I am trying to install Wine however when I run:

~$ sudo add-apt-repository 'deb https://dl.winehq.org/wine-builds/ubuntu/ cosmic main'

I get:

LSB codename: 'bionic'.
This codename isn't currently supported.
Please check your LSB information with "lsb_release -a".

I've already tried (in order):

sudo apt-get install python3-software-properties
sudo apt-get install apt-file
sudo apt install python-software-properties
sudo apt-get update
sudo apt-get install --reinstall python-software-properties
sudo apt install --reinstall software-properties-common

(I followed the first two answers from How to add a PPA on a server?). When I search for add-apt-repository, I get:

~$  apt-file search add-apt-repository

software-properties-common: /usr/bin/add-apt-repository
software-properties-common: /usr/share/man/man1/add-apt-repository.1.gz

How do I get add-apt-repository to work?

    If it's 18.04, why are you trying to add repository for cosmic. Try replacing cosmic with bionic, Moreover, wine is in official Ubuntu repository. Therefore, you can drop the idea of adding a repository.

  • This may be a dumb question but how do you tell if you should run Bionic or Cosmic? I thought 18.04 corresponded to bionic. Should I use packages for newer versions of Ubuntu from now on?

    Look at the command you used to add repository. It clearly has cosmic in its name which corresponds to 18.10 while bionic is 18.04. Should I use packages for newer versions of Ubuntu from now on?: No. They might create dependency issues. Try K7AAY's answer once.

For Wine to work, you need 32-bit capability, and since you are using 18.04, you need to use bionic, not cosmic, so these commands are more appropriate:

sudo dpkg --add-architecture i386
wget -qO - https://dl.winehq.org/wine-builds/winehq.key | sudo apt-key add - 
sudo apt-add-repository 'deb https://dl.winehq.org/wine-builds/ubuntu/ bionic main'
sudo apt-get update
sudo apt-get install --install-recommends winehq-stable
