The following article provides information for you to update the system BIOS in a Linux environment such as Ubuntu.
As Linux and Ubuntu distributions are becoming more popular on Dell systems, there are more situations where a Linux only environment is present.
If your system is listed at https://fwupd.org/lvfs/devicelist, then it supports UEFI capsule updates and can be updated natively within the OS.
Ubuntu 16.04 and later natively notifies you of new BIOS updates. When an update is available, a notification is displayed to flash the update.
If your system or Operating System does not support UEFI capsule updates:
All Dell systems from 2015 and later support flashing an updated BIOS from within the boot menu. Follow the directions below to update the BIOS on these systems.
