grub-pc fails to remove, rendering lubuntu uninstallable on EFI machines

The relevant error appears to be:

dpkg: error processing package grub-pc (--purge):
subprocess installed pre-removal script returned error exit status 10

Status changed to 'Confirmed' because the bug affects multiple users.

Even if a grub2 developer read this bug, I guess it is not feasible for grub2 to read BIOS configuration (like FastBoot and SecureBoot of Lenovo B50).

In that case, having a list of BIOS configurations that are or are not compatible with grub2 can help a newcomer troubleshoot such cases.

Hi there!
In my case the issue is just with Lubuntu 16,10... I have kali linux installed (kernel 4.8) and no issue.
Both installations were done in EFI mode
My BIOS is "toshiba v 5.10"

Hi,

I had this problem with lubuntu 16.10 using efi & secure boot.
Install worked ok with "ubuntu" 16.10, with efi mode with secure boot turned off

By bios version is Aspire es1-411

If people can comment on this ticket whether the following is true in their case, then the following page can be updated.

"In your firmware, disable QuickBoot/FastBoot and Intel Smart Response Technology (SRT). If you have Windows 8, also disable Fast Startup... Support for UEFI SecureBoot appeared in 12.10 and 12.04.2."

https://help.ubuntu.com/community/UEFI#General_principles

In my case I disabled both FastBoot and SecureBoot so maybe FastBoot was the root cause.

So without fastboot and secureboot, you are able to install lubuntu? Or did you also switch to ubuntu?

Yes after disabling fastboot and secureboot, I didn't see this error and Lubuntu was installed successfully. I didn't try Ubuntu at all.

Grub seams to depend on BIOS settings specific to each vendor (Lenovo, etc) like fastboot and that this irrelevent to which ubuntu distribution we talk about.

Considering that new laptops usually have such settings, that newbies do not really read long pages of documentation like that of UEFI and that ubuntu is "Linux for Human Beings", we need either to fix it or to have a clear documentation for newbies who want to install ubuntu.

I managed to solve my problem. Somehow, my Lubuntu installation started in efi mode, but it only had grub package for mbr. When I downloaded grub for efi, Lubuntu installed correctly.

Strange... I thought it was an error in the way lubuntu was packaged since it only seems to happen with Lubuntu and not with any other flavors. Fastboot and secureboot should have nothing to do with grub-pc's removal.

I am adding the lubuntu-packaging team as this affects Lubuntu and not other ubuntu distributions.

grub is packaged in a way that breaks the installation when BIOS has fastboot enabled.

This most likely has nothing at all to do with Fastboot or Secure Boot. The system appears to be correctly detected as booted in UEFI mode; which will trigger grub-installer removing grub-pc (since it's not needed).

For instance, from the logs:
Nov 4 22:31:02 lubuntu grub-installer: info: architecture: amd64/efi

Can you successfully install using the alternate ISO? It seems to me like that one should work, and we're likely seeing the effect of bug 1649462 (so Phillip would be right that this is an issue with how Lubuntu is "packaged").

I'll run the test here to make sure. This shows we don't have enough people testing ISOs in UEFI mode.

I was able to use a boot repair tool while booted from the installer USB:

http://askubuntu.com/questions/226061/how-to-install-the-boot-repair-tool-in-an-ubuntu-live-disc

That seemed to fix things. Sorry for the delayed response.

The problem was the Windows flash drive. I zeroed it out, and then
installation finished fine. I wanted the flash drive to be the boot drive,
but the installer skipped it, and used the larger drive for all partitions.
The system has been fine ever since.

I'm glad some people managed to fix their issues. I'll mark this bug Incomplete since the original reporter hasn't answered.

To be frank though, it's probably best to avoid using boot-repair if possible unless you really can't do a new install (which shouldn't be an issue if you've just ran into issues with the installer...)

There are dozens of duplicates. EFI installs of lubuntu are completely broken.

 $ lp-bug-dupe-properties -b 1639374 --rtags

It'd be helpful if somebody would test this with the development release of Ubuntu, zesty, which will become 17.04.

I am the original poster. I can't really help a lot. boot repair was not
the best fix but it got the system running. basically, the system never
worked properly and I eventually had to give up and I have been using an
older ubuntu system.

Laptop doing fine, ignoring it's flash drive altogether. Not sure if
security on it was frozen (have read some about that...)

