I just want to add a me too for this bug. I'm not using any custom kernels, but I just have a noninteractive script that does my software updates, so I set UCF_FORCE_CONFFOLD=YES in the script and this causes nothing but problems for grub menu.lst configuration.
Thanks to this bug report, it does seem that I can do this to workaround the problem in my script: unset UCF_FORCE_CONFFOLD export UCF_FORCE_CONFFNEW=YES ucf --purge /var/run/grub/menu.lst update-grub I have spent hours trying to figure out why update-grub would say it found new kernels, yet, never update the menu.lst. There should at least be an error message of some sort if the menu.lst didn't actually get updated with the kernels it said it found. For example, without purging /var/run/grub/menu.lst here is the output of update-grub with no UCF environment variables set: Searching for GRUB installation directory ... found: /boot/grub Searching for default file ... found: /boot/grub/default Testing for an existing GRUB menu.lst file ... found: /boot/grub/menu.lst Searching for splash image ... none found, skipping ... Found kernel: /boot/vmlinuz-2.6.24-21-generic Found kernel: /boot/vmlinuz-2.6.24-19-generic Found kernel: /boot/memtest86+.bin Updating /boot/grub/menu.lst ... done At this point menu.lst does not have the 2.6.24-21-generic kernel. This kernel was installed with my noninteractive script, so UCF_FORCE_CONFFOLD=YES would have been set when it was initially installed. -- ucf and update-grub semantics are incompatible https://bugs.launchpad.net/bugs/239674 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
