Recently, I had an issue where I had no loopback device in Linux Mint 18.2 MATE, which occurred after upgrading from 18.1 MATE.

Diagnosis

ping localhost fails, nc -v -l -p 1234 followed by nc localhost 1234 does not connect, etc. Running ifconfig does not show a loopback device present.

Running sudo service network-manager restart and sudo service networking restart doesn't fix the issue, nor does restarting.

The only clue shows up when inspecting /var/log/syslog:

# $ ssh root@host ./kexec-installer
## Customize it like this
# # custom-installer.nix
# import ./kexec-installer.nix {
#   extraConfig = {pkgs, ... } {
#     user.extraUsers.root.openssh.authorizedKeys.keys = [ "<your-key>" ];
