[Bug 1800147] Re: Bionic freeplane SRU [was: freeplane didn't show interface]

[Simon Quigley]

The bug title doesn't have to say SRU, and the SRU template should go
into the bug description. :)

The upload should also be versioned 6.1.1-2ubuntu0.1 (see
https://wiki.ubuntu.com/SecurityTeam/UpdatePreparation#Update_the_packaging
) and the upload should be targeted at bionic (except for backports and
security).

That being said, sponsored. Thank you for your contribution to Ubuntu!

+ 
+  * libknopflerfish-osgi-framework-java 6.1.1-2 does not set source and
