Hey everyone. I’d like to preface this post by saying that I understand that Blizzard does not officially support Linux, and that we are but a small percentage of Blizzard gamers. However, we are begging for some help with this issue. The bnet linux gaming community still comprises of a lot of people and both WOTLK and OW2 are coming very soon.
Now for the description of the issues. This assumes bnet is being installed through the Lutris script.
The first issue we now encounter is the fact that when installing bnet, the install does not complete. We can see in the Lutris log the following message:

Here starts the inconsistencies. (Apologies for the lack of screenshots, I do not have a high enough trust level to send these)
For some/sometimes, the bnet installer will hang at Updating Battle.net Update Agent...
Some other times, the next installer window will open, the install will continue for a bit until it hangs in the Battle.net Installation window, at Installing Battle.net... (0%)
Cancelling the install allows for the Lutris install to finish. From there, we can choose to directly run the Battle.net installer in our wine prefix. This is needed if the installer hung at Updating Battle.net Update Agent....
Doing this might again make the installer hang at Battle.net Installation, but Battle.net seems to be installed. We can then close the installer and open the launcher.
Overwatch is used in the screenshots below but the behaviour seems to be the same for at the very least WoW too, most likely every game.
Trying to install a game might hang on the Overwatch Installation window, which will be blank apart from a spinning loading logo in the bottom right. Restarting the launcher multiple times or changing wine versions (some people believe that older version like 6.4 and 7.1 work better than newer ones) might allow us to instead get the install window to properly display and then hang when clicking on Install. The 22.10 GB required normally in the bottom left may never appear, instead staying at Calculating Size. Otherwise, it may periodically switch between the two.
This is as far as I can get. However, other reports indicate that we may be able to get past this installation screen. Then the update progress bar would appear under the Install button, like normal. I was able to get there at one point but the bar did not seem to progress. However, someone said that the agent was apparently updating the game just a little every so often. So it may be ultimately possible to install a game after hours of fiddling, however nobody else was able to reproduce the result at this time
By opening our task manager, we can see that the Agent.exe process is constantly quitting and coming back. BlizzardError.exe does the same. If we navigate to the equivalent of C:\ProgramData\Battle.net\Agent\Agent.8009\Errors, we can see the agent is writing errors quite often, every 10 seconds or so. I have a sample of the crash but could not send it because of my trust level.
We can also see that the product.db in C:\ProgramData\Battle.net\Agent is constantly being recreated by noticing that some product.db.new and product.db.old files are getting created/removed
Other people might experience different behaviours of the launcher than what is reported here. However I am confident that the Agent issue is common to all of us and the root of the issues
Dear Battle.net team. Could you please help us and either look into this or give us information needed to fix this? As I said above, WOTLK and OW2 are coming soon. A lot of us are very excited to play these and we really hope we can get the Battle.net launcher working before they release
Thank you very much for reading. Have a great day 
Hope it’s ok
