The error in your log is:

Setting up resolvconf (1.63ubuntu9) ...
resolvconf.postinst: Error: Cannot replace the current /etc/resolv.conf with a symbolic link because it is immutable. To correct this problem, gain root privileges in a terminal and run 'chattr -i /etc/resolv.conf' and then 'dpkg --configure resolvconf'. Aborting.

Did you set /etc/resolv.conf immutable on your system? That's not a supported configuration.
