Solus (previously known as Evolve OS) is an independently developed operating system for the x86-64 architecture [2] based on the Linux kernel and a choice of Budgie, GNOME, KDE Plasma or Xfce as the desktop environment. [2] Its package manager, eopkg, is based on the PiSi package management system from Pardus Linux, [3] and it has a semi-rolling release model, with new package updates landing in the stable repository every Friday. [4] The developers of Solus have stated that Solus was intended exclusively for use on personal computers and will not include software that is only useful in enterprise or server environments. [5]
On September 20, 2015, Ikey Doherty announced that "Solus 1.0 will be codenamed Shannon, after the River Shannon in Ireland", indicating that "codenames for releases will continue this theme, using Irish rivers." [6]
In July 2016, Solus announced the intention to discard the concept of fixed point releases and to embrace a rolling release model. [7]
In January 2017, Doherty announced that Solus will adopt Flatpak to reassemble third party applications. [8] In August, Doherty announced that Solus also will adopt "Snaps" (next to Flatpak). [9]
On June 13 the same year, it was announced that the developer team had been expanded with Stefan Ric, and Ikey Doherty – previously working for Intel on Clear Linux OS – started working full-time on Solus. [10]
On November 2, 2018, technology website Phoronix published an open letter from original founder Ikey Doherty confirming that he was stepping back from the project, assigning "any and all intellectual, naming and branding rights relating to the ownership of Solus" to the development team "with immediate and permanent effect, acknowledging them as the official owners and leadership of the project." [11]
On January 1, 2022, experience lead Josh Strobl announced his resignation from Solus, after 6 years of involvement with the project. [12] The Budgie desktop environment, originally created as a project internal to Solus, would be split out of Solus and developed independently under Strobl's newly founded Buddies of Budgie organization.
In January 2023, [13] Solus infrastructure suffered an outage which lasted until April 2023. This outage brought down their website, forums, and development platform required to update the system. Their website was restored by moving it from internal infrastructure to GitHub Pages on February 27, 2023. [14] On April 16, in a post on Reddit entitled "Righting the ship", Josh Strobl announced a series of measures aimed at restoring order to the project. [15] This was followed by a blog post "A New Voyage" which provided more detail about the new personnel, and announced the intention to explore re-basing Solus on Serpent OS. [16] Their development infrastructure and forums were restored alongside that announcement [17] and build infrastructure on April 20. [18]
Solus 1.0 "Shannon" was released December 27, 2015. [19] Jessie Smith reviewed the release as part of a feature story in DistroWatch Weekly, a weekly opinion column and summary of events from the distribution world. While he "ran into a number of minor annoyances" [20] such as "Solus panicking and shutting itself down", [20] he concluded that "Solus 1.0 represents a decent start". [20]
Solus 1.1 was released February 2, 2016. [21] [22] HecticGeek blogger Gayan has described Solus 1.1 as a "well optimized operating system", [23] praising significantly faster boot and shutdown times than Ubuntu 15.10. Due to several usability challenges encountered, he recommended to wait another year before trying it out again. [23]
Solus 1.2 was released on June 20, 2016. [24] [25] Michael Huff has described Solus in his review 'Finding Solace in Solus Linux' as a unique and original project for "those who've been reluctant to travel the Linux galaxy". [26]
Solus 1.2.0.5 was released on September 7, 2016. [27] Michael Huff, a programmer and data analyst, wrote in his second review of Solus in Freedom Penguin that "we finally have the power and ease-of-use of a Mac in a Linux distribution" and "that the only people who need to use Solus are those who value their happiness in computing", praising the operating system as only one of few independent projects assured of "a tight cult following with the potential for mass appeal." [28]
Solus 1.2.1 was released on October 19, 2016. This is the last fixed point release of Solus and all future releases will be based on the snapshot model (the OS is now following the rolling-release model). [29]
Solus is considered a curated rolling release. It is a rolling release in the sense that once installed, end-users are guaranteed to continuously receive security and software updates for their Solus installation. Updates become available every Friday.
