#RaspberryPi – New Raspbian image for 2020-Feb-05

Buy Me A Coffee

Hi!

I remember last time I download and updated my Raspberry Pi with the latest Raspbian image, because it was the week before the Caribbean Developers Conference, and I deal with a couple of unexpected issues with the new version.

After the Regional Innovation Summit in Seattle, one of the draft posts that I have is related to a new Raspbian version released on 2020 Feb 05. See Release notes in the references section below. There are a couple of very interesting features here:

File Manager

The File Manager has a couple of new and interesting options. It’s still not as good as Double Commander, but I like the new features. This is the old FM

And in the new one we can find that the Places, which allow us to directly access to our most frequent locations, is not collapsed by default. And with this new space, we can access more easily to other resources like USB disks and more.

Another big one, is the [New Folder] icon in the toolbar. Yes, this small one feature makes our lives much more happy! And there are new icons and more.

Code the Classics

Remember that I got my amazing [Code the Classics] book? Now all the samples for the book are included as an option to be downloaded from the Recommended Software in the Games section.

raspbian now includes code the classics in the recommended software

Display Options

I mostly use my device via VNC (which was also updated), however sometimes I got some issues when I connect my device to an external monitor. In the previous configuration, we didn’t have any option to manage this:

In the new version we can enable or disable the following options

  • Underscan
  • Pixel Doubling
  • Composite Video
  • Screen Blanking

#RaspberryPi – Where is my Add/Remove programs? let's use Synaptic

Buy Me A Coffee

Hi!

When I wrote about the latest version of Visual Studio Code working on the Raspberry Pi, I realize that I used a couple of commands to find an installed application.

The following command will list all the installed apps

sudo apt list --installed

Which is great, but hard to read in bash mode. So that’s why I use grep to filter for the app I want.

sudo apt list --installed | grep -i code-oss

So far, so good. The command did the trick, and I got my result: app name, version and details. However, as a long time Windows user, I was wondering if Linux users have a visual interface for this. And then I found: Synaptic.

The command to install Synaptic is maybe the last command we will use to install or uninstall an app

sudo apt install synaptic -y

And then we can launch the app using this command, and it’s need to be with sudo permissions (learned in the hard way)

sudo synaptic

At this moment, I can browse in the all list of apps. And I can quickly perform a search for my installed Visual Studio Code.

I get the result, with details, version and more.

And if you are wondering what’s the main difference with the bash command? So, I didn’t need to search and learn a command, the universal visual clue of the magnifier, or the search button were good enough for me.

Playing around with the app, I found I can display much more information for each installed app. Which is great, because I start to understand the idea and concepts of dependencies, where Linux install software, etc.

Happy coding!

#RaspberryPi – The amazing single command to install UI mods in #Raspbian Lite (yes, my memory need this …)

Installing Packages in Raspberry Pi lite!

Hi !

Quick post today. And a memory backup one. I just spend 30 minutes trying to install a desktop UI in a clean lite RaspberryPi install. And I missed and missed again the command.

The right command is

sudo apt install raspberrypi-ui-mods

And that’s it. Now is here, so I can search me and find the solution.

Context: I use the [Raspbian Buster Lite] distro for the Raspberry Pi. In 10 minutes I got the SSH enabled so I can perform most of my operations remotely from my computer.
