I recently upgraded one of my Debian Bullseye machines to Bookworm. The machine's main purpose is to run Virtualbox to allow me to experiment on disposable VMs rather than real hardware.
Now when I do "apt update" I get this message: .W: https://download.virtualbox.org/virtualbox/debian/dists/bullseye/InRelease: Key is stored in legacy trusted.gpg keyring (/etc/apt/trusted.gpg), see the DEPRECATION section in apt-key(8) for details. I've thoroughly RTFM in search of a clue as to how to fix this, but I can't figure out what I'm supposed to do. Has anybody else seen this? If so, what did you do? And did it help? Thanks in advance! Rick PS: As an aside, it appears that the VirtualBox developers at Oracle waited until Bookworm was officially released before they started working on getting a bookworm version of their software, so I'm still using the Bullseye version -- which seems to work fine. Presumably, fixing this problem would be one of the things they might want to do before releasing a new version... (One can hope, anyway...) Would it be worth filing a bug-report to Oracle? If so, does anyone know how to do that?
