I am unable to run any virtualization software. Namely Vmware or Virtualbox. Since both of them asks me to install (or produces some error which pints to ) installing build essentials and latest linux headers.
So my problem starts with the following problem
When I try to update using
sudo apt-get install linux-headers-`uname -r`
What I get is
Reading package lists... Done Building dependency tree
Reading state information... Done Package linux-headers-3.13.0-45-generic is not available, but is referred to by another package. This may mean that the package is missing, has been obsoleted, or is only available from another source
E: Package 'linux-headers-3.13.0-45-generic' has no installation candidate
When I try to determine what I have by running
apt-cache search linux-headers-
I have tried most of the things that I could find in Google and nothing quite helped. Hence hoped to find some solution here.
