Operating System Compatibility List

Not everything is bug-free, so you might want to the check also Fixes in Progress about the state of their upstreaming.

GNU/Linux

Distribution	Version	Architecture	Reported by	Notes
Adélie	1.0-beta1	ppc64	awilfox	Needs the easy-kernel-power8 package instead of easy-kernel. KDE 5 is stable. Firefox occasionally crashes when context-clicking.
Debian	10 (2018-05-28 weekly DVD ISO)	ppc64le	JeremyRand	Seems to work fine. KDE crashes occasionally, but that might be unrelated to running it on POWER9. Works fine as a KVM host via virt-manager (tested with Debian 10 as the guest). Be warned that the installer will enable the contrib repos (without your knowledge or consent), which is bad from a software freedom standpoint.
	10	ppc64	awilfox	Only tested in KVM-PV. Using Adélie easy-kernel as kernel, Debian Buster userland.
	9	ppc64le	nashimus	Requires 4.16 or newer kernel. Installed Debian testing net install, set apt sources to Debian stable and downgraded, keeping 4.16 kernel. Most VMs failed to boot before updating qemu to 2.12.0.
Fedora	28	ppc64le	Sharkcz	only bare metal verified for now, you might want to enable SharkCZ's COPR repo for not-yet-upstreamed updates
	28	ppc64le	nashimus	May need to manually specify inst.stage2, during install. Workaround Bug
	28	ppc64	Sharkcz	discontinued in Fedora 29
Gentoo	n/a	ppc64le	luke-jr	Once installed, works fine.
Gentoo	17.0	ppc64	MarcusC	XFCE4 and virt-manager verified
