Public bug reported: A behavior of grub-pc.config does not allow to reach "replacing config file with new version", as shown below in a session listing:
# echo grub-pc grub2/linux_cmdline string acpi=force elevator=deadline | debconf-set-selections # dpkg-reconfigure -f noninteractive grub-pc Replacing config file /etc/default/grub with new version Installation finished. No error reported. Generating grub.cfg ... ... The problematic code introduced in http://bazaar.launchpad.net/~ubuntu-branches/ubuntu/precise/grub2/precise/revision/31/debian/grub-pc.config (lines 24-38) (where it overwrites preseeded values in debconf database with call to db_set): if test -e /etc/default/grub ; then . /etc/default/grub db_set grub2/linux_cmdline "$GRUB_CMDLINE_LINUX" db_set grub2/linux_cmdline_default "$GRUB_CMDLINE_LINUX_DEFAULT" case grub-pc in grub-pc) if [ "${GRUB_TIMEOUT}" != "" ]; then db_set grub-pc/timeout "$GRUB_TIMEOUT" fi if [ "${GRUB_HIDDEN_TIMEOUT}" != "" ]; then db_set grub-pc/hidden_timeout true elif egrep -q '^#?[[:space:]]*GRUB_HIDDEN_TIMEOUT=' /etc/default/grub; then db_set grub-pc/hidden_timeout false fi ;; esac fi Commenting it out makes the above example in listing to work. I dont understand the purpose to update debconf preseed values with those from config file. (assuming db has these already calibrated before adding into db with 'interactive' backend) ProblemType: Bug DistroRelease: Ubuntu 12.04 Package: grub-pc 1.99-21ubuntu3.7 ProcVersionSignature: Ubuntu 3.2.0-35.55-generic 3.2.34 Uname: Linux 3.2.0-35-generic x86_64 ApportVersion: 2.0.1-0ubuntu17 Architecture: amd64 Date: Sat Dec 15 21:04:37 2012 MarkForUpload: True ProcEnviron: LANGUAGE=ru_RU TERM=xterm PATH=(custom, user) LANG=ru_RU.UTF-8 SHELL=/bin/bash SourcePackage: grub2 UpgradeStatus: No upgrade log present (probably fresh install) ** Affects: grub2 (Ubuntu) Importance: Undecided Status: New ** Tags: amd64 apport-bug package-from-proposed precise third-party-packages -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1090768 Title: grub-pc.config prevents replacing with new config file contents To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/grub2/+bug/1090768/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
