Thunderbird Ligthning gone after update

Hi - after updating MozillaThunderbird from the Update- Repo to Version 68.4.1 of 2020-01-10 again the Calendar has gone.

For me, this is due to delivering some Value in the Configuration for “extensions.installedDistroAddon.{e2fda1a4-762b-4020-b5ad-a41df1933103}” with the new patch(?)
Here is how to get it to work again: https://support.mozilla.org/en-US/kb/calendar-updates-issues-thunderbird#w_lightning-disappears-after-a-thunderbird-update-release-and-beta-versions

If this happens to all other users too: This is quite Complicated for some newbies - and i already had to do it many times (when Updating the Version).

Does anyone else have also the same behaviour?

If yes: PLEASE any Maintainer of this Package: The Calendar is not an Addon any more (since years), it is included in Thunderbird. Can you please check to change the Config-Value in the Future to not have any value, so the Calendar works after update?

I’ve never experienced that problem. (Using Thunderbird from the “Mozilla” repository https://download.opensuse.org/repositories/mozilla/openSUSE_Leap_15.1/ )

If you feel this is a valid bug then raise an issue on the openSUSE bugzilla: https://bugzilla.opensuse.org (same login credentials as the forum).

Try this (it’s worked for me before)

Lightning disappears after a Thunderbird update (release and beta versions)

This may happen if the update of the add-on is stuck. Don’t worry about your calendar data, it is left untouched and will be available again if you follow these steps to restore Lightning:

  1. Go to the Advanced section of Thunderbird Preferences and click on Config Editor…
  2. Copy or start typing extensions.installedDistroAddon.{e2fda1a4-762b-4020-b5ad-a41df1933103} into the search box
  3. When extensions.installedDistroAddon… is listed in the preferences list, right-click on it and choose Reset from the context menu - the preference now isn’t bold anymore and its value is empty
  4. Close the editor, leave the Thunderbird options, open Thunderbird’s add-ons manager and switch to the list of installed extensions
  5. If Lightning is listed there, click on Remove to the right of the list item
  6. Restart Thunderbird