On my homebuild similar issue--wanting Lubuntu on both machines, laptop for
mobility, homebuild for media.

On homebuild, install crashed after shred of purchased single flash drive.
Went back and zeroed it, and then install finished fine.

I like zeroing---kind of like replaning brakes in a car-- slightly
destructive, but man, does it get you up and running!

Matthieu, it does appear to be something special about the lubuntu packaging since it only affects lubuntu, but I have no idea what that something could be. I can't see anything that would cause grub-pc to fail to remove. I have not taken the time yet to try to actually reproduce it with a set -x in the rm script though.

I can't reproduce this on the daily image (tried 20170208, to be precise). This was due to grub-common being in the seed rather than grub2-common; which lead to grub-pc not being on the livefs.

I'll mark this incomplete; if someone can reproduce this on a recent image, please mention it and include /var/log/syslog and /var/log/apt/* from the installer environment so we can see exactly what happens.

I have tested the Lubuntu 16.10 (not daily) installation on a VM in the BIOS Legacy mode. Without internet connection, the installation fails because of missing Grub2-packages in the ISO (known issue). With internet connection (the option "Downloading updates while installing" was disabled to install faster), the installation succeeds successfully.

I suggest to test different installations in UEFI mode:
a) without internet connection
b) with internet connection, "Downloading updates while installing" disabled
c) with internet connection, "Downloading updates while installing" enabled

I have tested the installation of Lubuntu 16.10 in UEFI mode, without internet connection in a virtual machine. At the end of the installation, the installer crashes.

I have tested the installation of Lubuntu 16.10 in UEFI mode, with internet connection in a virtual machine. The option "Downloading updates while installing" was disabled. The installation fails, but the installer does not crash.

I have tested the installation of Lubuntu 16.10 in UEFI mode, with internet connection in a virtual machine. The option "Downloading updates while installing" was enabled. The installation fails, but the installer does not crash.

Two days ago, on another PC I could install Lubuntu 16.10 with this configuration, but today I tried it several times and it failed.

Possible Workaround: "Try Lubuntu without installing", open a terminal and type: sudo apt install grub2-common

After you can install Lubuntu (clicking on the desktop icon, do not reboot!)

When I had the issue, the problem was the flash card security. Zeroing out
the flash card helped some, as I recall. Since then, I switched to Linux
Mint, for multimedia support.

It turns out there was some setting in my BIOS that was keeping the install
from finishing.

I "Reset BIOS to Defaults" and tried again, and it worked. :-/

I was able recover from this issue, by booting a livecd, chrooting in and running 'apt-get -f install && apt-get install grub2-common.

I checked the grub config and it looked good. I also did a "grub install" but that was probably not required.

At this point what I can see is that this was an issue on daily Lubuntu images and has been solved there.

What is left is the 16.10 release image for Lubuntu was pointing to grub-common, but that is insufficient to properly pick up grub-pc and grub-pc-bin on the image as is needed, especially given that lubuntu does not follow recommends.

I wrote a bugpattern for this so duplicates should automatically get consolidated going forward.

Will the bugpattern pick up on dupes regardless of version? I'm also
unclear on whether or not this is a problem in 16.10 or not. I haven't
seen similar complaints there, but cyphermox seems to suggest there
should be. If it is, we should set this back to confirmed.

The Lubuntu download page for 16.10, http://cdimage.ubuntu.com/lubuntu/releases/16.10/release/, has been updated with a warning regarding this bug.

There is no fix for this to do in grub2; and we don't spin new images for non-LTS releases.

I was affected by this bug (report #1684222) and I was able to install Lubuntu 16.04 using the 32bit image. Maybe this could be added in the warning?

One should check if BIOS is configured with legacy or UEFI mode.

- 64 bits package imposes UEFI installation even if the BIOS is in Legacy mode so incoherence in the end (next reboot).
- 32 bit package can be performed in Legacy mode (maybe why 168422 can be performed ?).

More explicit warning messages should be displayed in the installation process. Test of BIOS config not possible ?

This is incorrect; the choice of UEFI or BIOS is entirely up to your
bios/firmware/motherboard -- the 64 bit installation image supports both.

Thank you all for the support. I have installed UBUNTU insted of LUBUNTU
and had not problems.
The PC was an HP with little hardware space 30GB and I thought LUBUNTU will
be a bit lighter.

Thanks again,
Alexe
