[Cbc] [External] Re: 2.10 version on Ubuntu

Fri Sep 13 19:03:28 EDT 2019

It worked fine for me from a fresh checkout. I think things may have gotten
corrupted if you updated your version of coinbrew and/or fetched the
release after previously fetching master first. Can you try just starting
from scratch? Once things stabilize, you should be able to switch versions
"in place" without issues.