Solus 2017.01.01.0, a snapshot following the recently adopted rolling release model, was released on January 1, 2017. [30] [31]
Solus 2017.04.18.0, was released on April 18, 2017. [32] [33]
Solus 3 was released on August 15, 2017. [34] [35] [36]
Solus 3.9999 (Solus 3 ISO Refresh) was released on September 20, 2018. [37]
Solus 4.0 "Fortitude" was released on March 17, 2019. Announcing the release, Solus Experience Lead, Joshua Strobl stated that Solus 4.0 delivered "a brand new Budgie experience, updated sets of default applications and theming, and hardware enablement". [38]
Solus 4.1 was released on January 25, 2020. [39]
Solus 4.2 was released on February 3, 2021. [40]
Solus 4.3 was released on July 11, 2021. [41]
Solus 4.4 "Harmony" was released on July 8, 2023. [42]
Solus 4.5 "Resilience" was released on January 8, 2024, and included the new Calamares installer, PipeWire as a replacement for PulseAudio, and a version using the Xfce desktop environment. [43] [44]
Solus is available in four editions:
Ikey Doherty stated that, regarding Budgie, he "wanted something that was a modern take on the traditional desktop, but not too traditional",[ citation needed ] aiming to keep a balance between aesthetics and functionality.
This group is responsible for researching, guiding and influencing matters of technical development in the larger arc of evolution for Solus. The overarching goal is to ensure that Solus remains relevant in a constantly changing computing landscape. As part of its responsibility, it will carefully listen to input from the community and the various stakeholders in Solus.
This group consists of Ikey Doherty, Joshua Strobl, Joey Riches, Reilly Brogan and Rune Morling. [16]
Solus brings updates to its users by means of a curated rolling release model. It is a rolling release in the sense that once installed, end-users were guaranteed to continuously receive security and software updates for their Solus installation without having to worry that their operating system will reach end-of-life. The latter is typically the case with fixed point releases of operating systems such as Fedora and Ubuntu but also Microsoft Windows. Marius Nestor at Softpedia has argued that all operating systems should use the rolling release model in order to decrease development and maintenance workload for developers and to make the latest technologies available for end users as soon as these are ready for the market. [47]
Compared to other rolling release operating systems such as Arch Linux - which provides bleeding edge software, i.e. software so new that there is a relatively high risk that software breakages might occur and render the system partially or completely unusable, Solus took a slightly more conservative approach to software updates, hence the term curated rolling release. In contrast to Arch, Software on Solus was commonly referred to as cutting edge, typically excluding beta software, and was released after a short period of testing (in the unstable software repository) to end users in order to provide a safer, more stable and reliable update experience. By prioritizing usability (curated rolling release) over availability (pure rolling release), Solus intends to make the operating system accessible to a wider target market than Arch Linux, which is mainly aimed at more advanced users possessing in-depth technical knowledge about their system.
Solus is also a curated rolling release in allowing its users to participate in the actual curation process, broadly conceived as the process by which software is selected, maintained and updated (on the server side in the software repositories of the operating system as well as on the client side on the end users computer system). More specifically, and contrary to other operating systems with various 'enforced update mechanisms', a Solus user has the freedom to choose what gets updated and when updates are applied (if at all), except for mandatory security updates.
Solus comes pre-installed with a wide range of software that includes the latest Firefox, Thunderbird, LibreOffice, Transmission and Celluloid. Additional software that was not installed by default is able to be downloaded using the included Software Center. Wireless chips and modems were supported through optional non-free firmware packages.
Package management is done through eopkg. [48] Michael Huff has quoted project founder and lead developer Ikey Doherty that Solus will not be defined by its package manager. [26] In a previous interview with Gavin Thomas from Gadget Daily on February 8, 2016, Doherty stated that as an end user the goal is to actually not interact with the package manager, sharply outlining the project's direction in terms of user experience.[ citation needed ] According to Doherty, the goal is "to actually get rid of it, so the user doesn't even know about it."[ citation needed ] In Solus, the package manager is not intended to be used as a tool to deploy but to build software,[ citation needed ] distinguishing it from less beginner-friendly practices on other Linux-based operating systems.
