Macbook Pro 2011 Latest Os
Thanks for reaching out to the Apple Support Communities! From your message I can see that you have erased the 2011 MacBook Air and are looking to upgrade the OS X from Lion.
You're correct that you need to upgrade to OS X El Capitan before you can upgrade to macOS High Sierra.
Since you're unable to reinstall the Mac OS X Lion through Recovery, see if you can boot into Internet Recovery. To access Internet Recovery, restart your MacBook Air and hold down Option + Command + R. This will allow you to reinstall OS X Lion.
By reinstalling Lion you'll have access to the App Store and you can follow the steps to upgrade to OS X El Capitan: How to upgrade to OS X El Capitan.
Once you have OS X El Capitan running, you can then upgrade to macOS High Sierra: How to upgrade to macOS High Sierra.
Macbook Pro 2011 Os Update
If you're unable to reinstall OS X Lion, you'll need to have access to another Mac to be able to create a bootable USB drive for El Capitan. This article will provide you with the steps to take to create a bootable installer: How to create a bootable installer for macOS.
All the best!

Mac Os Mojave On Macbook Pro Early 2011
As expected, Apple has started shipping new Macs with macOS 10.15 Catalina. We’re still hesitant to recommend upgrading to Catalina, particularly if you use Mail, since reports of email data loss continue. Luckily, downgrading a new Mac from Catalina to 10.14 Mojave is possible for models other than the 16-inch MacBook Pro and the 2019 Mac Pro. Mac scripting expert (and author of the new book Moving to zsh) Armin Briegel has published a guide explaining how to roll back a new Mac that ships with Catalina to Mojave. Unfortunately, the process to install Mojave isn’t straightforward, requiring a Mojave Installer USB drive. It’s particularly fussy if your Mac is equipped with a T2 security chip since you have to set up an account before you can use Security Utility to enable booting from external drives. Regardless, you will have to erase the internal drive entirely before you can install Mojave due to Catalina’s bifurcated drive structure.
