"Software" shows me the following:
It offers Install buttons. Click one briefly makes it change, but I can't read what it says because it then disappears quickly. Then a moment later the screen comes back exactly as it was in the first instance and this screenshot.
What does that mean? Can I use "Software" to install BIOS updates? Am I doing the wrong thing? Is it just broken?
PS. Running Ubuntu Gnome 17.04 on Dell XPS15 9550. UEFI boot.
EDIT: Dell thinks it should work from within Ubuntu...
1. Flashing a Dell BIOS in a Linux Only Environment
As Linux and Ubuntu distributions are becoming more and more popular on Dell systems, there are more situations where a Linux only environment is present. UEFI Capsule updates
If your system is listed at https://secure-lvfs.rhcloud.com/lvfs/devicelist External Link 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.
source. Nb. my system is listed in the device list page.
EDIT 2: manually achieved "System" update.
Thanks to @Rinzwind's answer, I manually downloaded the BIOS update from Dell, stuck it at /boot/efi (need to do that with
sudo) and had the Dell install it from the F12 options. Now "Software" only lists the TPM update, which again will not install. Also there's no download for that listed on Dell's site. So I'm not sure what to do about that.
