@flohack Perhaps I misread the canonical write-up as to why snaps couldn't run then, but I was under the assumption that snaps couldn't work on the Flo because of some LXC features being unavailable. If that's incorrect, that's awesome and makes me wanna try to get Anbox up and running on the Flo!
I was also unable to create a LXC container when I attempted on my Flo last, claimed it was missing some sort of kernel support (I can't remember the exact message, but I'm going to be reinstalling UT here soon, so I can attempt again!) and was the same reason Libertine hardcoded itself to chroot if running on a vivid-based device iirc (unless I misunderstood that requirement, in which case, my apologies for the misinformation then!)
Also, I mis-spoke in my previous reply, Flo is on 3.4.0, not 3.5.0 ^_^; (EDIT: I also want to mention that I had forgotten to state that I was writing using what I had thought was the case from Vivid, I admit I haven't tried LXC on Xenial yet)
Btw, I'm literally ALWAYS happy to learn, so if I'm incorrect about ANYthing, please don't hesitate to correct me and let me know. I realize I'm human and can misunderstand what I read a lot.
EDIT: just finished attempting LXC inside UT, nope. fails initializing CGroup support, and libertine-container-manager claims "System kernel does not support lxc type containers. Please either use chroot or omit the -t option."
