      • Hello Luciano,

        Did you get any errors when you downloaded packages?

    3. a) Package yumex-dnf causes a conflict when you start command:
      dnf system-upgrade download –releasever=27

      Error message would say that there is a conflict between dnf-dragora-gui from F27 & 26 & between yumex-dnf.

      Solution is removing yumex-dnf, cleaning dnf cache rebuilding it (dnf clean all, dnf makecache). Then try again and you will suceed.

      Writing this after successful update, of course.


      2.4 Install/Update dnf-plugin-system-upgrade package.

      It’s installed inside common plugins – at the time I checked dnf-plugins-core-2.1.5-4.fc27.src.rpm.

      And finally, mostly I update the system when the beta for next version is announced and the next Rawhide is out, so I get stable version on it. BTW, I do not rely only on classic Fedora repos – I mean Fedora compatible, but choose for yourself.
      Those procedures work pretty fine with them and I use them for years.

      Cheers, Jože

    4. Seems to work for FC 28 also. Just downloaded packages and verified install, heading onto reboot.

      Previous update worked out of the box.

      Cheers, Jože
