When I try to run sudo update-grub, I get the following error: 

    Generating grub configuration file ...  
    /etc/grub.d/10_lupin: 26: /etc/grub.d/10_lupin: data: not found

Any ideas what this could mean or how to fix it?
Here is the contents of my 10_lupin file: http://pastebin.com/nDZ9v5sJ

  • Where did you get that 10-lupin file. What is it for? – Pilot6 Jul 28 '15 at 18:51
  • @Pilot6 It's from /etc/grub.d/ . I believe it is part of grub. Other than that, I don’t know much about it. – Guinea Pig Jul 28 '15 at 18:53
  • I do not have this file. It means that you installed it for some reason. If you do not know what is it for, then just delete it. – Pilot6 Jul 28 '15 at 18:55
  • Well these people happen to have it: http://askubuntu.com/questions/453411/ubuntu-14-04-not-booting-after-error-message-tmp-could-not-be-mounted – Guinea Pig Jul 28 '15 at 18:56
  • Do you have a wubi install? – Pilot6 Jul 28 '15 at 18:57
  • @Pilot6 Yes, I do. Forgot to mention that. Sorry. – Guinea Pig Jul 28 '15 at 18:58
  • Wubi is obsolete. I am afraid, you will not get support for it now. – Pilot6 Jul 28 '15 at 18:59
  • Officially wubi is still supported - precise has 3 more years of support, and wubi has not yet been removed from any isos and is present to download for all releases and is present on all released .isos. (12.10, 13.04, 13.10 and 12.04.x point releases) http://askubuntu.com/questions/449486/windows-installer-for-ubuntu-14-04-lts-onwards – Guinea Pig Jul 28 '15 at 19:05
  • That is true. But not many people use it. It will be hard to get support. That's it. – Pilot6 Jul 28 '15 at 19:07
  • And wubi does not support Windows 8 as well. – Pilot6 Jul 28 '15 at 19:09

Your /etc/grub.d/10_lupin contains an error in line 26:

data otdir="${prefix}/share"

should be

datarootdir="${prefix}/share"

To restore that file just reinstall package lupin-support

sudo apt-get install --reinstall lupin-support

  • If your file /etc/grub.d/10_lupin contains more than one error, it is easier to restore the whole file. I added reinstalling of package lupin-support. – ngng Jul 28 '15 at 22:21
  • Thanks so much, my question is part of a wider issue, in which I cannot install or remove packages, because some obsolete kernel is half configured. I have tried everything, so hopefully this should fix it and I should be able to configure the kernel and then remove it. – Guinea Pig Jul 28 '15 at 22:25
