fwupdmgr-1.6.1: fwupd update: /usr/libexec/fwupd/efi/fwupdx64.efi cannot be found

[m1027]

I believe this must be something trivial...

To reproduce:

• use fwupd-1.6.1 (on Gentoo here)
• fwupdmgr refresh
• fwupdmgr update

Result:

Devices with no available firmware updates:
 • UEFI dbx
Devices with the latest available firmware version:
 • Embedded Controller

/usr/libexec/fwupd/efi/fwupdx64.efi cannot be found

Expected behaviour:

• update Intel ME

Some notes:

• This error message is new since 1.6.1.
• The file /usr/libexec/fwupd/efi/fwupdx64.efi is indeed nowhere on the system.
• A fresh reinstall, after clearing all related files and caches did not help.
• gcap: 1.4
• In the past I had success using fwupdmgr, using older versions <1.5.9.

Is fwupd-efi installed? Did you also disable the EFI binary subproject when building fwupd?

Thanks for the hint. Indeed I believe it is not the case yet.

Here is the according bug report: https://bugs.gentoo.org/791307.

If you are sure that's the reason feel free to close this issue.
