- [x] I found the information, but it was incomplete
- [ ] I found the information, but it was confusing

### Issue Description

What about replacing the line (at the beginning of the page)

`$ sudo apt install apache2`

with:

`$ sudo apt update && sudo apt install apache2`

That would be a reminder to update apt DB before proceeding with Apache2 installation.

I didn't do it myself because I'm a newbie on this Wiki and I don't want to create confusion.

Open the Apache2 installation page at https://ubuntu.com/server/docs/how-to/web-services/install-apache2/ and locate the initial installation command. Check the surrounding instructions for consistency, then update the command if appropriate so the documented apt database refresh is included; done means the page clearly presents the intended installation sequence.
