Hello, this might be solved by [1]. As far as I see the dependency chain goes through education-desktop-other to chromium, which depended to sse3-support.
It might have started with 7df9e46cc a few month ago and ended with 98718255f, unfortunately it does not mention a specific bug. Kind regards, Bernhard [1] https://salsa.debian.org/chromium-team/chromium/-/commit/98718255f00a55fdf319796d2bb55ff36390b711 [2] https://salsa.debian.org/chromium-team/chromium/-/commits/bullseye/debian/control
