[xubuntu-users] upgrade Tunderbird, Lightning missing

[Dr. Heiko Pollmeier]

Gruß zuvor / Greetings first!

After I upgraded xubuntu from 16.04 LTS to 18.04 LTS there was
automatically also a new Version of thunderbird (60.2) installed.
 With this new version of thunderbird the calendar extension lightning
doesnt work anymore.
How can I go back to version 59.2 , where lightning does work?

Mit freundlichen Grüßen / With kind regards
