I may be teaching you to suck eggs but I run Thunderbird 2, Lightning 0.9 and Provider for Google calendar .0.5.1 and it works perfectly.
Looking back over the emails you seem to be trying to download a program whereas Lightning and Provider for Google calendar are addons. They are available by going to https://addons.mozilla.org/en-US/sunbird/addon/4631 for the Provider. (It says it is for Sunbird but it works with Thunderbird.) and These Release Notes cover what's new, download and installation instructions and known issues for Lightning 0.9 Please read these notes and the bug filing instructions before reporting any bugs to Bugzilla. What's New in Lightning 0.9 Lightning 0.9 is the latest release of our calendar extension for Mozilla Thunderbird®. We recommend that all users upgrade to this latest version. The following features have been added to Lightning 0.9: * Events spanning days now have a visual indicator indicating them as connected events * When reloading a remote calendar a progress indicator is now shown * The so-called "minimonth" (small calendar month in the upper left) has been given a visual overhaul * The calendar views (day, week, multiweek, month) have been given a visual overhaul * The today pane can now be displayed in calendar mode and task mode as well * CalDAV support and interoperability with various CalDAV servers has been improved * iMip/iTip support (support for email invitations) has been greatly improved * The application stability and memory consumption has been greatly improved * Lightning 0.9 is intended to be the last release for the Thunderbird 2 series. For the future we are planning to integrate Lightning fully into the upcoming Thunderbird 3 release * A full list of changes that have gone into this release can be found on The Rumbling Edge website Release Date: September 23, 2008 Downloading and Installing Downloading Lightning 0.9 Before installing, make sure your computer meets the system requirements. Mozilla.org provides Lightning for Windows, Linux, Solaris, and Mac OS X in a variety of languages. Windows users must have Windows XP or later. IMPORTANT: Install the updated timezones for Windows XP or later. Information on obtaining the updated timezones can be found in Microsoft Knowledge Base article 951072. Not updating your Windows timezones will result in unreliable and erroneous display and entry of time data! Be sure to do this! Windows releases prior to Windows XP are working but may display event times erroneously due to outdated timezones on the operating system level. This can be fixed using unofficial patches. Users should read the known issues section for more information. To get Lightning 0.9, download it from http://www.mozilla.org/projects/calendar/lightning/download.html Installing Lightning Lightning runs as an extension for Mozilla Thunderbird 2.0.0.x IMPORTANT: If you have been using the old Calendar Extension, be sure to backup the ICS file that it put in your profile directory, and uninstall the Calendar Extension before installing Lightning. After you have installed Lightning, you can then import your old events and tasks from the backed up ICS file. 1. Right-click the download link and choose "Save Link As..." to download and save the .XPI file to your your hard disk 2. In Mozilla Thunderbird, under the "Tools" menu, open the "Add-ons Manager" 3. Click the "Install" button, locate and select the .XPI file you downloaded in step 1, and click "OK" 4. Restart Mozilla Thunderbird In Google choose settings, calendars,private address, copy the XML link In Thunderbird Select Calendar, New Calendar, On the network, Goolge Calendar, and paste the location from Google and all should be OK. A better description is given at http://bfish.xaedalus.net/?p=239 but a search on the same site says Stevo 4:57pm August 26th 2008 | 4:57 pm For those on Ubuntu 8.04 (Hardy) AND are getting the problem with File / New… / Calendar being greyed out (even after clicking the Calendar icon in the lower left of TB)…. This fixed is for me: http://blogs.sun.com/beuchelt/entry/thunderbird_lightning_and_the_ubuntu Using the Synaptic Package Manager, I searched for libstdc and marked the version 5 for install and installed. Uninstalled both Lightning and Google iCal addons and closed / reopened TB and followed the above EXCELLENT install howto - and voila… now working. Which solved a problem I had. It may have been updated in the latest versions but it's worth a thought. Gerry -- ubuntu-uk@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-uk https://wiki.ubuntu.com/UKTeam/
