Let’s return to the browser. The main hopes were on it because built-in Chromium is limited in DRM functionality. Indeed

In general, the Raspberry Pi is pretty suitable for studying software development basics or just for learning and experimenting with Linux. Even the absence of a disk is rather a plus here — even if the system is completely destroyed, the SD card can just be pulled out and the new image can be saved again in five minutes.

First, we need to configure Wi-Fi, for which we edit the 50-cloud-init.yaml file using the sudo nano/etc/netplan/50-cloud-init.yaml command. Add access point parameters to it:

Wi-Fi: Wi-Fi itself works, but it is not shown in the system settings. “Wi-Fi Unavailable” is displayed, and the list of networks is empty. (At the same time, the command ifconfig shows a normally working wlan0 adapter in the running status and an IP address.)

The installation process is not much different from the standard Raspbian installation. We need to download the system image, write it to a micro SD card, and start the device. The images themselves can be downloaded from ubuntu.com/download/raspberry-pi:

I first decided to go through all the steps from scratch, choose the console version Ubuntu Server 64-bit 20.04.1 LTS (because this version has a “RECOMMENDED” status), and install the missing components myself. After download and boot, we get into the standard Ubuntu console.

As for Linux itself, terminal commands, bash, and other stuff, everything works in a standard way as expected, with no difficulties. Here’s an example of displaying the system load in htop with a running browser and several programs in the background:

ing Italian in 2017 with a class at university, the only previous knowledge that I had was my fluent French and my basic Spanish (which definitely helped, needless to say). Nevertheless, I was a complete beginner in Italian and could not form sentences or understand a native speaker yet.

network: ethernets: eth0: dhcp4: true optional: true version: 2 wifis: wlan0: optional: true access-points: 'MYWIFIPOINT': password: '12345678' dhcp4: true

Audio: By default, for an unknown reason, the headphone output is always active — there is no sound on the display speakers. I can switch the sound to HDMI in the settings, but it all reverts back after a reboot.

Ubuntu 20.10 Groovy Gorilla has official support for the Raspberry Pi 4, and as announced, the Raspberry Pi is now a “first-class citizen” for this version. Let’s try to figure out what came of this and how “first class” corresponds to reality.

The Galaxy S10 smartphone showed twice the download speed (64.3 MBps) and the same (19.6 MBps) upload speed using the same Wi-Fi. Perhaps the speed still drops due to the metal case of the Raspberry Pi, but 33 MB/s is sufficient for real use.

YouTube works fine, but I heard annoying clicks when playing audio. This should not be the case, because the manufacturers of the Raspberry Pi 4 promised support up to 4K. As it turns out, this is a known issue in Linux when playing audio over HDMI and can be solved by editing the /etc/pulse/default.pa file, after which the sound became normal.

After rebooting, we can check for an internet connection with ping 8.8.8.8 command, and if everything works, we can install Ubuntu desktop. Run the commands sudo apt-get update, sudo apt-get upgrade, and finally sudo apt-get install ubuntu-desktop. The process takes about 30 minutes, after which we can reboot the system and get a full U.

The load of the CPU cores is not high, but video playback in the browser increases it to about 70%. If we make a kind of stress test by opening several browser tabs with large documents (YouTube, graphics editor, file explorer), then the CPU load will go to the maximum (which is not surprising), but there is enough free RAM with even a large margin.

With programming, everything is quite good. Of course, the Raspberry Pi can’t replace most professional desktops, but in general, it can run almost all programming languages and frameworks, from Python to Fortran.
