Hello, it was working ok until yesterday. Today I get a pop-up saying:
Something went awry while we were trying to check for updates. Please try again, and contact Magic: The Gathering Arena support if the problem persists. Error Code: Config: -2146233088
I’ve tried removing the game and reinstalling, it installed fine but the error is still there.
I just tried it and it worked.
Yesterday, instead of starting the game right away, it opened the patcher and did some update to version “1004_somenumbers”.
I can only recommend removing the entire wineprefix and trying to install again, but since you already did it, I’m clueless.
I’m having the same problem; one day it worked fine, and when I tried to open it the next day the error happened. Uninstalling and reinstalling did nothing. Somewhere in the process of purging and reinstalling every Lutris and Wine thing I could find it started working again, and earlier today I accidentally pressed alt+q instead of alt+tab and now the problem is there again.
Also experiencing this error. Tried fresh install and no luck. Have had MTGA working for the last 2 months no problem in Lutris until yesterdays update.
I’m having this issue as well.
What Wine version are y’all using? Please stick to tkg-mtga-3.21 it’s supposed to fix this. If that’s the version then this is something Wine has to fix.
I had the same problem with the default wine version (tkg-mtga-3.21-x86_64) and changed and changed to newest I had (4.0-rc2 staging) and it worked. Might want to try running on somewhat recent version for now until they fix it in Lutris.
I wish I found this thread earlier ! I had the same issue and solved it using wine 4.0rc7-staging from wineHQ.
The underlying issue was using an older GnuTLS version in the wine mtga version, which lead to connection issues to the update servers. I guess the freeze before the 4.0 wine release meant that the GnuTLS version was not updated recently.
I switched my install to the 4.0 release version through the Lutris WINE runners, and I keep getting the “gcThreadContext” error as I’m downloading the update files. Currently only 2 files remaining, one of which keeps not completing. Unsure if I need to keep brute-forcing this, as I have had to relaunch the game like 10 times now just to get most of the update content downloaded.
Would really appreciate an updated Lutris build script for this 
And of course next attempt downloaded the last 2 files, so far so good.
For updates I sometimes use the system option of running on a single core. Of course it’s not usable for the game itself, but to download the files I feel like it avoids some issues. Once download is complete, I quit the game, remove the option and relaunch.
The generic problem with updates was that Mono apparently timed out. The tkg-mtga version of lutris has a timeout timer 10x bigger than regular, that’s why that was the version adopted.
I’ve been through a few updates and the client seems to finally be reaching a good point for Linux+Wine!
