I wrongly merged a patch that contained a huge file (i.e. 22 MB) and to avoid the pain of having people download a 20 MB git repository I have had to rewrite the git history to exclude that file. Anybody that has cloned or pulled after commit 15c33719cf6dfea1b4482a9436d83820d0dfbf88 (yesterday) should clone a fresh copy of ooni-probe. Sorry for the inconvenience. - Art.
