In this question a deb-package was linked without any hint to the potential danger of bypassing Ubuntu's package management. I know that in the Window's world setup.exe are quite common, but common does not mean secure and also does not mean advisable.
So I was wondering:
- Should we never link to external deb-packages?
- Should we only use packages from trusted sources? What are trusted sources?
- Should we add them but always add a "be careful what you download"-hint?
