I believe I have the same problem: an Ubuntu upgrade has caused the Ubuntu-installed gdata provider to not be visible in the Thunderbird addons list. This results in all of my google calendars being greyed out in the Thunderbird calendar pane.
xul-ext-gdata-provider's description states that it is a "transitional package", and it is not listed on the ubuntu package repository webpage. I am using the xul-ext-lightning package to enable the Calendar pane in Thunderbird. Installing "Provider for Google Calendar" from the Thunderbird addons menu has restored my ability to access my calendars. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1798090 Title: Xenial update of thunderbird seems to have broken lightning/gdata provider To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/thunderbird/+bug/1798090/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
