Excited from recent New Raspberry PI 4 released! news, someone has missed that also a new version of our loved OS has been released.
The new OS is described by Raspberry Foundation as a necessary step for new Hardware. However RPI Foundation guarantees a complete backward compatibility, so that the migration should be painless.
About main updates that involve people using raspberry Pi as server (lite version), security changes have made it harder to hack.
Desktop version, on the other side, gained some minor new features:
- a new button style have been adopted (more similar to a plain button than a phisical button)
- Thonny Python development environment becomes the default phyton editor
- a new CPU Temperature Monitor can be found inside the CPU Usage Monitor
Please find here below main changes referred from the official release notes page about the new Raspbian Buster release:
* Based on Debian Buster * Support for Raspberry Pi 4 hardware * FKMS OpenGL desktop graphics driver and xcompmgr compositing window manager used when running on Raspberry Pi 4 * Screen Configuration application added for use with FKMS driver * Raspberry Pi 4 video output options added to Raspberry Pi Configuration * Uses new PiXflat UI theme for GTK and Openbox * CPU activity gauge plugin no longer shown on taskbar by default * CPU temperature gauge plugin added (not shown by default) * USB ejecter and Bluetooth taskbar icons hidden when not appropriate * Version 74.0.3729.157 of Chromium web browser included * Version 126.96.36.199 of Flash player included * IDLE Python IDE removed * Wolfram Mathematica removed temporarily due to incompatibility with Buster * Display of package sizes removed from Recommended Software * Appearance Settings modified to support independent settings for two monitors * Oracle Java 7 and 8 replaced with OpenJDK 11 * Miscellaneous small bug fixes * On-board 5GHz WiFi blocked by rfkill by default The block is removed when taking one of the following actions: - Selecting a locale in the first run wizard - Setting the WiFi country in the Raspberry Pi Configuration tool or the Network Settings applet - Setting the WiFi country in raspi-config - Providing a wpa_supplicant.conf file through the boot partition - Running 'rfkill unblock wifi' * Boot partition size set to 256M * Linux kernel 4.19.50 * Raspberry Pi firmware 88ca9081f5e51cdedd16d5dbc85ed12a25123201
Please find here the download page for the new OS. The procedure is the same as for Installing Raspbian Stretch Lite in your Raspberry Pi 3 model B. I’ve tried it with my Pi A+ and it is working with no issues.
If you want to upgrade your old PI OS:
- Remember to backup all your data before starting
- In the files /etc/apt/sources.list and /etc/apt/sources.list.d/raspi.list, change every use of the word “stretch” to “buster”
- From terminal, type the command “sudo apt update”
- From terminal, type the command “sudo apt dist-upgrade”
- wait…wait…wait (and type yes if required): also the official page reports that it may require from half an hour to several hours to dowload all
- at the end, RPI will reboot.
RPI Foundatio also refer to some applications not supported but installed with Buster (?????). To remove these:
sudo apt purge timidity lxmusic gnome-disk-utility deluge-gtk evince wicd wicd-gtk clipit usermode gucharmap gnome-system-tools pavucontrol
Please find here the official page.
Enjoy the new Raspbian Buster!
