Hi, Thanks for your suggestion, I decided to upgrade to 18.04.4 and I ran a few times the following commands (from root):
sudo apt autoremove sudo apt-get update sudo apt-get upgrade sudo apt update sudo apt upgrade I have 4 servers and I upgraded all of them and 3 of them are working properly, however one server apache is not working, I can't restart apache (with "sudo systemctl restart apache2" - it's not responding) and the website is not working. How can I fix it now? The server didn't respond after reboot once (after 2 reboots) and I had to shut it down and restart it again.
