Of course now Version 11, codenamed bullseye, is the most recent Debian release that can be considered stable. The first version 11.0 was published on August 14, 2021, and the most latest upgrade, version 11.3, was released on March 26, 2022.

Debian history

In 1993, on August 16, debian Linux was first introduced to the public by Ian Murdock; Linux distribution was a new concept at the time, and the goal of developing a Debian distribution was to be non-commercial, free, and in line with the principles of the GNU and Linux projects; As a result, the project was financially supported for one year (November 1994 to 1995) by the Free Software Foundation; At first, many people thought that the Debian project that was presented by several programmers; It has no destiny but to disintegrate and it fails.

It is interesting to know that the Debian developer group created this distribution without any financial idea and it was voluntarily, and in their spare time, they developed this distribution and did not receive any money for it; So many people expected the project to fail, but contrary to popular belief, it turned out differently; In addition, Debian survived, it developed , and in less than 10 years, this distribution became known as the most unique Linux distribution in the world, and so far more than 120 distributions based on it have been released, and there are more than 50,000 software packages for debian. It is even designed for 8-processor architectures and supports a variety of system and PC architectures.

Under these circumstances, the founder of the free software movement named Richard Stallman, due to disagreeing with some of Debian’s explanations, designed software called Virtual Richard M. Stallman. This software was responsible for reviewing the packages installed in the Debian distribution and reporting software that is not free.

Disadvantages of Debian OS

Debian despite its advantages and features, The complex and time-consuming process of its development and testing created problems; These problems were due to delays in updating Stable versions, which are usually Debian Stable versions provided every 1 to 3 years. This caused users to use test versions until the bug-free version was released, and the same was true for software packages. Also until a new version is released, The software version belongs to 6-7 months ago. Another disadvantage of Debian is that it does not support Delta updates such as Delta RPM.

Testing version

This version is expanding its software packages and is waiting in line for stability; The Testing version is for error testing, which provides the latest software enhancements for testing. Also, the Testing version has more updates compared to the stable version, but its disadvantage is that it can not receive security packages at the right time; The latest beta version of Debian is the bullseye.

Unstable version

Unstable or Sid version that most people know by this name; The Debian OS development process is complete in this version, and this is an experimental version that has been developing; The difference between this version and the testing version is that users give feedback in the testing version. The unstable version of Debian allows developers to actively submit code and influence the success of this testing version, so we recommend this version for developers, and using it will not be suitable for all users.
