Oh, I made a mistake. As described here.
chromium-browser-stable-103.0.5060.53-1 as far is we know works OK in hardware systems. For some reason it does crash in VirtualBox. In that situation we normally decide to publish the upgraded packages for folks with hardware systems and leave it up to VirtualBox user to downgrade whatever package does not work in VirtualBox.
So correcting my own mistake and re-publishing chromium-browser-stable-103.0.5060.53-1 for Rolling. It should be available (again) in a few hours or less.
Note: Dadgummit! I hate it when I screw up.
