Ubuntu 19.04 can not install winehq-staging

How does one install winehq-staging on Ubuntu 19.04 given that winehq is full two days late on having a repository for disco dingo?

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

Solution 1:

You can easily use the version for bionic (18.04.2) for the time until they have a release for it. To do so, you need to change the source list file accordingly.

I assume here you followed every other step mentioned on the winehq page you can do the following:

sudo sed -i.bak 's/disco/bionic/g' /etc/apt/sources.list.d/wine-staging.list

This will change the the source list file for wine-staging and creates a copy of the original file now ending with .bak. This should you enable to

sudo apt update
sudo apt install wine-staging

on your computer. When they have released the version for wine on 19.04 (disco) you can simply remove the changed file, rename the old one back and then do an upgrade to the package:

sudo rm /etc/apt/sources.list.d/wine-staging.list
sudo mv /etc/apt/sources.list.d/wine-staging.list.bak /etc/apt/sources.list.d/wine-staging.list
sudo apt update
sudo apt upgrade wine-staging

Solution 2:

https://wiki.winehq.org/Ubuntu

stable version will work as expected, but if stagging is needed this is what I discovered, otherwise, I get unresolved dependency.

names and version do not match in the repository table, so for

Ubuntu 19.04 disco -> sudo apt-add-repository 'deb https://dl.winehq.org/wine-builds/ubuntu/ cosmic main'

Ubuntu 18.04 bionic -> sudo apt-add-repository 'deb https://dl.winehq.org/wine-builds/ubuntu/ xenial main'
