This is an easy installer for installing ROS noetic, PX4 (mavros), gazebo,... on ubuntu 20.04.
Basically this installs ROS(noetic) + Mavros + gazebo and all of the dependencies (Qt, JRE, etc) on ubuntu 20.04.
This is the replacement for the same script used for ubuntu 18.04 (link) updated for ubuntu 20.04 and ros noetic.
Please note that this script installs the latest versions of cmake and git along with optional installation of anaconda3 (Anaconda3-2021.05-Linux-x86_64.sh to be exact).
In my experiments, I noticed having an up-to-date cmake and git solves several issues, so its recommened to install them as well.
If you have them installed previously, then nothing will be installed.
If you don't like installing anaconda3 or have it installed already, you can press Enter or explicitly choose "No" when it comes to installing it, and carry on without it.
I recommend going without anaconad3 installed, although having it installed by the script causes no harm, but it might give you headaches down the road in other ros projects.
And finally your catkin (ROS build system) workspace is created at ~/catkin_ws/.
Simply do :
wget https://raw.githubusercontent.com/Coderx7/ros-noetic-PX4-easy-installer/main/ubuntu_sim_ros_noetic.sh
chmod +x ubuntu_sim_ros_noetic.sh
./ubuntu_sim_ros_noetic.sh
Follow the on-screen instructions.
لطفا قبل از اقدام به نصب نسبت به استفاده از یک وی پی ان و تنظیم دی ان اس شکن اقدام کنید تا در فرایند نصب بعلت تحریم با مشکل مواجه نشید 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
nameserver 127.0.0.53
