I would like difference with regard to safety between installing software by adding a PPA or by using a .deb package.
For example, I found a specific application in GitHub and I want to install it. The instructions to install include two options:
Option 1 - Via PPA
sudo add-apt-repository ppa:ppaName sudo apt-get update sudo apt-get install software Name
Option 2 - From Package
wget https://github.com/path/to/software/download/v1.0/SoftwareName.deb sudo apt-get install gdebi sudo gdebi SoftwareName.deb
Since the reliability of a PPA depends of many factors, is safer install it by downloading a deb package?
Are there any safety differences between these two methods?
