Description of problem: Can't upgrade to Fedora 27: xmvn-launcher can't be found/installed. I'm trying to upgrade from a working Fedora 26 to Fedora 27 following instructions on this page: https://fedoraproject.org/wiki/DNF_system_upgrade Version-Release number of selected component (if applicable): xmvn-launcher-2.5.0-21.fc26.noarch (?) aether-ant-tasks-1:1.0.1-6.fc26.noarch (?) How reproducible: Use "sudo dnf system-upgrade download --refresh --releasever=27" - fails every time. see below. Steps to Reproduce: sudo dnf system-upgrade download --refresh --releasever=27 Actual results: [this-user: ~]$ sudo dnf upgrade --refresh (also tried "dnf --refresh upgrade" per below; same result) [sudo] password for this-user: Last metadata expiration check: 0:00:00 ago on Tue Nov 21 15:22:19 2017. Dependencies resolved. Nothing to do. Complete! [this-user: ~]$ sudo dnf system-upgrade download --refresh --releasever=27 Before you continue ensure that your system is fully upgraded by running "dnf --refresh upgrade". Do you want to continue [y/N]: y Last metadata expiration check: 0:00:00 ago on Tue Nov 21 15:22:59 2017. Error: Problem: package aether-ant-tasks-1:1.0.1-6.fc26.noarch requires xmvn-launcher, but none of the providers can be installed - xmvn-launcher-2.5.0-21.fc26.noarch does not belong to a distupgrade repository - problem with installed package aether-ant-tasks-1:1.0.1-6.fc26.noarch [this-user: ~]$
I just saw this: If some of your packages have unsatisfied dependencies, the upgrade will refuse to continue until you run it again with an extra --allowerasing option. Using --allowerasing seems to have fixed this installation issue.
Hmm, I thought we retired aether-ant-tasks. Either way, aether-ant-tasks obsolete so I would recommend uninstalling it before attempting to upgrade to F27.
aether-ant-tasks is indeed retired from f27 on, but nothing Obsoletes it (in RPM sense). I think we should add Obsoletes either to fedora-obsolete-packages or maybe ant
