LibreOffice documents cannot be accessed from Vbox Shared Folders

[BertN45]

Error message: Access to /media/sf_hp-data/Bert/Documents/To Do.odt was denied.

It happens only in Vbox Shared Folders and only using Ubuntu 17.10, 18.04 and Ubuntu Mate 17.10, which might be related to the LibreOffice release 5.4.4.2 and 5.4.5.1 used. Other files like music, plain text documents and photos can be accessed normally.

I do not have the same problem in e.g the Virtual Machines Peppermint 8 or Linux Mint 18.3 with LibreOffice release 5.1.6.2. Nor in the VM Xubuntu 17.10 and MX17 Linux with LibreOffice release 6.0.1.1.

That looks similar to bug #1751005. Who is the owner of /media/sf_hp-data ?
Can you share the output of:

    ls -la /media/sf_hp-data

The owner is root and vboxsf has read and write access and that is the standard assignment for Vbox shared folders and true for all my VMs. The office files are in the Bert folder.

Marking this as a duplicate of bug #1751005 as both issues will be fixed by the same update.
