After ubuntu is installed in VirtualBox, shared folders cannot be mounted. virtualboxubuntu

It has been almost a year since I installed ubuntu12 with VirtualBox4.2.12. However, the shared folder of the host cannot be mounted during this period, even if the "Enhancement package" is installed. I always thought it was Because ubuntu was not configured. Some people on the Internet said that it was because the kernel header file was not installed. As a result, the peripheral modules of the kernel cannot call the kernel function.

Later, I carefully observed the installation process of the "Enhancement feature package" and found that there was such a record. I did not find it until I was careless...

Now that you have found the reason, install the headers of the kernel. I searched a lot on the Internet to explain how to install kernel-devel. This version is not suitable for ubuntu, run the following command to install the headers of the kernel:

At this point, it seems that the problem mentioned above has been fixed. If you try to mount the shared folder again with joy, the tragedy will happen again and you still cannot mount the shared folder.

So far, it is completely speechless...

Finally, the landlord saw the problem that the VirtualBox version was too low, so he changed the version 4.3.8 to a later version. ORACLE is really... mounting shared folders should be frequently used in Virtual Machine Software. How can this problem still occur ??? (Or the 4.2.12 version also has a solution, but I didn't find it ??? Please advise if you have any experts !)

Ps: Two commands that may be used to view the system kernel version
