Hope this is a good place for this. Mozilla's support forum... leaves much to be desired. So I thought I'd ask here first.
So I finally bit the bullet and installed Ubuntu 10.10 as my primary OS. I am having trouble with Mozilla Thunderbird's add-on Lightning (calendar), and I am presently unable to retrieve my calendar that I RELY on! Unless of course I spend an hour reversing the hardware changes I made and get my Windows hard disk back in this computer (it's a very tight case, and my Win hd is in an external enclosure now) and pass on Ubuntu.
I had no problem installing Thunderbird 3.1 and migrating my profile and emails. But the calendar showed up blank and was not functioning properly. So I uninstalled it and tried reinstalling it a few times, to no avail. I downloaded the Lightning .xpi add-on file from Mozilla's own add-on site, clicked Install as instructed in Thunderbird's add-on manager, but I get this message every time:
"Lightning" could not be installed because it is not compatible with your Thunderbird build type (Linux_x86_64-gcc3). Please contact the author of this item about the problem.
I noticed on Mozilla's Lightning Project Home site, while x64 is not specifically mentioned as being incompatible, Linux x86 is specifically mentioned (not x64) as being supported. And I did install the x64 version of Ubuntu.
I also found on Lightning's system requirements page that there are several packages that are needed for Lightning to work. I ran Synaptic Package Manager and only found one of the five mentioned packages even listed, libstdc++5. It was not checked on, so I installed it with Thunderbird closed, restarted it and tried installing Lightning again to no avail.
I am still very new to Ubuntu, and do not even know how to reliably find these other packages, let alone know if it is even a) advisable for my particular Linux version (Ubuntu 10.10) or b) worthwhile to try since I am wondering if x64 is simply not supported? Anybody know about this, and what I can try? Otherwise, I'll have to try to figure out why I can't get VirtualBox to work properly with my Windows CDs (another story, for another day). Thanks!
