WordPress Installation not working

Hello there,

I am trying to install wordpress for one of the sites on my web-server. I am a novice in linux and the whole world of web-servers. But I have had a pretty good experience setting up my linode so far. I have followed the tutorials closely and I have been able to set up the whole LAMP stack. I had a bit of an issue installing php. Basically the tutorial (https://www.linode.com/docs/websites/hosting-a-website) had said to run "sudo apt-get install php5 php-pear" which yielded :

Package php5 is not available, but is referred to by another package.

This may mean that the package is missing, has been obsoleted, or

is only available from another source

I subsequently tired "sudo apt-get install php7.0 php-pear" which worked with the last line reading "Processing triggers for php7.0-fpm (7.0.15-0ubuntu0.16.04.4) …" I then ran "sudo apt-get install php-mysql" which also seemed to work with the last few lines showing "Setting up php-mysql (1:7.0+35ubuntu6) …

Processing triggers for php7.0-fpm (7.0.15-0ubuntu0.16.04.4) …"

So i felt that my php installs where good. So i tried to go ahead an install word press. I currently have 6 websites in my public html folder. From what I understand about wordpress is that I can load and use wordpress as a CMS for any one of my websites. So I tried installing it following the linode tutorial

(https://www.linode.com/docs/websites/cm … -wordpress">https://www.linode.com/docs/websites/cms/how-to-install-and-configure-wordpress). I followed the tutorial to a tee. And I placed the src folder inside the folder of the specific website i wanted wordpress to control. The installation seemed to work. I logged on through cyber duck to see if the files had been placed and I say the zip wordprress package in the /src folder , and the multiple wordpress files in the public html file of the same website. I assumed that if I went to the website (ssstack.net), I would be prompted to set up wordpress. But it only showed me the index.html file i had put on there before. I also noticed that when I went to http://ssstack.net/wp-admin/ it would show the raw code for the wordpress log in page.

So thats my problem. I do not know where I went wrong. I have a hunch, especially after my incorrect php install command, that the linode tutorial is about of date or in correct or something. Also since I followed the Linode Wordpress tutorial, I haven't been able to edit any files in any of websites in my var/www file. I also have a hunch that the permissions i had set have been changed. If any one can help it would be great
