@thunderbird #thunderbird #linux

My TB data spans decades, for emails, tasks & events [oh, & also contacts]. I've lost count of however many TB iterations / versions it's lived thru. It began life yonks ago in Win7, & lives now, for many years, in Linux.

For at least a couple of years, my Calendar has had this damn annoying problem. For many Events, but not all, it is just impossible to directly duplicate them. Both Ctrl-C Ctrl-V, & RMB-Copy RMB-Paste, simply do NOTHING [for it seems like the majority (but not entirety) of my Events].

Research lead me to https://bugzilla.redhat.com/show_bug.cgi?id=2015334 [my distro is #Arch not #Fedora, but IMO that's irrelevant]. I was galled to see that bug report was closed without action or solution; also that it was raised only with Redhat not actually Thunderbird.

In exasperation, recently i conceived this inefficient albeit effective workaround: for the target Event, RMB-ConvertTo-Task, then edit said new task to desired date for the intended duplicate, then convert said task to a new Event... then correct all the text formatting that was buggered by this silly indirect process.

I've wondered if possibly the database has become corrupted somehow due to surviving all the historical TB version changes, to cause this duplication problem. So last night i thought i'd Export the Tasks & Events ICS file, then Import it into a clean TB profile elsewhere [in some vague hope that this process might magically "fix" any putative data corruption; hahahaha yeah right]. The Export nominally succeeded, being an 81 MB file. The Import failed every time, with the error msg per pic.

What is a frustrated user now supposed to do? 🤷‍♀️
