I went through everything I could find, did a fresh install on a Nexus 5, it did hang at 90% (didn't see the thread on using a different recovery until too late, used twrrp). I left for awhile, then re-booted. It loaded fine, with working wifi...

Since it did hang at 90, does that mean it failed to finish installing something? I drop into term and everything seems to be there and working. I would just hate a surprise to pop up when I needed something.

Haven't plugged in external wifi yet, but will check that in a bit.

I've also seen a few threads about not running the regular apt update/upgrade, should I steer clear of that?

Thanks.
