Remove apt upgrade during dependency installation

[pascal-zarrad]

Describe the bug
apt upgrade is being executed during dependency installation. As apt update is required, we should not execute an system upgrade during psh installation.

To Reproduce
Steps to reproduce the behavior:

1. Execute the installer with a missing dependency
2. sudo apt upgrade is being executed during installation

Expected behavior
sudo apt upgrade is no longer being executed during installation
