Hire Deeply Vetted Debian Developer

Cases when Debian does not work

1. Outdated or incompatible hardware: As a stable Linux distribution, Debian focuses on stability and long-term support. However, this means that it may not always have the latest drivers and support for cutting-edge hardware. If you have recently acquired new or uncommon hardware, there is a chance that Debian might not work optimally or may not have full support for it.
2. Proprietary software and drivers: Debian takes a strict stance on free software and prioritizes open-source solutions. This means that if your workflow heavily relies on proprietary software or drivers that are not available in open-source alternatives, you may encounter difficulties while using Debian. While there are workarounds and some non-free software can be installed, it might require extra effort and could potentially impact system stability.
3. Limited official support for multimedia codecs: Debian prioritizes open-source codecs due to licensing and patent concerns. Therefore, some popular multimedia codecs, such as MP3 or H.264, may not be readily available in the official Debian repositories. While you can install these codecs from third-party sources or use alternative open-source codecs, it might not be as convenient as with distributions that include them by default.
4. Less user-friendly for beginners: Debian is known for its stability, security, and customization options. However, it may not be the most beginner-friendly distribution for those new to Linux. The installation process can be more complex compared to some other distributions, and configuring certain aspects of the system may require more technical knowledge and familiarity with the command line interface.
5. Less emphasis on user experience and aesthetics: Debian’s primary focus is on stability and functionality rather than providing a visually appealing user interface out-of-the-box. While Debian offers different desktop environments to choose from, they may not have the same level of polish and aesthetic appeal as some other Linux distributions that prioritize user experience.
