[Resolved] VirtualBox 6.0 will not install due to missing Python(abi)

[bgee22]

I am trying to install VirtualBox-6.0-6.0.14 on a Fedora 31 computer. DNF issues an error message that no provider for python(abi) can be found. This problem started while the computer had Fedora 30 on it.

Code: Select all

Problem: cannot install the best update candidate for package VirtualBox-6.0-6.0.10_132072_fedora26-1.x86_64
  - nothing provides python(abi) = 3.6 needed by VirtualBox-6.0-6.0.14_133895_fedora26-1.x86_64

The computer has 6.0.10 installed but it will no longer run. It worked as recently as about August of this year. The kernel module will not load. When I try to rebuild the kernel module, it throws other errors:

[root@laptop2 ~]# /sbin/vboxconfig
vboxdrv.sh: Stopping VirtualBox services.
vboxdrv.sh: Starting VirtualBox services.
vboxdrv.sh: Building VirtualBox kernel modules.
vboxdrv.sh: failed: Look at /var/log/vbox-setup.log to find out what went wrong.

There were problems setting up VirtualBox.  To re-start the set-up process, run
  /sbin/vboxconfig
as root.  If your system is using EFI Secure Boot you may need to sign the
kernel modules (vboxdrv, vboxnetflt, vboxnetadp, vboxpci) before you can load
them. Please see your Linux system's documentation for more information.

The last few lines of /var/log/vbox-setup.log look like this:

What's going on? What can I do to get VirtualBox installed on this computer?

Something seems to be wrong with your VirtualBox repository setup.
Using the repo file from https://www.virtualbox.org/wiki/Linux_Downloads should give you the "fedora29" builds on Fedora 31, not the older "fedora26" builds.

Hi Martin -

Wow, good catch! That was exactly the problem. For reasons I do not remember, I had modified the repo file to specify "/28/x86_64" instead of "/$releasever/$basearch". Switching it back made everything work.

Thjanks!

I had a similar "problem" some weeks ago after updating to Fedora 30.
My repo file did specify the version 26, probably from the time I updated to Fedora 27.
