So regarding the "mangled message" in Raven's notification tab: should I log an improvement task for the notifications in Raven to prevent this kind of mangling in the future? Or was the "mangling" not done by Raven?

I can confirm: new version 1.5.1 in unstable fixes the issue!

1.5.1 release notes: https://github.com/yakyak/yakyak/releases

Update: this issue has not occured anymore in the past few months. Can be closed for now.

Device/hardware detection is part of fwupd.

Note: fwupd-1.0.0 released.

More information about vendor support here: https://en.wikipedia.org/wiki/Fwupd

The current canary version that is available on the 3rd party packages site doesn't work anymore. It forces you to download 0.0.14 (tar.gz or dev) to continue.

Encountered this as well when trying to boot 1.2.1 in gnome-boxes.
Could boot 12 iso though.

The dots please! :)

Yep, that's the same guide I found on the wiki. It only explains how to create a bootable medium and boot into "live" Solus, but no installer guide :)

Does the "next" button change to "finish" on the last step? That's the part that was unclear :)
