fksdlofioenvdfsdji,
How did you "want to update && upgrade your server"?
How many kernels can your /boot partition hold? (What is the size of your /boot partition?)
Contents of "50unattended-upgrades" is misleading, as there is no mention of the new configuration variable Unattended-Upgrade::Remove-New-Unused-Dependencies which defaults to "true" in the file (in Ubuntu 16.04).
Replacing line
// Unattended-Upgrade::Remove-Unused-Dependencies "false";
by
Unattended-Upgrade::Remove-Unused-Dependencies "true";
may help you, if you don't mind that it removes all packages that 'sudo apt-get autoremove' would.
