I already have machine with up-to-date portsnap data and I want to update my newly fbsd machine with newest portsnap. Firstly I just scp files from my 'master' portsnap machine, after that i run portsnap extract, and error happens:
files/1be3201cdeeb1e1e2754f17d84d027f3e2d10750dc37e57cbdd950cd27b945d1.gz not found -- snapshot corrupt.
Don't worry, you no need start from beginning... Just download missing file, for example:
After fetching just trying to execute portsnap extract. Done.
