Guest Additions is not installing on CentOS7.8 x86_64 for VirtualBox
 

Not able to install Guest Additions 6.1.8 on CentOS7.8 (x86_65) with kernel version 3.10.0-1127.10.1.el7.x86_64. This is VirtualBox 6.1 on a Windows 10 host.

I'm using the following URLs to help with the install

There is no error output, seems like it installed ok. Reboot the VM and the screen remains the same.

The only logs that appear under /var/log/messages are vboxadd-install.log and vboxadd-setup.log. Neither of these have any odd output.

The only odd thing is that under /usr/src/kernels/3.10.0-1127.10.1.el7.x86_64, there isn't a build directory. I created that directory (is it supposed to be a directory or file, I'm not sure?). However Guest Additions was not successful.

thanks

Guest Additions for CentOS are provided by the RPM Fusion repository. They even have a howto for it. Despite it saying they only have packages for Fedora, last time I checked there were packages for CentOS, too. Don't forget to uninstall "official" Guest Additions first, before installing the package from RPM Fusion:
