Nemo file manager as an alternative to
GNOME Files and employed the
GNOME Display Manager to replace
LightDM X display manager.
Saraswat had previously created several other Linux distributions, including the server-focused Krob Linux. About his motivations for starting Ubuntu Unity, Saraswat stated, "I had used Ubuntu 17.04 back when I was 8 ears oldand I really loved Unity7, so when Unity7 was discontinued by Canonical, I wasn't happy and wanted to bring it back. I created this project to give Unity7 a new life". Saraswat was ten years old in 2020 when he first released Ubuntu Unity. He indicated at the time that his goal was to eventually have the distribution accepted as an official Ubuntu "flavour".
Ubuntu Unity became a recognized flavour starting with the 22.10 release.
Releases
Ubuntu Unity 20.04 LTS

For those who've lauded Ubuntu's choice to switch to GNOME, fear not—Ubuntu is sticking with GNOME. Unity, on the other hand, has made its return, thanks to the likes of the Ubuntu Unity desktop distribution. It's a fresh take on an old, once defunct favorite".[
Marius Nestor reviewed the release in ''9to5Linux'', stating, "I took Ubuntu Unity Remix 20.04 for a spin and it brought back good old memories for me. The spin looks great and works like a charm".][
Eric Londo of ''Linux++'' reviewed the new release, saying, "Yes, this was the old Unity I used to know and love, but somehow it felt fresher. As I worked to regain muscle memory over the key-bindings (GNOME really can take over the way you control your system XD), the experience was smooth, graceful, and fun in a way that is unique to the Unity experience. During the testing, I did not encounter a single issue that I would deem detrimental or even annoying. Everything from the Dash to the file manager and theming appeared to be just where it had left off, not skipping a beat. Congratulations to Rudra Saraswat on bringing Ubuntu Unity back to life".]
Adam Hunt of Full Circle, wrote, "this release can't be termed "groundbreaking" or "a game-changer", but it does show exactly where the mainstream Ubuntu could have been today if it had not left Unity 7 behind for the Gnome Shell".
The first point release was made on 6 August 2020, on the same day as the other Ubuntu flavours and included fixes for a number of small issues.
A 19 October 2020 review by John Perkins in ''Make Tech Easier'' faulted the release for its high idle CPU and RAM use, and noted, "the main thing that sticks out as a con to me is the wallflower factor. Nothing about Unity really sticks out. Aside from the search function, the appearance, look and feel of Unity doesn't have anything special enough to keep me coming back".
Ubuntu Unity 20.10
This standard release came out on 22 October 2020.
The version incorporates Linux kernel

booting. It also adds fixes and updates for many user interface issue, including adding the Compiz settings manager, with many plugins and effects. It also introduces a new default theme of Arc-darker, new wallpaper and a new Yaru-Purple theme and icon theme.
In a review of the first alpha version, Marius Nestor wrote in ''9to5 Linux'', "I took it for a test drive, and, to my surprise, everything works a lot faster than version 20.04".
A review of the final release on ''Debug Point'', Arandam Giri praised Ubuntu Unity's efficiency and how it improved user productivity.
A January 2021 review in Full Circle magazine noted: "Ubuntu Unity 20.10 is a very strong release. It builds on the success and all the tech press attention that the first release garnered and shows developer commitment to taking Ubuntu Unity further, with the goal of gaining official status. Adding the CompizConfig Settings Manager, more window and icon themes, and a wide array of wallpaper choices, plus settling on Thunderbird for email and Nemo as the default file manager, shows that this development cycle is going to be focused on sharpening the user experience. This makes it worth tracking this distribution along the road to the next LTS version, 22.04 LTS, due out in April 2022. If this release is any indication, we should see good things in the future".
Ubuntu Unity 21.04
Ubuntu Unity 21.04 is a standard release, made on 22 April 2021.
This version uses Linux kernel 5.11 and included a new Yaru-Unity7 theme, plus a new transparent launcher icon. It also included new wallpapers and a new Plymouth

app. In addition, this release adds the missing notifications for volume and brightness changes, and improves support for Snap apps".
A review in the August 2021 issue of ''Full Circle'', concluded, "Ubuntu Unity 21.04 is another strong release from the development team. The focus of this development cycle has been on including more user 'look and feel' choices, while providing the efficient Unity 7 interface and a good range of applications. It is a formula that seems to be working, as each release, so far, has accumulated improvements".
Ubuntu Unity 21.10
Ubuntu Unity 21.10 is a standard release, that came out on 14 October 2021.
This release included an updated version of the Unity user interface from version 7.5.0 to 7.5.1, incorporating updated indicators and migration of the glib-2.0 schemas to the gsettings-ubuntu-schemas.

The project also adopted a new simplified Ubuntu Unity logo by Muqtadir and Allan Carvalho.][
This release also marked the start of migration of the project to GitLab and the design of a new website, due to expanding need and increased traffic. The developers also indicated the project was beginning a move to the lol Snap store, as an alternative to the existing Canonical Snap store at snapcraft.io.][
A review in the February 2022 edition of ''Full Circle'' noted, "Ubuntu Unity 21.10 is not as strong a release as was expected and has some outstanding issues that were present at the time of its release. The lack of the Unity Tweak Tool, installed by default or even that can be installed and run, means that the themes provided cannot be properly accessed. I think it is okay to put out a "standard" release that has unsolved bugs like this, but the developers need to clearly explain the issue in the release announcement and indicate when it is expected to be fixed".]
Ubuntu Unity 22.04 LTS
This fifth release of Ubuntu Unity was made on 21 April 2022 and is a long term support release, supported for three years, until April 2025.
Changes in this release include adding Flatpak and the Flathub repositories by default. Different installation files for BIOS

A review in Full Circle magazine noted. "Ubuntu Unity 22.04 LTS is a solid release with no obvious bad habits or issues identified. The return of the Unity Tweak Tool is a welcome addition to this release, as it works well, and this means Ubuntu Unity 22.04 LTS is better than its predecessor, 21.10. Ubuntu Unity continues to offer its users a lot of customization choices, plus a unique mix of default applications from the GNOME and MATE desktops".

Ubuntu Unity 22.10
Ubuntu Unity 22.10 is the first release as an official flavor and was released on 20 October 2022.
As the first release as an official Ubuntu flavour, Ubuntu Unity 22.10 was hosted on the Canonical's official service, cdimage.ubuntu.com. It also completed the move from libadwaita applications to MATE desktop alternatives. Unity packages were moved to hosting as Ubuntu "Universe" packages and the Ubuntu Unity desktop could also be installed on other Ubuntu flavours by simply adding the ubuntu-unity-desktop metapackage.
