DNF System Upgrade fails to upgrade to Fedora 27. The logs say this: zář 18 11:25:45 xps13-jeischma systemd[1]: Rebooting: service failed zář 18 11:25:45 xps13-jeischma systemd[1]: dnf-system-upgrade.service: Failed with result 'exit-code'. zář 18 11:25:45 xps13-jeischma systemd[1]: dnf-system-upgrade.service: Unit entered failed state. zář 18 11:25:45 xps13-jeischma audit[1]: SERVICE_START pid=1 uid=0 auid=4294967295 ses=4294967295 subj=system_u:system_r:init_t:s0 msg='unit=dnf-system-upgrade comm="systemd" exe="/usr/lib/systemd/systemd" hostnam zář 18 11:25:45 xps13-jeischma systemd[1]: Failed to start System Upgrade using DNF. zář 18 11:25:45 xps13-jeischma systemd[1]: dnf-system-upgrade.service: Main process exited, code=exited, status=1/FAILURE zář 18 11:25:45 xps13-jeischma dnf[966]: Chyba: žádný balíček není vhodný The last line says: Error: no package is suitable. I've been able to reproduce this on two different machines. I had to run 'dnf system-upgrade download --refresh --releasever=27' with updates-testing enabled to bypass the issue with grub2. Otherwise nothing special, my F26 machine is up-to-date.
