Hi, Please see: https://bugs.debian.org/982241 It looks like cdrkit / genisoimage wont be available in the next Debian 12 (and therefore probably it will also be dropped in Ubuntu). As per the bug report: "I'm told xorriso and libburnia are alternatives and are alive and doing well." Would it be possible to switch to that? Cheers, Thomas Goirand (zigo)
