+1, just wanted to add that this isn't a recent regression. It's been broken for months now (I'm using aur/flameshot-git). It saves the screenshot just fine, but nothing gets copied to the clipboard, as in, it doesn't even overwrite the current clipboard contents.

@wait-what I wish there was an Ubuntu package for the git version though (I'm using Ubuntu 24.04)

I had this issue today, but in my case I had to install wl-clipboard package. I am not saying, its your issue, just giving solution that worked for me.
