On this Forum, it was asked:
Whenever I sudo apt install an app, it's first checked if it exists in Neon's repo. If it does, it gets installed from there. If the app is not present in Neon's repo, then it's pulled in from Ubuntu's repo. Is that correct? Short answer: YES! But it's not a question of (non-)existence alone. There are rules of priority within the package management configuration. The details: An example $ aptitude versions '?name(plasma-workspace$)?origin(neon)' Package plasma-workspace: p A 4:5.10.0-0neon+16.04+xenial+build84 xenial p A 4:5.10.1-0neon+16.04+xenial+build85 xenial p A 4:5.10.2-0neon+16.04+xenial+build86 xenial i A 4:5.10.3-0neon+16.04+xenial+build87 xenial <== newest==preferred $ aptitude versions '?name(plasma-workspace$)?origin(Ubuntu)' Package plasma-workspace: p A 4:5.5.5.2-0ubuntu1 xenial Package plasma-workspace:i386: p 4:5.5.5.2-0ubuntu1 xenial # The newest version is preferred. Origin (Ubuntu or Neon) is irrelevant. # So far it's the normal mechanism: Newer is preferred. # And also: There are other priorities set to give Neon the advantage. # End of Text |

# If someone is interested in finding the
# possible 'origin'-values, # here's how to find out: $ dpkg-vendor --query 'Vendor' <-->neon $ dpkg-vendor --query 'Parent' <-->Ubuntu $ apt-cache policy | grep -E -o 'o=[^,]+' | sort -u <-->o=Opera Software ASA <-->o=Oracle Corporation <-->o=TorProject <-->o=Ubuntu <-->o=Valve Software LLC <-->o=Vivaldi Technologies <-->o=neon Edit: Forgot '-E' after grep, because my 'grep' is an bash-alias… |

2 Blog-Posts at the top refer to:
$ lsb_release -sd; echo -e "\nwith most current updates at UTC-time:"; date -u KDE neon User Edition 5.10 with most current updates at UTC-time: 2017-07-20T12:45:28+0000 |

I'm not sure I wanna go that deep yet. I use KDE Neon. Hence my distribution is Ubuntu Xenial with some extras on it, namely KDE Neon (software repository). Also, I don't need much to be happy. Neon has already covered most of my needs. I prefer the following way, for the time being:
I interpret the above as follows: 1. No K3B in Neon's repo 2. No QupZilla in Neon's repo 3. Calligra is present in Neon's repo. Don't now if it's the latest version though. What do you think? If I download plain Xenial with Unity on it, and search for QupZilla and K3B, I'll find the same versions, I assume. Edit: I'm using Neon User LTS at the moment. Edit 2: Referring to Calligra's version present in Neon's repo. Seems it's the latest based on this
and that: https://www.calligra.org/get-calligra/

dev-unstable machine Above shows it clearer to me, if you know the packagename. 1. k3b in both 2. qupzilla only provided by the ubuntu repo 3. calligrawords in both All with priority of 500, so highest version number is the installation candidate in each case where more than one. |

@acheronuk Thanks. I've just learned something. which is good. My results:
For some reason, I prefer Calligra over Libre. Qt, I guess. That's why. But it's capable too.

@Packagers of Neon User LTS Please package a fresh K3B and a fresh Qupzilla.
 @acheronuk Can't thank you enough. A command to be remembered (by me and others like me, if they care):
The forum is actually useful.
