I have already bought a brand new raspberry pi 5 but cannot use any ubuntu versions other than 23.10. I need to install ros 2 in pi 5 but i can't do it with version 23.10. So is there any way i can use lower ubuntu versions on pi 5 or any way i can install ros 2 in version 23.10. Thanks
So this is the error I get whenever I try to use sudo apt update on my terminator
I heard that people usually use VirtualBox to install Ubuntu in windows and ROS. But I wanted to know which one is better in terms of software compatibility. Is Virtualbox is better for ROS or Multipass?
This issue may be related to ROS completely, however, at present, I am not sure about the source of the error. Hence I am posting it in this big community.
I am trying to install ROS Melodic on Ubuntu 18.04.2 LTS PC. Unfortunately, the command sudo apt install ros-melodic-desktop-full failed. Below is the output of the same command, when running again:
ravi@lab:~$ sudo apt install ros-melodic-desktop-full
Reading package lists... Done
Building dependency tree
Reading state information... Done
ros-melodic-desktop-full is already the newest version (1.4.1-0bionic.20190204.220757).
You might want to run 'apt --fix-broken install' to correct these.
The following packages have unmet dependencies:
python-rosdistro-modules : Depends: python-rospkg-modules but it is not going to be installed
E: Unmet dependencies. Try 'apt --fix-broken install' with no packages (or specify a solution).
It suggests running apt --fix-broken install which I did but it doesn't solve the issue. See below:

I am not able to proceed. I found a possible workaround here which suggest removing python-rospkg package but it didn't work either. Please see below:

I have no clue now about fixing it. Below is the more information about the PC:

Any workaround, please?
I'm currently trying to run Gazebo on WSL in Ubuntu, using Xming, however, it crashes without even fully opening. I can see the orange loading screen when I call it through terminal roslaunch turtlebot_gazebo turtlebot_world.launch, however, it almost immediately dies.
It's pretty frustrating, as I've been working for this issue for a whole day now.
Here's what I get in the terminal:
