Hi, I’m trying to upgrade the PHP version on a site, I followed this [thread](https://discourse.roots.io/t/how-to-update-the-current-php-version/19387) and it worked nicely on my development site - I basically changed all instance of PHP “7.1” in the trellis directory to “7.4”, and required a PHP version of at least 7.4 in composer and ran composer update.

I happily pushed the update to the staging site, but when I attempted to provision the server, I received the following error:

```
TASK [Install Python 2.x] ************************************************************************************************************************
    System info:
      Ansible 2.3.0.0; Linux
      Trellis at "Update PHP from 7.1 to 7.4"
    ---------------------------------------------------
    Shared connection to 107.170.41.149 closed.

    fatal: [107.170.41.149]: FAILED! => {"changed": false, "failed": true, "rc": 100, "stderr": "Shared connection to 107.170.41.149 closed.\r\n", "stdout": "/usr/bin/python\r\nE: Unmet dependencies. Try 'apt-get -f install' with no packages (or specify a solution).\r\n", "stdout_lines": ["/usr/bin/python", "E: Unmet dependencies. Try 'apt-get -f install' with no packages (or specify a solution)."]}
```

The staging server cannot be provisioned, and when I run `php -v` on the server it says it’s running PHP 7.2.

How do I update PHP? I am avoiding doing it manually, because my gut’s telling me there’s a special roots way.

Below is the verbose output of the error from provisioning the staging server:

Thanks for your answer strarsis. It looks like the error message is similar, but the environment is totally different :frowning:
