As far as I know, this is par for the course and how it has been for a long time, particularly because many of the GRUB settings are inherited from Ubuntu. You get the same result out of `lsb_release`. It may not be ideal, but this is how it is.
As I hope you all know, `update-grub` pulls from /etc/default/grub and /etc/grub.d. Currently, the former specifies "GRUB_DISTRIBUTOR=`lsb_release -i -s 2> /dev/null || echo Debian`" which will ultimately result in using "Ubuntu." It's not clear what package this comes from (`apt-file find /etc/default/grub` fails to find it), so that will make it hard to fix in any permanent fashion. My guess, though, is that if you look upstream in Debian, you'll find it has the same specification. That being said, I'd say that this is going to be darn hard to fix. Additionally, I would repeat the old Lubuntu motto: "Lubuntu *IS* Ubuntu." You can build it off of a regular Ubuntu distro, it uses the Ubuntu repos, etc. It's Ubuntu. So it makes sense to keep it as is. Consider this, too: what if you take your Lubuntu and strip out all the Lubuntu bits and install all the Xubuntu bits. What should GRUB call it now? More importantly: how would it know which one it is automatically? So really, the issue is that there's no great way to fix this that's going to work for all scenarios. Because of that, I'm going to call this Won't Fix. If you would like a solution, please change the GRUB_DISTRIBUTOR string in /etc/default/grub and run `update-grub`. Something like "GRUB_DISTRIBUTOR=Lubuntu" would be reasonable. ** Changed in: ubiquity (Ubuntu) Status: Confirmed => Won't Fix -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1409209 Title: After installing Lubuntu from USB stick, GRUB mistakenly lists Lubuntu as Ubuntu To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/ubiquity/+bug/1409209/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
