Hi, Running the command "sudo apachectl configtest" returns "Syntax OK".
Running "sudo systemctl restart apache2" doesn't respond. But a few minutes ago it worked and the website worked. I rebooted again and now again it's not working. The problem is that apache doesn't restart after rebooting. אורי u...@speedy.net On Thu, Jun 11, 2020 at 6:29 AM אורי <u...@speedy.net> wrote: > 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.
