Question: I'm trying to install PyCharm on my Raspberry Pi running Ubuntu Mate. But I don't understand the error message I get.

First I followed this tutorial : <https://linuxize.com/post/how-to-install-pycharm-on-ubuntu-18-04/>

it was just about writing `python sudo snap install pycharm-community --classic`

I received this error `snap "pycharm-community" is not available on stable for this architecture (armhf) but exists on other architectures (amd64).`

Secondly I tried another tutorial using Umake. <https://www.rosehosting.com/blog/how-to-install-pycharm-on-ubuntu-16-04/>

I received this error `Keyerror : 'armhf'`.

What does it mean? It is possible to install Pycharm on a raspberry running Ubuntu Mate?

Answer: 
No, it's not possible to install PyCharm on a Raspberry Pi. The `armhf` error means that the RPi hardware (processor) is not supported by PyCharm. 

**However:** PyCharm does support remote development (after a fashion) on the RPi, but you will have to install PyCharm on a system that runs on supported hardware (e.g. Intel). PyCharm/JetBrains has a [tutorial (several actually) that may help](https://www.jetbrains.com/help/pycharm/remote-development-on-raspberry-pi.html) you. PyCharm's support for Raspberry Pi requires that a series of "helper apps" be installed on your RPi; these "helper apps" facilitate communication and remote control between your development system (Intel-based), and your target system (RPi). There are quite a few of these "helper apps" installed during the process of configuring PyCharm to do remote development on the RPi.

I know this is an old post but I was searching for the exact same question and fond this answer: <https://www.element14.com/community/community/raspberry-pi/blog/2019/09/12/installing-pycharm-on-raspberry-pi>

I have tested it on Twister OS 1.8.2(based on raspberry pi OS) and Ubuntu Mate 20.04 and it works without issues.

TL;DR go to <https://www.jetbrains.com/pycharm/download/#section=linux>

1. Download pycharm
2. Extract and run `pycharm.sh` from the bin folder.