In July 2015, Solus announced integration of Clear Linux patches to deprecate insecure SSL ciphers, responding to a community post on Google+ by Arjan van de Ven. [55] [56]
In response to security concerns experienced by the Linux Mint project in late February 2016, [57] Solus introduced improvements by providing a global Solus GPG key on its download section. [58] [59] Joshua Strobl, Communications Manager at Solus, announced the separation of official and community mirrors on the download page with official mirrors "to be regularly audited and updated" [58] [59] and "daily integrity checks against every ISO mirror" [58] [59] to be performed.
Within its software center, Solus contains a wide variety of dedicated security software ranging from encryption software such as VeraCrypt to anonymization tools such as Tor.
Solus integrates AppArmor instead of SELinux for restricting programs' capabilities. [60]
Because of user privacy, the Solus project doesn't track users so there isn't a direct and reliable way to measure popularity.
As of July 2021, the DistroWatch website, which records the frequency of page clicks on its own site, ranked Solus 13th in the 6-month page hit rankings, [61] 6th among the most popular rolling release distributions [62] and achieved an average reader-supplied review score of 8.42 out of 10. [63]
Solus 3 was named one of the best Linux distributions of 2017 by OMG! Ubuntu! [64]
Matt Hartley praised Solus in his overview of the best Linux-based operating systems of 2017, as "Perhaps the most interesting distro in recent years...taking a unique approach to a logical user workflow, package management and how they work with the community. I see them doing great things in the future." [65]
Forbes contributor Jason Evangelho mentioned Solus favourably a few times, with respect to gaming [66] and about the 4.0 release. [67]
A Linux distribution is an operating system made from a software collection that includes the Linux kernel and often a package management system. They are often obtained from the website of each distribution, which are available for a wide variety of systems ranging from embedded devices and personal computers to servers and powerful supercomputers.
A light-weight Linux distribution is one that uses lower memory and/or has less processor-speed requirements than a more "feature-rich" Linux distribution. The lower demands on hardware ideally result in a more responsive machine, and/or allow devices with fewer system resources to be used productively. The lower memory and/or processor-speed requirements are achieved by avoiding software bloat, i.e. by leaving out features that are perceived to have little or no practical use or advantage, or for which there is no or low demand.
PCLinuxOS, often shortened to PCLOS, is a rolling release Linux distribution for x86-64 computers, with KDE Plasma, MATE, and XFCE as its default user interfaces. It is a primarily FOSS operating system for personal computers aimed at ease of use.

Snap is a software packaging and deployment system developed by Canonical for operating systems that use the Linux kernel and the systemd init system. The packages, called snaps, and the tool for using them, snapd, work across a range of Linux distributions and allow upstream software developers to distribute their applications directly to users. Snaps are self-contained applications running in a sandbox with mediated access to the host system. Snap was originally released for cloud applications but was later ported to also work for Internet of Things devices and desktop applications.
Zorin OS is a Linux distribution based on Ubuntu with both free and paid versions. It uses a GNOME 3 and XFCE 4 desktop environment by default, although the desktop is heavily customized for users more familiar with Windows and macOS.
KDE neon is a Linux distribution developed by KDE based on Ubuntu long-term support (LTS) releases, bundled with a set of additional software repositories containing the latest versions of the Plasma 6 desktop environment/framework, Qt 6 toolkit and other compatible KDE software. First announced in June 2016 by Kubuntu founder Jonathan Riddell following his departure from Canonical Ltd., it has been adopted by a steadily growing number of Linux users, regularly appearing in the Top 20 on DistroWatch.com's popularity tables.
Budgie is an independent, free and open-source desktop environment for Linux and other Unix-like operating systems that targets the desktop metaphor. Budgie is developed by the Buddies of Budgie organization, which is composed of a team of contributors from Linux distributions such as Fedora, Debian, and Arch Linux. Its design emphasizes simplicity, minimalism, and elegance, while providing the means to extend or customize the desktop in various ways. Unlike desktop environments like Cinnamon, Budgie does not have a reference platform, and all distributions that ship Budgie are recommended to set defaults that best fit their desired user experience. Budgie is also shipped as a edition of certain linux distributions, such as Ubuntu Budgie.
