For information, ubuntu-24.04 has updated Linux kernel from 6.5.0-28 to 6.8.0-31
The problem reported is only with newer 6.8.0-31, and also failure to reach a working system is only with new kernel. The previous Linux kernel is still available in the Grub menu, and choosing "6.5.0-28-generic" to boot does bring a working system, with the only line containing "cups" in dmesg being: [ 5.404257] audit: type=1400 audit(1715587151.264:47): apparmor="DENIED" operation="capable" class="cap" profile="/usr/sbin/cupsd" pid=1039 comm="cupsd" capability=12 capname="net_admin" -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2065405 Title: cups-proxyd[2318]: segfault at 18 ip 00005975fb88bd75 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/cups/+bug/2065405/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
