Pip pprint 404 error when updating

Troubleshooting
1

I’m getting the following error when running brewbox-ctl update. That url doesn’t seem to exist, the closest I can find is https://pypi.org/simple/buck-pprint/.

Collecting pprint<0.2,>=0.1 (from brewblox-ctl)
Exception:

It looks like somebody took the package offline sometime yesterday.
I just pushed a quick fix. If you re-run brewblox-ctl update, it should now install brewblox-ctl 0.21.8.

I started a new fermentation without updating. Any reason to wait until it’s done to test the hotfix, Or are you pretty confident it should work or at least fail safe?

4

That’d depend on when you last updated.

If the timing matters: we expect the next release in ~2 weeks.

Firmware version - 27d2a967 (2020-05-13)

I’ve realized that I don’t know how to find the brewblox release version. brewblox-ctl env list doesn’t seem to do the trick. The bug reporting menu in the UI says build date: 2020-06-02T16:34:22.936Z but that doesn’t seem to correspond with any of the release dates from the change logs.

The UI / firmware release dates are pretty good indicators. A UI build date between releases means you have a hotfix build for the UI.

The big changes are that we migrated the eventbus protocol, and rewrote some OneWire firmware code.

The eventbus change is relevant if you were using a Tilt/iSpindel service, and the OneWire change fixed some hangups in DS2413 extension boards.

Unless you’re making extensive use of extension boards, there is no pressing reason to upgrade in the middle of an active fermentation.
