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?
