Update:
For the latest version check out this repository : https://github.com/Coderx7/ros-noetic-PX4-easy-installer

Old:
This installs ROS + Mavros + gazebo and all of the dependencies (Qt, JRE, etc) on ubuntu 20.04.
basically, this is the replacement for the same script for ubuntu 18.04 (link) updated for ubuntu 20.04 and ros noetic.
Please note that it also installs anaconda3. (if you don't like this, you can choose "no" when it comes to installing anaconda3, and carry on without it. the rest of the installation should succeed just fine).
Also, the latest version of CMake and git are installed (if they are not previously installed).

Simply do :

wget https://gist.githubusercontent.com/Coderx7/f917d9af5d756c38dca5c4373a114f10/raw/e28d5f073c554a9b3dbbfb2ab10bb658eb438b06/ubuntu_sim_ros_noetic.sh
chmod +x /ubuntu_sim_ros_noetic.sh
./ubuntu_sim_ros_noetic.sh

Follow the onscreen instructions.

Before going on any further, in order to circumvent sanctions, set the shecan DNS nameserver so the script doesn't fail:
Run:

sudo nano /etc/resolv.conf 

and add

nameserver 178.22.122.100

and then save.
Just note that after restarting your machine, resolv.conf settings will be reset, so a better approach is to make it permanent. to do so, do
sudo apt install resolvconf
and then open:
sudo nano /etc/resolvconf/resolv.conf.d/head
and write:
nameserver 178.22.122.100
and then save it. Finally restart resolvconf by: sudo systemctl restart resolvconf . now to check if everything is OK do:
cat /etc/resolv.conf
this should show you the nameserver we just wrote on top of whatever is in resolv.conf
for me it looks like:

# Dynamic resolv.conf(5) file for glibc resolver(3) generated by resolvconf(8)
#     DO NOT EDIT THIS FILE BY HAND -- YOUR CHANGES WILL BE OVERWRITTEN
# 127.0.0.53 is the systemd-resolved stub resolver.
# run "systemd-resolve --status" to see details about the actual nameservers.
# shekan dns server ip
nameserver 178.22.122.100
