curthooks: EFI variables are not supported on this system (EFI v1.1 by Apple)

I reproduced the issue on some Apple hardware I had access to yesterday. What is interesting so far is that while the command `efibootmgr` fails:

# efibootmgr
EFI variables are not supported on this system.

It succeeds when specifying efivarfs for the LIBEFIVAR_OPS environment variable:

# LIBEFIVAR_OPS=efivarfs efibootmgr
BootCurrent: 0000
BootOrder: 0000,0080
Boot0000* ubuntu
Boot0080* Mac OS X
Boot0082*
BootFFFF*

This seems to indicate a failure in the efivarfs_probe function.

After more debugging, I found out that efivarfs_probe fails because of:

statfs("/sys/firmware/efi/efivars/", 0x7ffedb26c490) = -1 EINVAL (Invalid argument)

which seems closely related to bug 2034705.

Hello,

A fix for the desktop installer was published to the latest/candidate channel.

If somebody who is affected wants to do some testing before we make it available for a broader audience, here would be the steps to run:

1. Boot the 23.10.1 desktop ISO
2. Once the "Welcome to Ubuntu" window shows up, asking you to choose the language, close the window.
3. Refresh the installer using the following command:
   $ sudo snap refresh ubuntu-desktop-installer --channel=latest/candidate
4. Run the installer using the "Install Ubuntu 23.10.1" icon on the bottom right of the desktop.
5. Go through the installation steps normally.

Thanks,
Olivier

Thank you!

I'll give this a shot after work tonight. Looking forward to it

Perfect and thank you for your very valuable work!
It worked for me without any errors!

This worked for me on my 2014 27" iMac

Hello,

Does anyone know if this fix was removed from -channel=latest/candidate?

I just tried and now installation is hanging on "Warning subiquity_server: Unable to find the subiquity_client package."

This is on a macBookPro11,2 using the 23.10.1 installer with refreshed ubuntu-desktop-installer.

Thanks!

Okay I'm totally new in ubuntu and I don't know sh*t about commands and stuff. I tried the fix latest/candidate thing but it says error snap "ubuntu-desktop-installer" is not installed and I'm stuck I don't know what to do someone please help

Hello,

I had the exact same issue trying to install 23.10.1 on a Macbook Pro Mid-2014 (dual boot with Bug Sur). Performing the above steps to update the installer to the latest candidate resolved the issue on my setup.

Thanks!

Hello,

Thank you to everyone who tested the revision in latest/candidate.

Today, the desktop team promoted this revision to stable/ubuntu-23.10. Therefore, the installer should now natively offer you to upgrade to 0+git.4edfab2b provided that you are connected to the Internet.

This should eliminate the need of a manual refresh of the snap.

Thanks,
Olivier

A fix for this issue has been released in Subiquity 24.02.1 for Ubuntu live-server, and also in the latest build for Ubuntu 23.10.1 desktop. You can find this build now on the stable channel for both those cases.

To pick up this fix, please allow the installer snap to update, or you can use the directive `refresh-installer: { update: yes }` in autoinstall to achieve the same result.
