I am expressing interest in Dell supporting all of their computers via LVFS(Linux Vendor Firmware Service)'s tool fwupd.
I was disappointed when I learned that Dell is not actually supporting all of its computers through fwupd. Many of the problems I am experiencing on my new Dell Latitude 5289 2-in-1 would be solved if only I could update the firmware. I know I can't demand anything as I am using a model which doesn't come with official Linux support. But I bought this model to use with Linux anyway because I knew that Dell is involved in LVFS and Dell generally has good Linux support.
If I had known that not all newer models are supported via fwupd I would have bought a 2-in-1 model from some other manufacturer instead who has fwupd support (e.g. Lenovo).
It is nice that there is a documented workaround at least: https://www.dell.com/support/article/ee/en/eedhs1/sln171755/updating-the-dell-bios-in-linux-and-ubun...
If your system is listed at
then it supports UEFI capsule updates and can be updated natively within the OS.
Ubuntu 16.04 and later natively will notify you for BIOS updates. The system will regularly check for BIOS updates automatically. When an update is available, a popup will be displayed to flash the update
Ubuntu 18.04.2 LTS (Bionic Beaver) seems to work fine on every model I have from my 2006 Optiplex GX620 to my new G7 7588 Laptop.
As long as there is at least 2 gigs of ram it appears to be fine AFAIKT.
For older systems and releases of Linux/Ubuntu, the option is to create a bootable USB storage device with a BIOS update.
