If you do not have your web interface and script in /var/www/ and /home/brewpi, the updater will ask you where it can find it.
If the updater does not work well, you can still do a git pull in each directory manually:
git checkout master
git pull
After that, run this in each script dir:
bash utils/runAfterUpdate.sh
Update your Arduino with:
python util/updateFirmware.py
Please make a backup of all directories first.
Allrighty! Now just contact my friend who knows more from IT and let him install this new version.
Awesome work guys!! Can’t wait to get back from work now!
So, just to confirm, if I am currently on the development branch do I just simply run the commands in the first post above, or do I need to manually switch back to master before updating? If I need to manually switch back, how do I do this?
Thanks again @Elco
The updater will ask you if you want to get back on the master branch.
Perhaps just being stupid, but after updating how do I switch out of testing mode?
Glad you asked, I’m sure there are others wondering the same thing! 
In the web UI, select the mode, like off, fridge constant, beer constant, beer profile. This will change the mode away from “test”.
To go back to test mode, select the “Advanced Settings” tab and select the desired mode with the “mode” drop-down.
I moved 10 posts to a new topic: Updating manually (because I’m running multiple instances of BrewPi on one pi)
Thanks - worked great! I had to switch it to ‘off’ first - if you switch it to beer constant or fridge constant it says invalid mode and it remains in test mode.
Hello there,
I’m having a bit of trouble, and I don’t know what to do, any help would be greatly appreciated. This is what I see when I try to update the firmware. Also, when I try to update it on the web host, I get an error telling me I didn’t specify the board, even though I did say it was the Spark Core.
Thanks,
pi@raspberrypi ~/brewpi-tools $ sudo python updater.py

Hi guys,
I have some troubles to update to 0.2.8 but the error seems to be different than @kekich one. I tried several times with the python script (using the web interface leads to the same issue)
The error is
Problem flashing file: 87
Can’t figure out what this means. Could you please help?
The full console output is reported here below:
sudo python updater.py

During the flashing, the core is running a process from Spark’s framework to receive the new firmware. This protocol is not always reliable, but usually works on retry. It also seems to be more reliable on Windows than on linux/osx. We are going to try to change the protocol, it does not only affect BrewPi, but all Spark Core users.
In the meantime you could try programming in Dfu mode if it keeps failing.
I can connect to the internet, and I can ping google.com, yahoo.com, and github.com without any issue.
The url it is trying to read is https://api.github.com/repos/BrewPi/firmware/releases
I wonder why it doesn’t work.
My update went ok until it tried to check firmware version.

It updated the firmware after I ran it again selecting No to update the firmaware and then running it again and selecting yes. So the 3rd time was the charm. 
Update: Lost all of my settings on the update.
Looks great guys, Super easy to upgrade. Way to go, I know you have been swamped.
All looks good here - had the same error as above:

Checked DNS was resolving successfully, which it was, re-ran the script, and it went through fine. Successfully backed up and restored current settings as well.
Cheers,

The reason for the error is as follows:
That is why it works on second try. Will be fixed shortly 
Programming using dfu-utils worked.
Thanks for the advice
