Cannot update to php 5 to 7 in linux mint?

问题

I just want to update PHP 5 to PHP 7 and I got below error after adding this line "sudo add-apt-repository ppa:ondrej/php"

Adding PPAs is not supported

I am using Linux mint 17 and my web server is Nginx. How to fix this? Is there any alternative

回答1:

To use the add-apt-repository you need to install software-properties-common or python-software-properties , just run the following command:

sudo apt-get install software-properties-common python-software-properties

Then run:

sudo add-apt-repository ppa:ondrej/php

Alternative methode:

You can add dotdeb repository to your sources.list then install PHP 7
