I cannot install any package (linux-image-server, linux-server dependencies errors) [duplicate]
Solution 1:
The way I fixed this was to manually install a newer version of the linux-server package as such:
wget https://launchpad.net/ubuntu/+archive/primary/+files/linux-server_3.2.0.37.45_amd64.deb
sudo dpkg -i linux-server_3.2.0.37.45_amd64.deb
If you're running a 32-bit system you'll need a slightly different URL and package name that you can find here.
