Mea culpa, this is my fault. "ValueError: min() arg is an empty sequence" suggests that no uptake monitoring value could be determined. The issue is unrelated to the actual uptake monitoring or the partial versions but instead is related to the platforms parameter passed down via buildbot. Based on the intersection between the buildprops platforms and the local platforms from the mozharness configs, certain uptake checks are performed (http://hg.mozilla.org/mozilla-central/file/tip/testing/mozharness/scripts/release/uptake_monitoring.py#l132) In bug 1278312 we fixed the uptake monitoring in graph2 and turned it on starting 48.0b5. So, in 48.0b4 the buildprops platforms looked like this (via http://archive.mozilla.org/pub/firefox/tinderbox-builds/mozilla-beta-noarch/release-mozilla-beta-firefox_uptake_monitoring-bm70-build1-build0.txt.gz): --- 02:22:03 INFO - 'platforms': (u'linux', u'linux64', u'macosx64', u'win32', u'win64'), --- while in 48.0b5 the buildprops platforms looks like this (via http://archive.mozilla.org/pub/firefox/tinderbox-builds/mozilla-beta-noarch/release-mozilla-beta-firefox_uptake_monitoring-bm72-build1-build3.txt.gz): --- 22:40:10 INFO - 'platforms': (u"('linux'", 22:40:10 INFO - u"'linux64'", 22:40:10 INFO - u"'win32'", 22:40:10 INFO - u"'win64'", 22:40:10 INFO - u"'macosx64')"), --- It got messed up by this line from my commit https://github.com/mozilla/releasetasks/pull/181/files#diff-70163ba31e82fd96586fb6765ed90914L38 Because of it, no platform intersection could be determined in the uptake monitoring reckon, hence the empty sequence. Will push a fix in a bit.

Merged https://github.com/mozilla/releasetasks/commit/f3dc5cac0ddb930941358abfb150ddde07415644. Will leave this open till next beta, 48.0b6, confirms it's working just fine.

48.0b6 worked as expected \o/ See: * http://archive.mozilla.org/pub/firefox/tinderbox-builds/mozilla-beta-noarch/release-mozilla-beta-firefox_uptake_monitoring-bm72-build1-build9.txt.gz * https://tools.taskcluster.net/task-graph-inspector/#Z2BNOjUqTC-P6du___P5oA/ERZN22ZMQxaNfvQsXluIZw/0
