I noticed Gwibber, my social networking app for Ubuntu, stopped updating my Twitter status after the API was updated. Basically, it was broken.
And as of yet, it’s not been patched.
Here’s a fix I used to get Ubuntu updating my Twitter account again.
pkill gwibber sudo gedit "/usr/share/gwibber/plugins/twitter/__init__.py"
Then search and replace “api.twitter.com/1” to “api.twitter.com/1.1”
For the sake of honesty, I’ll admit I didn’t find this fix myself, I found it here.
