Public bug reported:
I have several versions of gcc installed (4.4, 4.7 and 4.9). gcc links
to 4.4 (it's my default). When upgrading the kernel (with apt upgrade),
the dependency system correctly computes that it has to rebuild the
virtualbox driver (vboxdrv). But doing so, it uses gcc 4.4. The compiled
driver is incompatible with the kernel (as the kernel is compiled with
gcc 4.9).
I had this error in dmesg: vboxdrv: Unknown symbol mcount (err 0)
So the update process fails (and correctly indicates that it has
failed).
To fix the issues, I did this:
sudo sudo update-alternatives --config gcc
and selected gcc-4.9.
sudo apt remove virtualbox
sudo apt install virtualbox
And the problem was solved.
I guess the compilation of vboxdrv must check if it uses the same
version of gcc that was used to build the kernel.
