Comment 11 for bug 1869819

Thanks for the bionic patch, please read https://packaging.ubuntu.com/html/fixing-a-bug.html for next time though and provide a proper debdiff

I'm fixing your changes and uploaded now, what was missing is
- only the patch to the upstream code should be in debian/patches, the changelog needs to be directly updates
- the patch should be listed in the serie
- the bug reference should be listed as 'lp: #...' in the changelog (especially important for a SRU since the bug is what ensure the testing process can be followed)
