HestiaCP 1.10.2 - File Manager "Unknown error" - Symfony MimeTypes missing

Hello,

I am running HestiaCP 1.10.2 on Ubuntu 24.04.

The Hestia File Manager opens normally and I can browse directories. However, when I try to open/edit a file, the editor opens empty and displays:

“Unknown error”

The FileGator log shows this fatal error:

Uncaught Error: Class “Symfony\Component\Mime\MimeTypes” not found in /usr/local/hestia/web/fm/backend/Controllers/DownloadController.php:78

I checked the installation and this directory is missing:

/usr/local/hestia/web/fm/vendor/symfony/mime

Hestia version:

1.10.2-1+ubuntu24.04

The file /usr/local/hestia/web/fm/backend/Controllers/DownloadController.php uses Symfony\Component\Mime\MimeTypes, but the corresponding Symfony Mime dependency is not present in the active vendor directory.

The FileGator v7.15.1 ZIP present on the server does contain vendor/symfony/mime, so it appears that the active File Manager dependencies may be incomplete or inconsistent.

The rest of HestiaCP and the File Manager navigation work normally. The problem occurs when opening/editing a file.

What is the official/safe way to repair or reinstall the Hestia File Manager dependencies?

I would prefer not to manually modify Composer-generated autoload files.

Thank you.

We will release tomorrow morning 1.10.3 that will fix the issue

If you can’t wait do the steps you suggested

The issue is caused because we don’t load the dev depencies. Causing it missing on our side
