I use LinuMint 17.3 Cinnamon 2.8.8 (64-bit) with 3.19.0-32-generic kernel.
Yesterday I upgraded my version of Thunderbird to the 60.2.1 (64-bit). It came automatically with LinuxMint update manager, which I usually trust, so did yesterday. Unfortunately I find out that Lighting extension, with all my calendar data, just disappeared. I followed the suggestions here (https://support.mozilla.org/en-US/kb/calendar-updates-issues-thunderbird) but I turned out that is not possible to restore Lighting in my case. If I try to re-install it, it simply says the current Lighting version is not available for the latest Thunderbird one.
I backed up all my profile data and .thunderbird folder, so I hope to be able to find a way to fix this somewhere in the future.
I tried to downgrade Thunderbird, but it seems not possible to me to download a previous version from this website, neither I find it on my MintInstall manager. Any suggestion for this would be of great help. Also, if there is a Lighting version coming up anytime soon I'd be relieved of knowing that.
In the meanwhile, I would also appreciate if you can tell me a way to at least read my calendar from the .sqlite files in claendar-data folder. Maybe there's an alternative software I can use for this purpose? I tried also SeaMonkey, but it seems incompatible with a lot of stuff on my computer and it simply does not run when launched).
I am kind of desperate. Any suggestion is a big help. Alf
