Raspbian GNU/Linux upgrade from Stretch to Raspbian Buster 10

5 March 2020 by Lubos Rendek

The upgrade from Raspbian Stretch to Raspbian 10 Buster is a relatively simple procedure. However, exercise caution, as there is always a chance to break the entire system. The fewer installed 3rd-party packages and services, the more likely you are able successfully to upgrade your Raspbian Linux system.

What’s New

AppArmor enabled per default
Optional hardening of APT
Unattended-upgrades for stable point releases
Substantially improved man pages for German speaking users

How to install the latest NVIDIA drivers on Debian 9 Stretch Linux

18 October 2019 by Nick Congleton

Introduction

NVIDIA graphics cards have long been the favorite for Linux gamers.

Their proprietary drivers have been very well supported for the last few years, and they continue to be.

The open source Nouveau drivers have been far less reliable, mostly due to NVIDIA’s refusal to work with the open source community.

Either way, though, the drivers are available to install on Debian Stretch.

To install Nvidia driver on other Linux distributions, follow our Nvidia Linux Driver guide.

Open Source

For the most part, when you install Debian Stretch, the Nouveau drivers will also be installed.

However, one exception here is the firmware blobs needed for the drivers to reach their full potential.

Before you continue, you should make sure that your graphics card is supported by Nouveau.

Since the Nouveau driver has to be reverse engineered, it tends to lag behind graphics card releases.

You can check your card’s support at https://nouveau.freedesktop.org/wiki/FeatureMatrix/.

Check what Debian version you are running on your Linux system

30 June 2019 by Admin

The easiest way on how to check what Debian version you are running is to simply read a content of /etc/issue file. Example:

root@debian:~# cat /etc/issue
Debian GNU/Linux 9 \n \l

However, the above command may not show the current Debian update point releases. Thus you may get more accurate info with the following linux command:

root@debian:~# cat /etc/debian_version
9.0

Next, you can check for /etc/os-release release file:

# cat /etc/os-release
PRETTY_NAME="Debian GNU/Linux 9 (stretch)"
NAME="Debian GNU/Linux"
VERSION_ID="9"
VERSION="9 (stretch)"
ID=debian
HOME_URL="https://www.debian.org/"
SUPPORT_URL="https://www.debian.org/support"
BUG_REPORT_URL="https://bugs.debian.org/"
