Install Raspberry Pi OS

Aldous

There are several operating systems that can be installed on the Raspberry PI. The following details how to install the Raspberry Pi Foundations own OS, Raspberry Pi OS.

OR. You can download Raspberry Pi Imager from the Raspberry Pi website and do it all automatically. But where is the fun in that.

There are 3 versions available:

1: Raspberry Pi OS with desktop and recommended software

2: Raspberry Pi OS with desktop

3: Raspberry Pi OS Lite

This is how to install No: 1 (Though it holds pretty much true for the other 2 versions)

Download the OS from the official Raspberry Pi website and make a note of the integrity hash. Unzip the downloaded file to a directory. (I usually leave it in the Downloads directory)

You can check the integrity hash by running a checksum utility against the downloaded file to see if the sha256 sum is the same as that from the website. I use a Linux machine to do the following:

In a terminal go to the directory location that you have saved the downloaded file too. For example the Downloads directory.

Run the following command from the command prompt within the Downloads directory

sha256sum OSMC_TGT_rbp2_20190424.img

The result will appear a few seconds later. If the resulting alpha/numerical sequence matches the one from the Raspberry Pi website the file should be safe to use.

To install the .img file to a micro sd card open a terminal at the directory containing the image file.

Type at command line:

sudo dd bs=1M if=OSMC_TGT_rbp2_20190424.img of=/dev/sda

(To view the progress of an operation, add to the end: status=progress)

Once that has completed after a couple of minutes, put the micro sd card in the Raspberry Pi and connect up to a monitor, power supply and keyboard. Switch on and let it go through the setup process.

The first thing to do is change the default password on the Raspberry Pi. Go to

Make a note of the new password as you will need it when you run some of the following commands.

You can now connect the Raspberry Pi to the internet via wireless or cat5 cable.

Open a command prompt by

and type:

sudo apt update

sudo apt install ufw

sudo ufw enable

Restart the Pi.

This will install a basic firewall for when you go online.

You can check it is enabled by typing from the command prompt:

sudo ufw status

At the command prompt type:

sudo apt update

sudo apt upgrade

Then type: Y

This should install all the software updates available.

You should now have a fully installed and updated Pi.

It is usually wise at this point to make a full back up of your working install. There is software on the Pi that lets you do this. Simply go to

You can play around with the various settings to change the look of your system i.e. change the background, font size, location of the taskbar etc.

X ( or Twitter ) Part 2

Aldous

It looks like the Application Programme Interface ( or API ) on X and the X feed app for my blog will only allow 1 update per week for my X feed. I could buy the X feed app for the blog which should give me up to 12 updates a day, but I do not really want to spend any money on stuff like that at the moment.

Food is a bigger priority.

So I will just leave it as is for now. And maybe see if there is a work around for the problem. Of course I could just use a different app or X equivalent. That’s a job for this weekend.

The rest of the site seems to be working okay though.

Addendum ( 12 hours later ): X just updated my post. Looks like it is just weekly updates only.

DIY

Aldous

I have only really done some basic DIY in my little flat. This week though I expanded my horizons and dismantled my built in fridge/freezer and moved it to a different wall. It backs on to the wall in my bedroom and I am tired of hearing it rumble on at night. Call me crazy but I think an uninterrupted nights sleep is kind of important …..

At least temporarily until I acquire a new one. A smaller and hopefully quieter fridge/freezer.

Not an easy job and I managed to fall down the stairs while taking out the doors and surrounding woodwork. Which was surprisingly heavy. I’m just glad I did not cause any major damage. To the stairs and myself. Though I have banged my knee again. Amazing how much damage that knee has had over the years.

Now I have to go out and get something to fill in the hole in the wood flooring. And weirdly a hole in the wall. Not sure why that is there. And then repaint everything.
