this

```auto
cd some-dir
composer require mautic/mautic-saelos-bundle:~2.0

```

and i get the problem on my ssh terminal.

```auto
[asokamai@sng100 some-dir]$ composer require mautic/mautic-saelos-bundle:~2.0

  Problem 1
    - Root composer.json requires mautic/mautic-saelos-bundle ~2.0 -> satisfiable by mautic/mautic-saelos-bundle[2.0, 2.1].
    - mautic/mautic-saelos-bundle[2.0, ..., 2.1] require tightenco/collect ^5.6 -> found tightenco/collect[v5.6.0, ..., v5.8.38] but the package is fixed to v8.83.2 (lock file version) by a partial update and that version does not match. Make sure you list it as an argument for the update command.

Use the option --with-all-dependencies (-W) to allow upgrades, downgrades and removals for packages currently locked to specific versions.

Installation failed, reverting ./composer.json and ./composer.lock to their original content.
[asokamai@sng100 some-dir]$ ^C
[asokamai@sng100 some-dir]$

```

How to fix it…?  
or what step can I do …?

thanks
