shared folders unaccessible after upgrade to 4.0.4

[marekb]

Hello,

After upgrading the VirtualBox to 4.0.4 version I am no longer able to mount shared folders on the guest Ubuntu 11.04 (amd64). When using mount command I receive "device not found" error message.

I've found a hint in the syslog however:

Code: Select all

kernel: [   18.560512] vboxdrv: exports duplicate symbol RTMemExecFree (owned by vboxguest)
kernel: [   19.368381] vboxdrv: exports duplicate symbol RTMemExecFree (owned by vboxguest)
modprobe: FATAL: Error inserting vboxsf (/lib/modules/2.6.35-25-generic/updates/dkms/vboxsf.ko): Invalid module format

Can anybody help me with this? Unfortunately I am no expert on Ubuntu.
My host system is Windows Prof. 7 64-bit.

Best wishes
Marek

From the looks of it you have installed the VirtualBox main program in the guest and this is torking the guests modules.
Look in your Ubuntu guests package manager and make sure that the VirtualBox program in not installed (remove it if it is) and then install the guest additions again.
