Mint 19 installation snags

zealbert · 10-25-2018, 10:22 PM

Does anybody know what this means: it appears each time I try to update, after I get notified by the update manager. I just upgraded from Mint 18.3 to Mint 19 (Mate, 64 bit)

E: grub-efi-amd64-signed: installed grub-efi-amd64-signed package post-installation script subprocess returned error exit status 1
E: shim-signed: dependency problems - leaving unconfigured

I'm now having trouble re-installing my VPN, keep getting installation error messages, which mention this "efi" thing; could it be related?

Thank you

I'm sure that's not the whole error message you got - it helps to post the whole message, not just a few snippets of it.

Anyway, from the error messages you have posted and what I'm suspecting; it seems there has been a problem with the grub-efi-amd64-signed package for whatever reason and the shim-signed package depends upon it.

I would see if flushing apt's cache helps or not. Run the following in a terminal:

Code:

sudo apt-get clean

Let us know what happens...

The upgrade appears not to have been entirely successful.

Please paste, within CODE tags (https://www.linuxquestions.org/quest...og.php?b=36313) and/or with the line of equals signs removed, the output from:

Code:

dpkg -l | grep -v "^ii"

I am sorry, but that really is the whole message I am getting; a little window opens, and that's what is there. I copied and pasted the whole thing.
When I closed it, another error message window appeared; maybe I should have copied that too. I will next time there is an update.
The command you gave me, sudo apt-get clean didn't result in anything. It just asked for my password, which I entered, then nothing. Just back to the cursor.
Oh, I just got another update, and here it is: So first, I get this, which I sent you before:

E: grub-efi-amd64-signed: installed grub-efi-amd64-signed package post-installation script subprocess returned error exit status 1
E: shim-signed: dependency problems - leaving unconfigured

Then, I get a message "not all changes and updates succeeded", and I expanded the details, and copied and pasted it, as below:

dpkg: error processing package shim-signed (--configure):
dependency problems - leaving unconfigured
No apport report written because the error message indicates its a followup error from a previous failure.
Errors were encountered while processing:
grub-efi-amd64-signed
shim-signed
E: Sub-process /usr/bin/dpkg returned an error code (1)
A package failed to install. Trying to recover:
Setting up grub-efi-amd64-signed (1.93.8+2.02-2ubuntu8.7) ...
Installing for x86_64-efi platform.
grub-install: error: cannot find EFI directory.
dpkg: error processing package grub-efi-amd64-signed (--configure):

dpkg: dependency problems prevent configuration of shim-signed:

Package grub-efi-amd64-signed is not configured yet.

dpkg: error processing package shim-signed (--configure):
dependency problems - leaving unconfigured
Errors were encountered while processing:

This is all I got. Hope it helps!

Hydrurga,
Sorry, I didn't understand your instructions. Do I just paste what you wrote in a terminal? I am not savvy at all, so please walk me through this step by step, I'd appreciate it.

hydrurga · 10-26-2018, 08:24 AM

Thanks for that output (please also see my post before for more output that would be useful).

From your output, I think the key line is:

Code:

grub-install: error: cannot find EFI directory.

Grub expects to find the EFI directory at /boot/efi, so let's check to see if it is mounted:

Code:

mount | grep /boot

Did you do an in-situ upgrade from Mint 18.3 to Mint 19 or a fresh install?

Also, I just tried to install soundkonverter, and got this message:
E: grub-efi-amd64-signed: installed grub-efi-amd64-signed package post-installation script subprocess returned error exit status 1
E: shim-signed: dependency problems - leaving unconfigured

I did an install via a usb stick, over my mint 18.3. I didn't do it, someone who knows quite a bit about all this did it.
I will try what you suggested now.

And this, after it said "not all changes were applied":

zealbert · 10-26-2018, 08:40 AM

Sorry, did you want me to type this in a terminal?
mount | grep /boot
I did that, and nothing happened.

hydrurga · 10-26-2018, 08:46 AM

Ok. It appears that your EFI partition isn't mounted. I'm not of much use to you as I have a BIOS setup, not a UEFI one. Hopefully someone else with a UEFI setup can talk you through how to determine where your EFI partition is and how to mount it.

Can you contact the person who installed your system for support? It looks like they improperly installed the system.

zealbert · 10-26-2018, 08:48 AM

Yes, I will. Thanks for your help!

Do let us know how you get on. If the person who set it up is unable to help and no-one with a UEFI system here steps up to the plate, I will help you to get it sorted - it's just that I will be flying a little blind.

Perhaps this will help

Looking for the EFI partition:

Code:

~$ sudo fdisk -l
Disk /dev/sdb: 1.8 TiB, 2000398931968 bytes, 3907029164 sectors
Units: sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disklabel type: gpt
Disk identifier: F972E6E8-5C1E-4A0E-8D9C-74B85B4AC0F7

Device          Start        End    Sectors   Size Type
/dev/sdb1          34     262177     262144   128M Microsoft reserved
/dev/sdb2      264192    1288191    1024000   500M Microsoft basic data
/dev/sdb3     1288192    1492991     204800   100M Microsoft basic data
/dev/sdb4     1492992    2516991    1024000   500M EFI System
/dev/sdb5     2516992  104916991  102400000  48.8G Microsoft basic data
/dev/sdb6   104916992  145876991   40960000  19.5G Linux filesystem
/dev/sdb7   145876992  186836991   40960000  19.5G Linux filesystem

To see where and how the EFI partition is mounted:

Code:

~$ mount | grep sdb4
/dev/sdb4 on /boot/efi type vfat (rw,relatime,fmask=0077,dmask=0077,codepage=437,iocharset=ascii,shortname=winnt,errors=remount-ro)

Entry in my /etc/fstab for EFI partition:

Code:

UUID=30B5-AFE3                            /boot/efi     vfat    umask=0077,shortname=winnt 0 2

Thanks for responding!
The person who had installed Mint 19 came back, and re-did it with the EFI partition. Everything is working fine now. Thanks for everyone's help!
