[Buildbot-devel] Problem upgrading to 0.8.4p1

[Matthew Morse]

I used pip to upgrade the buildbot software on the machine that hosts our buildbot masters, restarted the machine, ran 'buildbot upgrade-master' on each master, but now they error out with:

Buildbot version: 0.8.4p1
Twisted version: 8.2.0

Any ideas why this happened, and how to fix it?

Thanks,
