So the FAQ says EE will install on Debian 7 and 8.
I do a fresh install of Debian 8 on Vultr, do an apt update, and apt upgrade to get the box up to date. I did a reboot of the server and then tried to do the install command displayed on the homepage of EE.
root@vultr:~# wget -qO ee rt.cx/ee4 && sudo bash ee -bash: sudo: command not found
I can get it installed just fine on Ubuntu, but I read that Debian is more secure so I’d rather go with that here.
