Thank you for posting that, for whatever reason I previously did not find any posts with information on where to obtain Crimson installers.
That said, I really am not excited about doing a clean installation because that would involve a tremendous amount of work and hassle getting everything reconfigured and dialed back in.
If anyone knows of a solution to the fwupd libflashrom1 dependency, or if fwupd is even necessary on a PureOS desktop install, please weigh in.
