In almost any action I do in Windows Subsystem for Linux, I get a notification "How to resolve host name". Why would this happen in each fresh install and how to solve it?
Linux – Unable to resolve host name in WSL

You have to edit /etc/hosts while superuser and add your machine name after the first line with localhost
127.0.0.1 localhost MYMACHINE
This will make the system not try to resolve the hostname from DNS.
Microsoft has documented how this is done on Fall Creators Update and later. The commands suggested are only an example and might vary based on the WSL instance you are using.
This question was asked in 2017, so the name of the WSL instance, might no longer be applicable to a newer version of Ubuntu WSL or if a different WSL distribution is being used. The commands that are suggested will work with any WSL distrubition on the Windows Store.
To see what commands are available for a particular distribution, run [distro.exe] /?.
For example, with Ubuntu installed:
C:> ubuntu.exe /?
Which means in order to change the default user to root in Ubuntu you would use the following command.
C:\> ubuntu config --default-user root
The documentation indicates the following:

Save and exit.
2. Then, execute:
Then, Make sure the file's first two rows looks as follows:
