This post is very similar to one I made for Fedora 29.
viewtopic.php?f=3&t=90578&p=434587&hili ... er#p434488
I have made the following without results:
1) Standard VBox installation of guest additions using VBox procedure
gave the results as befor that: windows scaling, shared clipboard, and drag and drop worked
as expected but NOT shared folders.
The printed log on the screen did NOT indicate any error of installation of guest additions
see enclosed screenshot.
2) I then followed the recipe from previous post that works for Fedora 29 i.e.
Restarted the machine.$sudo dnf -y update $sudo dnf -y install gcc automaker make kernel-headers kernel-devel perl $sudo yum install elfutils-libelf-devel
Still shared-folders not connected
3) I took away and re-installed shared-folders in VBox using the menu while Fedora 30 was running.
Still shared-folders not connected
What to try next?
Appreciate some help!
