I'm running 18.04, and I'm attempting to install Wine, which has an unsigned repository. I tried bypassing this by using the --allow-unauthenticated flag, but I get an error

$ sudo apt-add-repository https:/ --allow-unauthenticated
Usage: apt-add-repository <sourceline>
apt-add-repository is a script for adding apt sources.list entries.
It can be used to add any repository and also provides a shorthand
syntax for adding a Launchpad PPA (Personal Package Archive)
repository.
<sourceline> - The apt repository source line to add. This is one of: a complete apt line in quotes, a repo url and areas in quotes (areas defaults to 'main') a PPA shortcut. a distro component Examples: apt-add-repository 'deb stable myrepo' apt-add-repository ' myrepo' apt-add-repository ' free non-free' apt-add-repository apt-add-repository ppa:user/repository apt-add-repository ppa:user/distro/repository apt-add-repository multiverse
If --remove is given the tool will remove the given sourceline from your
sources.list
apt-add-repository: error: no such option: --allow-unauthenticated

I've seen other users on the site with the same version of Ubuntu claim this option works. What am I doing wrong here?

You may use the option --allow-unauthenticated with the commands apt or apt-get but not with the command add-apt-repository.

Please take a look at where it is very well explained how to add the desired repository.

If you have previously installed a Wine package from another repository, please remove it and any packages that depend on it (e.g., wine-mono, wine-gecko, winetricks) before attempting to install the WineHQ packages, as they may cause dependency conflicts.

If your system is 64 bit, enable 32 bit architecture (if you haven't already):

sudo dpkg --add-architecture i386 

Then run the following commands:

wget -nc
sudo apt-key add Release.key
sudo apt-add-repository 

Now you need to update the cache with

sudo apt update

And finally install with

sudo apt-get install --install-recommends winehq-stable
