Error on updating hosts file (ubuntu 20)

[AndroiDjo]

When i run command
docker run -d \ -v /var/run/docker.sock:/tmp/docker.sock \ -v /etc/hosts:/tmp/hosts \ dvdarias/docker-hoster
got error
Traceback (most recent call last): File "hoster.py", line 135, in <module> main() File "hoster.py", line 38, in main update_hosts_file() File "hoster.py", line 107, in update_hosts_file while lines[-1].strip()=="": lines.pop() IndexError: list index out of range
and file /etc/hosts is empty.

My system is Ubuntu 20.

Here is what I did to reslove it. On the host machine :
sudo nano /etc/hosts
add a line (pretty random, I used this one) :
127.0.0.1 localhost me.local
and then :
docker restart docker-hoster

Hope this helps someone, It's the first link I found when I encountered the error :)
