The only Fedora 29 specific instructions that I found are at this link: https://www.if-not-true-then-false.com/2010/install-virtualbox-guest-additions-on-fedora-centos-red-hat-rhel/

Since that link is apparently focused on guest additions, I decided to ignore it.

A year ago, I successfully installed VirtualBox in Fedora 26 by following instructions that were similar to the following link: https://www.if-not-true-then-false.com/2010/install-virtualbox-with-yum-on-fedora-centos-red-hat-rhel/

Since I couldn't find corresponding instructions specifically for Fedora 29, I attempted to follow the same instructions. First, I executed the following command:

dnf install binutils gcc make patch libgomp glibc-headers glibc-devel kernel-headers kernel-devel dkms

Although the command appeared to complete normally, it did show the following message:

Failed to synchronize cache for repo 'virtualbox', ignoring this repo.

I then executed:

dnf install VirtualBox-5.2


Fedora 29 - x86_64 - VirtualBox                                               
Failed to synchronize cache for repo 'virtualbox', ignoring this repo.
Last metadata expiration check: 0:05:45 ago on Sat 17 Nov 2018 03:40:42 PM PST.
No match for argument: VirtualBox-5.2
Error: Unable to find a match

I am not sure if this is relevant, but just out of curiosity, I executed

cd /
find -type f -iname "virtualbox.*"
find -type f -iname "virtualbox*" 



It seems as if Fedora 29 (complete install, not upgrade) is installing some VirtualBox Guest-Addition rpm's. I will post a separate query re what I should do to install guest additions once I've got VirtualBox installed. I mention it in this posting only as it might relate to my specific problem.

Similarly, I'm unsure whether the following link is relevant: VirtualBox failed to install in Fedora 26

In that link, I made a mistake and got UnixSE responses about backing out my mistake before I did the install.


  1. Why am I getting the message "Failed to synchronize cache for repo virtualbox"?

  2. Why am I getting the message "No match for argument: VirtualBox-5.2"?

  3. Do I need to back anything out before I proceed with the install?

  4. How do I install VirtualBox in Fedora 29.

Looking at the raw repo at http://download.virtualbox.org/virtualbox/rpm/fedora/ they don't seem to support 29 yet, only up to F28. You should be able to edit the repo file and change $releasever to 28 and then dnf install VirtualBox-5.2 .

  • @AaronDMarasco Aaron, thanks for the analysis. Your approached worked but revealed an underlying problem. When I re-attempted dnf install VirtualBox-5.2, I got several error messages similar to Problem: conflicting requests - nothing provides libvpx.so.4()(64bit) needed by VirtualBox-5.2-5.2.0_118431_fedora26-1.x86_64. I will wait a couple of months and then re-try. It looks like your analysis answered my question 2. I also welcome an answer for question 1. Nov 18, 2018 at 1:14
  • Question 1 is because download.virtualbox.org/virtualbox/rpm/fedora/29 is not a valid URL; it doesn't exist on the repo site. download.virtualbox.org/virtualbox/rpm/fedora/28 is where I indicated you should point to. Some sources for your missing library can be found at rpmfind.net/linux/rpm2html/… Nov 18, 2018 at 1:24
  • @AaronDMarasco Aaron, thanks again. For others: Following Aaron's original answer, my re-try did in fact point to ../rpm/fedora/28, which is why the re-try got different errors. I suspect that it will be cleaner simply to wait a few months and then re-try. Nov 18, 2018 at 3:04
