local-cname's Issues

Exception occurred: getaddrinfo() takes no keyword arguments

I installed local-cname on a new Ubuntu 18.04 VM. First I installed Python on it with "sudo apt-get install python-pip" and then local-cname with "sudo pip install -U local-cname". When I tried "sudo local-cname google.com duckduckgo.com" I received the following: "ImportError: No module named pathlib". I then installed pathlib with "sudo pip install pathlib".
Now when I try "sudo local-cname google.com duckduckgo.com" I receive this: "Resolving duckduckgo.com .. EXCEPTION OCCURRED: getaddrinfo() takes no keyword arguments". Please see the screenshot attached.

Error running inside docker

Hi.. I'm getting the following error when running inside docker when I stop the service.

OSError: [Errno 16] Device or resource busy: '/etc/hosts.local-cname-backup' -> '/etc/hosts'

/etc/hosts is mounted by the docker daemon so the rename will fail.

# mount | grep hosts
/dev/nvme0n1p1 on /etc/hosts type xfs (rw,relatime,seclabel,attr2,inode64,noquota)

A good way of fixing could be something like detecting if /etc/hosts is mounted and if do, just do something like a cat over the file (like the pseudo code):

cat /etc/hosts.local-cname-backup > /etc/hosts
rm  /etc/hosts.local-cname-backup
