Building guest additions test build 6.0.9 build 131849 on Fedora 30 produces the error: The build seems to work OK despite the error, but AFAIK udevcontrol is not available in any of the default Fedora repos.

It seems that this is the last change in the VBoxGuestAdditions installation routine (trunk/src/VBox/Additions/linux/installer/vboxadd.sh), between revisions 79438 and 79510 that happened 11 days ago, on 2018-07-03 with changeset 79510, and it seems that it's in response to a bug (bugref:9138), but that's their internal bug tracker, not the public one...

I believe that the message is not an actual error, more of like a red herring. I saw it too lately with (I believe) a Kali guest. No problems there as well, but it certainly doesn't feel ... right.

From vboxadd.sh: Those look like two different commands to do the same thing. Which one executes then presumably depends on which distribution you are running. It looks like lazy programming to me as they should be wrapped in an if... fi to only be run if the executable actually exists.

Either that (preferably), or redirect the output to /dev/null. Come Monday I'll let the developers know on IRC and point them to the thread.

Apparently the issue has been addressed, it's simply that the trunk has not been updated. It's only a cosmetic issue in any case...
