My problem is straightforward. I did a sudo apt dist-upgrade. Nothing came up for me to respond to whatever for me to say I tweaked something wrong
I did a sudo reboot
Now I don't have access to any outbound traffic. I did the dist-upgrade yesterday, 3rd november.
This is frustrating.
Oke, I just found the solution. Maybe this is can help you.
First, the problem is the upgrade makes eth0 changed to a different name, in my case changed to ens3. You can see it using command ifconfig -a.
So, the solution is simple.
eth0 to ens3. In my VPS, the config located in /etc/network/interfaces.d/50-cloud-init.cfg. Generally, the config located in /etc/network/interfaces.ens3 to eth0. You could follow this tutorial.
