Hi, as you can see at https://packages.ubuntu.com/bionic/evolution is from the "universe" repository. The same applies to Gnome, https://packages.ubuntu.com/bionic/gnome , an important hard dependency of libevolution https://packages.ubuntu.com/bionic/libevolution is libgnome-desktop-3-12 https://packages.ubuntu.com/bionic/libgnome-desktop-3-12 .
The policy to split software from upstream into tons of packages doesn't help either to grant stability. A short explanation of the "main" and the "universe" repository: "Main The main component contains applications that are free software, can be freely redistributed and are fully supported by the Ubuntu team." - https://help.ubuntu.com/community/Repositories#Main "Universe The universe component is a snapshot of the free, open-source, and Linux world. It houses almost every piece of open-source software, all built from a range of public sources. Canonical does not provide a guarantee of regular security updates for software in the universe component, but will provide these where they are made available by the community. Users should understand the risk inherent in using these packages." - https://help.ubuntu.com/community/Repositories#Universe Release date of Bionic Beaver Ubuntu 18.04 LTS is in April 2018, see https://wiki.ubuntu.com/Releases . Did you already ask why the new default DE is still from "universe"? The appropriate mailing list to do this is https://lists.ubuntu.com/mailman/listinfo/ubuntu-devel-discuss (don't confuse it with https://lists.ubuntu.com/mailman/listinfo/ubuntu-devel ). This should explain the issue with the Ubuntu policy and their unstable Evolution packages from the official Ubuntu repository. A lot of software provided by "universe" is stable, so why isn't Evolution stable, too? The answer is very simple, it's related to the dependency chain of the software. The longer the dependency chain, the harder it's to maintain a package. The Evolution coders can't change Ubuntu's policy, they just provide the source code with all the information needed to build Evolution from source.
