I just create the pi desktop image on VirtualBox 6.1.16 64bit using the 32 bit pi image from your link. Set the VM to be 4 gig ram, 16 gig hard disk, linux OS, 32 bit (1 CPU until after the installation, because I forgot to update it). Chose the Install option and it went through without a hitch. Rebooted and now I have a full Rasbian desktop in a vm. So ...

Of course both Pi OS and Ubuntu are Debian-based variants and the written directions on the OpenCPN site for R Pi 2,3, and 4 are correct to specify the Ubuntu PPA for OpenCPN repository. I feel pretty sure I followed those OpenCPN R Pi directions to the letter several times over the past few days as I used the R PI Org's Raspberry Pi Imager to do several ...

The ONLY way is to install a fresh image. This requires a computer and SD Card writer. This can be any computer including the Pi. I routinely write to SD using the Pi.

Installing software does not affect the state of the Pi. All the state is held on the SD card. To re-install Debian you need to write a fresh image to the SD card (or just insert an SD card with a different image).

This is not really a Pi question. Most conventional computers have a BIOS which is in a ROM (containing 32 MB of code). Later models use a different, but similar technique. The BIOS contains all the code required to mount images, initiate hardware etc. but even there require a boot loader on the install medium. The install medium contains code to run a "...

I do not understand why do you use such an error prone procedure. Just install OpenCV from the default repository: rpi ~$ sudo apt update rpi ~$ sudo apt full-upgrade rpi ~$ sudo apt install python3-opencv This fit best to the Raspberry Pi OS and should install without problems. For additional moduls look with: rpi ~$ apt list '*opencv*'

In case someone else encounters the same issue: student@LP3-WS1:~ $ gcompris-qt ... * failed to open vchiq instance student@LP3-WS1:~ $ Gcompris developers gave the solution by mail: you need to add your user to the video group (which is done by default for the default pi user, but not when creating new users). This command should fix it: sudo usermod -a -...

At the default Raspberry Pi OS repository you will find for the r-* packages: rpi ~$ apt-cache pkgnames 'r-' | wc --lines 764 From this 764 packages just install what you need. You will find the version in the package description for example in r-recommended: rpi ~$ apt-cache show 'r-recommended' | grep '^Version:' Version: 3.5.2-1

If you got one of the Raspberry Pi kits that come with the SD card with NOOBS (CanaKit is the most popular one), you can hold shift as the Pi is booting to be taken to the NOOBS install screen. At that point you can pick whatever version you want to install. That being said, if you flashed the SD card yourself, you will have to go through the trouble of re-...

Welcome to the world of Raspberry Pi! Fortunately, the operating system on a Raspberry Pi is typically Linux based, and I assume this is the same for you. If I am understanding your question correctly, then you want to reinstall a browser onto your Raspberry Pi without having to reflash the whole OS. If so, just run: sudo apt-get install chromium-browser In ...
