Since the upgrade of Lightning 2.6.0 to Lightning 2.6.1, this extension need Thunderbird 24.0.1 but Ubuntu only give Thunderbird 24.0.0

"Update 4: Lightning 2.6.1 is now public. On Linux, it is compatible ONLY with Thunderbird 24.0.1, so go ahead and upgrade now."

A lot of people don't use the Ubuntu package for Lightning but those of Mozilla.

Ubuntu should give an upgrade to Thunderbird 24.0.1 and Lightning 2.6.1
