#VSCode – Installing Visual Studio Code in a #RaspberryPi, a couple of lessons learned – @code


Now that I have my amazing Raspberry Pi 4 with 4GB RAM, it’s time to see how serious the device is. So, I decided to install and use some developers’ tools in the RPi. My dev list will be something like this

  • Python
  • Some ML and AI Python packages
  • GIT
  • Arduino
  • Visual Studio Code

It’s been a while since I installed VSCode in the device. The last time I did this, I needed to download the code from GitHub and compile the tool in the Raspberry Pi. As far as I remember this was a +25 min process.

Lucky for us the process can now be much simpler, thanks to Headmelted (see references). Now, we only need a single command to install VSCode:

. <( wget -O -
https://code.headmelted.com/installers/apt.sh )

Install process started! Or Maybe not because I found this amazing GPG error

There a public GPG key used to verify the package and the SH script somehow does not download it (I think the ARM RPI version is still not defined). So, before the previous command, I need to run these commands

wget https://packagecloud.io/headmelted/codebuilds/gpgkey
sudo apt-key add gpgkey

Then run this command

curl -L https://code.headmelted.com/installers/apt.sh | sudo bash

Now we have Visual Studio Code installed!

But, yes another but, you may note that the tool open and display a black window. Again, I need to go deeper on the details, but the latest version does not work well. There is some context information on GitHub (see references), and the proposed solution is to rollback to a previous version

sudo apt-get install code-oss=1.29.0-1539702286

And we also need to disable the automatic updates on this tool

sudo apt-mark hold code-oss

And now, yes, we got a fully functional Visual Studio Code in our Raspberry Pi!

Happy Coding!

  1. Dear Sir,
    First of all, I want to thank you about your blog about object detection using YOLO. Thereafter, I’m a beginner in AR, VR and I want to try deploy an example of object detection on HoloLens using YOLO. Therefore, can you please give me some details about the instructions to deploy the YOLO library to Unity to HoloLens. Certainly, I will be among the most followers of your blogs. Thank you for helpfulness.
    Best regards


  2. I was unable to install VS Code because the GPG key wasn’t created. I used the following:

    wget https://packagecloud.io/headmelted/codebuilds/gpgkey -O- | sudo apt-key add –

    but got the following error. I could use some advice, please.
