Ubuntu 16.04 LTS has the latest Evolution 3.18 release. It's generally against Ubuntu's SRU policy to allow new major versions (3.18 > 3.20) into a stable release.
https://wiki.ubuntu.com/StableReleaseUpdates If you need a newer version of Evolution, I encourage you to consider upgrading to Ubuntu 17.10. Ubuntu 17.10 is not a LTS so you will need to upgrade to 18.04 LTS in 6-9 months. But Ubuntu 17.10 does have Evolution 3.26.1. ** Changed in: evolution (Ubuntu) Status: New => Invalid -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1728679 Title: upgrade-software-version for Xenial To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/evolution/+bug/1728679/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
