I Can't Enable Secure Boot (Arch Linux & Windows 11)

Hello, 

I have Arch Linux and Windows 11 (which I need for gaming) installed on two separate disks. However, I can't enable Secure Boot. I followed the instructions with `sbctl`, but it didn't work. When installing Arch Linux, I had selected both the regular Linux kernel and the `linux-zen` kernel. I’m not sure if the issue is related to that. 

This is my first post on the forum. I’d really appreciate any help.

sudo sbctl verify 
Verifying file database and EFI images in /boot/efi...
✓ /boot/vmlinuz-linux is signed
✓ /boot/efi/EFI/GRUB/grubx64.efi is signed
invalid pe header

Thank you for your quick response. I'm sharing the `sbctl` output. I'm still very new to Linux, and even more so to Arch Linux, so I need guidance step by step.

Re: I Can't Enable Secure Boot (Arch Linux & Windows 11)

Please edit posts rather than make new ones if nobody has replied, it makes the thread easier to follow.

What is the output of

sbctl list-files

Please also share the archinstall log.

It would probably have been better to wait until opening your upstream bug report, this might just be a PEBKAC issue.

I followed the instructions with `sbctl`, but it didn't work

That's far too vague. We need to see the exact commands & configuration files, along with a full description of the actual problem, preferably with full error messages and any pertinent logs. Thanks,

Hello. Thank you for your warning. From now on, I will edit my message when there is a development, as you said.

I don't know how to share the Archinstaller log. I tried the following commands, but I didn't get any results:

ls -l /var/log/archinstall.log
cat /var/log/archinstall.log
 ls -l /var/log/archinstall.log
find /var/log -type f -iname "*archinstall*"
sudo find /var/log -type f -iname "*archinstall*"
journalctl -xe | grep -i archinstall
ps aux | grep archinstall
journalctl -b | grep -i archinstall

The sbctl instructions I followed (https://github.com/Foxboron/sbctl) are as follows:

# sbctl status
Installed:	✘ Sbctl is not installed
Setup Mode:	✘ Enabled
Secure Boot:	✘ Disabled

# sbctl create-keys
Created Owner UUID a9fbbdb7-a05f-48d5-b63a-08c5df45ee70
Creating secure boot keys...✔
Secure boot keys created!

# sbctl enroll-keys
Enrolling keys to EFI variables...✔
Enrolled keys to the EFI variables!

# sbctl status
Installed:	✔ Sbctl is installed
Owner GUID:	a9fbbdb7-a05f-48d5-b63a-08c5df45ee70
Setup Mode:	✔ Disabled
Secure Boot:	✘ Disabled

// Reboot and enable secure boot in the bios!
# sbctl status
Installed:	✔ Sbctl is installed
Owner GUID:	a9fbbdb7-a05f-48d5-b63a-08c5df45ee70
Setup Mode:	✔ Disabled
Secure Boot:	✔ Enabled

I don't know what PEBKAC means, but I hope it's an issue that can be solved easily. I've been dealing with it for about two days, and being a novice Linux user makes the process more difficult.

By the way could the issue be caused by GRUB? Do you think a clean installation with a different bootloader would solve the problem?

Re: I Can't Enable Secure Boot (Arch Linux & Windows 11)

Please don't full-quote unnecessarily, it makes the thread harder to follow.

sbctl list-files

Looks like you've had the ESP mounted under both /boot/ and /boot/efi/ at some stage. What does /etc/fstab say about your mountpoints? Also check the content of /proc/self/mounts to see what's actually mounted where.

Check /var/lib/sbctl/files.json for redundant entries and also regenerate the initramfs images but only after you're sure the ESP is mounted correctly.

Probably best to re-run your grub-install & grub-mkconfig commands with the correct mounting to make sure they're aligned.

I don't know how to share the Archinstaller log

Did you check /var/log/archinstall/install.log, as per archinstall(1)?

The sbctl instructions I followed

That cannot be complete, there are no signing commands listed

Did you read https://wiki.archlinux.org/title/Unifie … ot#Signing & https://wiki.archlinux.org/title/GRUB#S … ot_support?

EDIT: and provide a link to this thread in the GitHub bug report, it will probably be useful for foxboron.

Re: I Can't Enable Secure Boot (Arch Linux & Windows 11)

Hello, 

Honestly, as a newbie, I decided to go for a clean installation rather than struggling with issues and switched my bootloader choice from GRUB to systemd. At the same time, I followed the secure boot steps from the attached video. As a result, secure boot was successfully activated.

Thank you for your help.

Long live LINUX, long live FOSS, long live FREEDOM!

Please don't post queries here again unless you reinstall following the official guide or with archinstall.

Random Youtube videos are unsupported here so please ask the video creator for help if you have any problems with your current system.

I already reinstalled using archinstall. 

Additionally, I shared the solution that fixed my issue and provided feedback to help others who might face the same problem in the future. Is this your understanding of gratitude? I thought I was on an Arch forum, not a Windows one. A community with strict rules and a lack of courtesy would fit better over there!

Re: I Can't Enable Secure Boot (Arch Linux & Windows 11)

The stipulation to only used approved installation methods is purely pragmatic — if you follow the official guide then you should have a very intimate knowledge of the configuration details, given that you applied them yourself; similarly with archinstall a full log is provided to show helpers on the forum exactly how the system has been configured. Following a random Youtube guide does not give us this knowledge and makes troubleshooting much more difficult so it does seem reasonable to require those Youtubers provide a support channel for their "guides". There is also the fact that the vast majority of "guides" out there are error-ridden and/or out of date, further adding to any support burden.

tl,dr: get off your high horse

Re: I Can't Enable Secure Boot (Arch Linux & Windows 11)

Everything you say may be formally correct. But in a community, there has to be more than just formality. After all, I mentioned that I am a new Linux user. Of course, I may have shortcomings in giving proper feedback. If you also think there are things I did incorrectly or not entirely right, then show me how to do them correctly by giving examples. 

Therefore, the person your condescending and commanding tone makes seem arrogant and superior here is not me. Such behavior discourages new Linux users and pushes them toward closed-source software like Windows or macOS! So my advice to you would be to try winning people over, not driving them away!
