Hello @jirka11111, first all of welcome to the balena community 🙂

Can you please explain the sort of application you want to develop and deploy?

In general, we advise the new users to go through out getting started docs like this one:

> **[Get started with Raspberry Pi 4 and Python - Balena Documentation](https://www.balena.io/docs/learn/getting-started/raspberrypi4-64/python/)**

We believe our docs do a good job introducing the balena concepts and how a newcomer like yourself could quickly get started. We appreciate hearing your feedback on how we could improve.

To talk specifically about the error you see: `apt-get` command doesn’t seem like available. What’s the base image you are using? Can you share your dockerfile?

Depending on the base image (as specified in the dockerfile), you will use a different command to install packages. We have additional documentation that explain Docker:

> **[Docker Masterclass - Balena Documentation](https://www.balena.io/docs/learn/more/masterclasses/docker-masterclass/)**

Finally, if you are using balena base images, you could use the convenient method `install_packages` for installations as explained here:

> **[Balena base images - Balena Documentation](https://www.balena.io/docs/reference/base-images/base-images/#installing-packages)**

Let us know how it goes and if we can help with anything specific.
