Describe the bug
Unable to get my laptop Dell G3 3779 BIOS updated using UEFI capsule update to the latest firmware (which is 1.25.0 LVFS: G3 3X79) with consecutive fwupdmgr refresh --force && fwupdmgr update.

Steps to Reproduce
fwupdmgr refresh --force && fwupdmgr update - No message about successful update and no prompt to reboot.
It only shows:

There are updates available for your platform, but they've been embargoed for years. I'll ping the right people.

[CragW]

@RomanPerekhrest Can you pl. download bios.exe from support.dell.com and install it with /usr/share/fwupd/install_dell_bios_exe.py?

[RomanPerekhrest]

It has given me this (gcab folder?):

[roman@roman-pc Downloads]$ python /usr/share/fwupd/install_dell_bios_exe.py G3_3579_3779_1.25.0.exe

Restart now? (Y/N) 

Of course, after restart, it did not set the firmware updated.

[CragW]

Do you have gcab installed on your system? if not, please install it first.

[RomanPerekhrest]

I've installed gcab, the command python /usr/share/fwupd/install_dell_bios_exe.py G3_3579_3779_1.25.0.exe run successfully, but there's still the old firmware:

 [roman@roman-pc ~]$ sudo dmidecode -s bios-release-date
07/18/2018

(it somehow doesn't apply)
