    1. Follow the same steps for Server 34 – 35?

      Anything different for a command-line only server?


      • This works directly with Fedora servers!

    2. A very helpful guide, as usual. Thanks.
      Upgraded 34 to 35, workstation.

      • You’re welcome! Nice to hear that works as expected!

    3. Hi,

      I have dual boot Fedora 34 with Windows 10. Is this safe to using this guide to upgrade in my environment?

      Last time upgrade from Fedora 33 to 34 in dual boot mode was broken. After reboot, grub was missing and directly boot from Windows.


      • Hi,

        I have tested this one PC with Fedora 34 and Windows 10, no problems. You can always reinstall Grub, if some reason it’s missing. You can also check your PC boot menu / UEFI boot order, just change Fedora before Windows and it should work again.

    4. I found the upgrade process to be straightforward and easy. Fedora 35 has not caused any new anomalies. Thanks for providing these easy steps.

      • Excellent! You’re welcome!

    5. The dnf upgrade download portion went off without a “hitch”. But then the reboot hung and did nothing for an hour. Seeing no drive activity I tried the Power Down Power Up approach, which resulted in a flawless upgrade.

      • Hello Robert,

        Excellent to hear that everything worked after power down and power up!

    6. I attempted an upgrade from Fedora 33 to Fedora 35. After the transaction check, I got the error message:

      Error: Transaction test error:
      file /usr/share/proj/proj.db conflicts between attempted installs of proj-8.2.0-1.fc35.i686 and proj-8.2.0-1.fc35.x86_64

      Hoping that the package ‘proj’ may not be too important, I tried the command:
      $ dnf remove proj
      There are over 100 packages that would be removed, so I left it intact.

      Any ideas as to the meaning of this error message, and what I should do about it.

      Thank you.

      • Hello Tom,

        Sorry for the late reply, do you have some 32-bit software installed on your system?

        This conflict is between proj-8.2.0-1 i686 and x86_64 versions. Both try to use/install same file /usr/share/proj/proj.db.

        Actually this might be even bug, if both should be possible install same time.

        • I had skype- installed, which caused a bunch of i686 packages to be installed, which caused proj-6.3.2-5.fc33.i686 to be installed. Removing skype seems to have removed all of the problem packages.

          Transaction check now passes.
