How to install Battle.Net and run Blizzard games on Ubuntu 18.10

I base much of my answer on https://www.maketecheasier.com/play-hearthstone-on-ubuntu-linux/ which was the most concise solution, that had still to be tweaked.

Vanilla installation of Ubuntu 18.10 64bit.

Everything in the answer supposes you run it from terminal, even when not explicitly stated.

1. Add WINE staging repository and install it

(WineHQ). Note that you will work with 32bit installations of games, etc.

sudo dpkg --add-architecture i386 wget -nc https://dl.winehq.org/wine-builds/winehq.key sudo apt-key add winehq.key sudo apt-add-repository https://dl.winehq.org/wine-builds/ubuntu/ sudo apt update sudo apt install --install-recommends winehq-staging

2. Configure WINE

Run winecfg

In the Staging tab, check the following boxes:

• Enable CSMT

• Enable VAAPI

• Enable EAX

• Hide Wine version from applications

In the Libraries tab, add entry locationapi, Edit it and select "Disable":

Now, some other answers on the net say, you have to disable d3d11 as well, but Battle.net launcher apparently doesn't install without it and it turned out that there was no problem running at least Hearthstone and Diablo 3 with D3D11.

In the Applications tab, select Windows version 8.1:

3. Tweak WINE with winetricks

Download winetricks script:

wget https://raw.githubusercontent.com/Winetricks/winetricks/master/src/winetricks chmod +x winetricks Now, you will be using 32bit WINE libraries and software versions, so you should prepare all your future runs from terminal for it:

cat >> ~/.bashrc export WINEARCH=win32 export WINEPREFIX=~/.wine32

Press [CTRL+D] after pasting these 3 lines into terminal, to end adding lines to .bashrc .

Close your existing terminal and open a new one, so that environment variables will be working.

Launch winetricks:

./winetricks

• use the default prefix
• select "Install a Windows DLL or Component" option.
• From there, install "ie8" and "corefonts".

The installs take some time, and you have to click through multiple "OK" buttons.

4. Get normal Windows Battle.net installer from Blizzard Download page

Now, after downloading, you wont generally be able to just click on the resulting .exe file to launch it with Wine, because you need the environment variables WINEARCH and WINEPREFIX. So in general you launch it from terminal with

cd Downloads wine Battle.net-Setup.exe

Then you should be able to install Hearthstone and play it via launcher app.

As this solution relies on WINE environment variables, so you wont be able to just click on the exe files. You will get a missing DLL Windows error box, if you do.

Instead when you need to relaunch Battle.net launcher after quitting it, use:

cd ~/.wine32/drive_c/Program\ Files/Battle.net/
wine Battle.net\ Launcher.exe

For my install of Overwatch on Ubuntu 18.10, my procedure differed from the above and I'm commenting because most of us end up using bits from several guides.

Differences

I removed old versions of wine by deleting all .wine and .wine32 folders but keeping a backup of old game configs, and any large .dat files saved games and screenshots etc.

Then I removed with

sudo apt remove wine wine-stable wine-staging winehq-stable winehq-staging wine-devel

I tried previous wine versions too so I did a clean OS install in my case (backed up first).

It's important for people to know that the apt key changed on WineHQ on 19th December 2018 and those following old guides will get the wrong key. Your steps have the correct key for those finding this from Google.*

It's also important to add the correct apt repository:

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

I set Windows version to 10. On previous wine prefix attempts I tried other versions and had to change a few times during the install steps BUT on a new prefix, just using Windows 10 worked on a 64 bit (default) prefix.

I did

sudo apt install winbind

but that might come with the default install.

ie8 did not work for me, but I didn't need it. For some reason I didn't need the wine-mono or wine-gecko components, but I had needed those on previous OS installs.

I installed the vcrun2015 component before downloading Battle.net-Setup.exe.

I didn't follow the 3 lines about using 32 bit wine and it worked fine without this step or creating a .wine32

Thanks for your writeup and it seems to be a huge or impossible challenge to unify documentation across all the different OS's versions, games, etc. I think the documentation on WineHQ has improved a lot.
