Trouble installing VirtualBox guest additions on Centos 8
by Felthorn3 from LinuxQuestions.org on (#5930Q)
Just to preface: I'm pretty new to VirtualBox and Linux, so please bare with me. I just downloaded the CentOS 8 DVD ISO image, installed it on a VM in VirtualBox and it appears to function correctly, minus the guest additions which is supposed to fix mouse/screen issues(?). In the terminal window I have executed the following commands:
sudo yum install gcc
sudo yum install make perl
sudo yum install kernel-devel
sudo yum install elfutils-libelf-devel
All of these appear to have completed successfully, and I then attempt to install guest additions and I see the following in the attached image at https://ibb.co/JsnW1ZD. This was my second attempt to install the additions which is why I believe it's saying it's removing the installed version of them. The first time I attempted the same basic errors/information was generated. I've been fighting with this for a good while now and am pretty frustrated. I just want my VM to work so I can learn the OS, and this is super discouraging. I have also attempted to just remove the VM and install again from fresh and end up with the same result.
Thanks for any help you guys can provide.
