Failed to start Wait for all "auto" /etc/network/ to be up for network-online.target
Did this unix.stackexchange.com/questions/209832/debian-sys... - did not help Neither the gateway
nor the host is
pinged . _

As a result, the web server got up :(

Unclear. I did not install anything new either on win10 or on ubuntu. Before that, I did a weekly backup of the entire virtual machine using powershell. After it, everything worked for several hours, added a couple of news to the site. First, access from the host 192.168.1.11 to the web server 192.168.1.6 was lost, but it worked from the outside, through the domain name, then this one also disappeared. Then I experimented with everything. The only thing I achieved was that during the download the pause disappeared with the network interface being raised, but the pings still do not go. It is also aggravated by the fact that the clipboard between the virtual machine and the host does not work. Previously, I just used ssh. I'll try to create another virtual machine now to see if there will be problems with the new one.
