I'm running Vivid + Stable overlay PPA. For me, though, the really
interesting part is that even using the Android SDK tools manually is
unreliable:

$ fastboot flash recovery ~/Downloads/recovery-arale.img
ERROR: usb_read failed with status e00002ed
ERROR: usb_read failed with status e000404f
sending 'recovery' (10672 KB)...
ERROR: usb_read failed with status e000404f
FAILED (status read failed (No such file or directory))
finished. total time: 0.000s

If I can't reliably push things using fastboot, that rules out anything
specific to Ubuntu on the device.

And because this only started a month or so ago, it makes me think that
some sort of low level firmware type upgrade was flashed. I don't even know
if we do that sort of thing, but it's definitely what it feels like.
