Search engine turns up loads of reports of this error message when installing guest additions to an application. I read about 50 of them, and tried some, but none of them made any difference. Here's what I have:
- I had a virtual machine created with Slackware current (about a year ago. kernel was 4.3.90)
- The screen didn't maximize, so I realized I had to install Guest Additions to get that working.
- Mounted the Guest additions and tried to execute
/run/media/.../VBoxLinuxAdditions.run. It started executing fine but stopped at the error
Failed to set up vboxadd. It points to a log file, which points to another log file - neither with any useful information.
I have the compilers installed, kernel headers installed, dkms compiled (and installed, though I later read that VBox 5.* doesn't need that anymore?). I can't seem to tease more information (logs etc) from the procedure.
Virtualbox is 5.1.22, kernel 4.3.90, slackware is Slackware-current (about a year ago). gcc is 4.7.1.
Any suggestions/ideas/debugging I could try?
