That may be the point, because I have a 8.1 running happily in VirtualBox with working guest additions. You may want to update virtualbox, that may help.
I have the exact same error; value error ! What am I supposed to do?
Same here. New installation of RHEL 8.2, kernel 4.18.0-193, VBox 6.0.20.
Guest additions will not install with the exact messages as above.
Nir.
Just waiting for Vbox to catch up. No other option by the look of it.
I had that kind of problems with CentOS 8, but all works, you have that issue because you are using minimal installation, without standard set of packagesâŚso missing tar, bzip2, etc⌠Install these and it will work:
yum install kernel kernel-devel kernel-headers gcc make perl elfutils-libelf-devel bzip2 tar -y
Month later, latest versions from both VirtualBox 6.1.16 r140961 (Qt5.6.2) and CentOS-8.3.2011 still the same problems. Even straight booting a vm from the iso 8.3 does not work. Workaround by installing CentOS-8.2.2004, upgrading and rebooting in the 8.2 kernel.
Creating the vboxguest module and siblings for kernel 4.18.0-240.1.1.el8_3 results in âValueError: File context for /opt/VBoxGuestAdditions-6.1.16/other/mount.vboxsf already definedâ.
Hi @Jan_de_Haan
I was having the same problem as you above: âValueError: File context for /opt/VBoxGuestAdditions-6.1.16/other/mount.vboxsf already definedâ
Another page solved my issue with the following commands:
sudo dnf -y install gcc automake make kernel-headers dkms bzip2 libxcrypt-compat kernel-devel perl
sudo semanage fcontext -d /opt/VBoxGuestAdditions-/other/mount.vboxsf
sudo restorecon /opt/VBoxGuestAdditions-/other/mount.vboxsf
And then retry the installation
For reference, the post was from âtechnologytalesâ (I canât share the link here as a new user). I hope that helps.
