I made a COSMIC DE PPA for easy installation on Ubuntu LTS releases. Maybe someone will find it useful
Packaging require newer wayland, xwayland, mesa (I copied kisak’s mesa for this purpose) and rust compiler than that shipped with Ubuntu 24.04. They are in the same PPA so installation is straightforward.
For installing I recommending using --no-install-recommends flag so we will avoid GNOME desktop.
This is unofficial PPA so you installing it on your own risk I’m currently using it and testing so it basically works but keep in mind, everything may happened Thanks!
Any tips to go from a regular Ubuntu installation to this?
Well If you are on Ubuntu desktop 24.04 LTS than just add PPA and run sudo apt install cosmic-session. It will install required packages with cosmic-greeter and while installing greeter you will be asked for default login manager. Just select cosmic’s one or keep gdm3 as default.
After that you can select your desktop in login screen as always
Im running this already on Ubuntu 24.04 LTS Server installation so it contains only COSMIC as DE, so i recommended running --no-install-recommends since it’s avoid installing GNOME as some of the package dependency
Since PPAs are not officially supported, please add a disclaimer to your post and also the Launchpad page.
Yeah, added note in this post, thanks On Launchpad I saying it right on the beginning it’s unofficial so I think it might be enough, if not I can add a disclaimer too
It might also be useful to know which Ubuntu versions or flavours this was tested on.
i’m currently using it on Ubuntu 24.04 LTS (server) version so pretty bare bones but it works! It’s working pretty well or even better ^^
My plan is to provide support for latest LTS releases. So for now it’s 24.04
Very nice. I have high hopes for this DE for 26.04. Do you plan to follow the upstream development closely (keeping the ppa up to date)? Do you want feedback, bug reports etc?
Finally I can see this topic. Sorry I just renamed myself and can’t access previous account.
So let’s keep on this
Hi, please also provide instructions how to undo this if something goes wrong and thank you for your hard work and sharing.
Thanks for advice! I added instruction on Launchpad description
Very nice. I have high hopes for this DE for 26.04.
Yes, me too!
Do you plan to follow the upstream development closely (keeping the ppa up to date)?
Actually I’m using this build so I will update it. Not sure if I will build only tagged versions or pick master branch from time to time.
I love this desktop and using it for few months already
Do you want feedback, bug reports etc
Yeah sure! For now directly via launchpad or later when I create a repo with CI/CD for it.
I just pushed v1.0.1 changes to repo. It’s building right now
#edit
btw. I cleaned gnome dependencies a bit.
For installing you don’t need to pass --no-install-recommends anymore.
Just install it for bare bone with sudo apt install cosmic-session or with additional COSMIC’s packages: sudo apt install --install-recommends cosmic-session
I think probably some release yes. I guess not a 26.04. COSMIC want to be rolling release desktop. Not like the others so it might be hard to keep with Ubuntu LTS philosophy. However PPA would suit it just fine. Of course it require some removing from official Ubuntu, but you need to do this one time.
I don’t want to burst any bubbles, but it is not simply a matter of wishing something would be an official flavour.
To become an official Ubuntu flavour, a distribution must be approved by the Ubuntu Technical Board and adhere to strict community and technical guidelines.
