For the life of me, I cannot figure out how to get it. KDE is updated but no Oxygen theme and I cannot find a place to download it that isn’t a decade out of date. Any help, please?
It’s delivered as a seperate package in the repository. You need to install plasma-oxygen package with DNF.
Open up the program: Konsole
Copy and paste the following line into it:
sudo dnf install plasma-oxygen oxygen-icon-theme
If it asks for the password, just type in your login password and hit enter
Easy. Thank you both
How would the casual user know that, though?
My first instinct was to go look for it in either the Global Theme area, or even the “Get New…” button and looked for it before giving up and finding this thread by chance.
Not trying to sound like a complainer, but that theme was pretty sweet so I’d think they would want to put it up front and center. I’m still new though.
At least I asked a few weeks ago and at least you found this thread 
Don’t worry. I thought the exact same thing. I looked for it straight away in Discover and was surprised that the search came up empty. Specially since they made all that noise in the announcement of Fedora 44 KDE that the Oxygen theme was back.
