Yeah. I wanted to build a custom theme from source, and installed all the dependencies. Tried the theme, realized it had the usual issues just like every other theme, uninstalled it. Then I uninstalled everything I needed to build it, as the terminal history was still there and I could tell exactly what was installed. Guess what? apt would’ve nuked my desktop environment if I didn’t stop it, almost as if what I had installed was a required dependency. Pretty sure it was optional though, since everything was more or less working before installing

–Edit
Forgot to mention the custom theme was for qt5ct, not for the desktop environment
