Debian 10 “Buster”: this is what this new version of Debian will offer us


A few weeks ago, the next version of Debian 10 "Buster" went to a total freeze of functions., version that highlights the addition of UEFI SecureBoot Support among many other additions to the system.

This total freeze marks the stop of the process of moving packages from unstable to test and the intensive testing and troubleshooting phase of lock release began. In special cases, unstable packages can be transferred manually, but this requires obtaining approval from the team responsible for preparing the release.

With that Debian developers have already been working on bug fixes, to have a polished version ready, for release in the summer of this year.

From the details that this new version of Debian will contain that were announced after the development cycle was completely frozen, we highlight the following.

Secure boot support (UEFI Secure Boot Support)

Finally, Debian offers support for the secure boot mechanism, which facilitates the installation of the system in machines with UEFI SecureBoot Support enableo.

No longer will you have to look for ways to disable or bypass this increasingly common solution in teams.

Squid installer

Beginners will no longer have to worry about dealing with the traditional Debian installer running in text mode.

Debian 10«Buster» introduces the Calameres graphical installer, along with the old Debian installer still allows much more than Calameres, but for beginners with Squids now they can install the easiest and fastest system.

Linux kernel 4.19.0

For users of the previous version of Debian, Stretch, it will be a huge leap forward. The 4.9 kernel has been replaced by the 4.19 kernel, with dozens of improvements and patches collectos throughout the years of Linux developers.

As a version of LTS, with an extended support period, this kernel will follow I receivedendo patches for the next five years.


Together with the new system comes a new default Bash 5.0 system shell with dozens of new features and capabilities, including better history management and support for Unix time variables.

/umr / merge

Our Linux distributions follow the path set by Fedora: the end of the historical and now meaningless split in, for example, / bin and / usr / bin, as well as / sbin / usr / sbin, / lib / usr / lib and lib64 and / usr / lib64.

Now TAll files will be linked to their equivalents in / usr, and old directories will get symlinks.

Debian 10 has been conservative for now, however / var / will be saved y / etc / to avoid potential problems when using the containerized system.

AppArmor enabled

In Debian Buster, the AppArmor mechanism will be enabled by default. For security reasons, This is a step forward, but it will require the inclusion of correct policies by system administrators.

Many scripts from previous versions of the system will also need to be modified to maintain current usability.


The new Firewall The default in Debian 10 is nftables. In addition to better and more convenient syntax, it enables better management of IPv6 networks.

On January 1, 2020, the lifecycle of Python 2 will end, specifically version 2.7 still supported.

For developers, this means that you mustn rewrite your software as quickly as possible in Python 3, which does not retain backward compatibility.

Node.js updated

For years Debian offered the older version of the Node.js framework (4.8) by default, forcing users to install a new repository.

Debian 10 brings the current version of 10.15.2, as well as a complete set of tools for working with JavaScript libraries.

OpenJDK updated

Debian 10 will arrive with the most recent version of OpenJDK 11, also provides full support for Oracle's new rapid release cycle, with which heSubsequent versions will appear in the repositories on a regular basis.

Finally, we only have to wait in a few months for the release of the stable version of Debian 10.0

    I work regularly with modern hardware and I really want to install Buster, between the improvement of KERNEL (finally !!) and many other things that Debian needed for a long time, it will undoubtedly improve the long-term compatibility compared to new batch PCs.
