Missing dependencies and HTTPS/Let's Encrypt improvements

[linprofsshared]

Hi,

Great script — installation works well, but I encountered a few issues that break the setup on Debian.

Missing dependencies:

Rustup is not installed by default. Cargo cannot be used without installing rustup first. The following command is required:

curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh -s -- -y

The package libmagic-dev is required by OpenVAS components and should be added to the dependency list.

HTTPS and Let's Encrypt support:
I have implemented modifications to:

• run gsad on port 443
• use Let's Encrypt certificates
• include automatic certificate renewal using systemd or cron
• update the gsad.service override file

If you want, I can open a PR and merge these changes into your branch.

Best regards,
