I'm using VB 5.2.26 as Host

And Guest: Mint 19 Cinnamon Kernel 4.15.0.-48

Already installed and Reinstalled) VBox_GAs_5.2.26

Shared folders Vlipboard is not working and using a USB Stick, too.
What's going wrong?

We need to see a complete VBox.log, from a complete VM run, where the problem occurs:

• Start the VM from cold-boot (not from a paused or saved state) / Observe problem / Shutdown the VM (force close it if you have to).
• With the VM completely shut down (not paused or saved), right-click on the VM in the VirtualBox Manager and select "Show Log".
• Save only the first "VBox.log", ZIP it and attach it to your response. See the "Upload attachment" tab below the reply form.

Here the log informations you need.

According to the log, shared folders is working.

00:00:20.797945 VMMDev: Guest Log: 00:00:00.026516 automount vbsvcAutoMountWorker: Shared folder 'Win10SHARE' was mounted to '/media/sf_Win10SHARE'

I don't like the fact that the share name mixes case. I've seen that be the cause of mysterious failures in the past: the Windows host doesn't much care about case, but AFAIK Linux does.

I've changed the foldername to lowercase and restart the vm. After this I Add the Group 'vboxdf' to the current user. After this i can open the mappings in '/media'.

Thank you very much for help!

Glad you got it going. Marking as [Solved].

Moving to "Linux Guests" from "Windows Hosts", that's where your problem was, with the guest...
