I have just upgraded from Thunderbird 15 to 16 and then found that Lightning 1.7 is not compatible with Thunderbird 16, leaving me without a calendar.

What are my options?

Should I try and go back to Thunderbird 15 or is there someway of finding a version of Lightning that is compatible with Thunderbird 16?

I need to have a working calender and have been happily using Lightning for many years.

I am using Ubuntu 12.04 (precise) 32-bit if that is any help


Lightning 1.8 has been uploaded

https://launchpad.net/~mozillateam/+archive/thunderbird-next Launchpad logo

ppa:mozillateam/thunderbird-next Launchpad logo (Click here for instructions on using PPAs.)

Lightning 1.8 should also be pushed out with Thunderbird 16 when it is released to the main archive (with the exception of 10.04 which will need to go to lucid-backports and might lag behind a day or 2)

  • why can't you add this from add-on's? – Thufir Oct 27 '12 at 2:40
  • addons are either 32 bit only or platform independent, lightning is an architecture specific addon which means that it can't properly be supported through addons.mozilla.org – micahg Nov 9 '12 at 17:38

You can try the Thunderbird Add-on 'Disable Add-on Compatibility Checks' to bypass this problem.

This is a workaround though, realize that once you do this you may introduce bugs with Thunderbird or your Add-ons.

It's a good idea to keep a backup of your Thunderbird profile to restore from if anything breaks or fails. Here's how.

  • Lightning is a binary addon, so the compatibility checks shouldn't make any difference – micahg Oct 5 '12 at 3:22
