Error: DOS Header magic not found

Support
1

Hi all, I’ve noticed a really bizarre issue when trying to configure some games. While changing configurations for most games seem to be fine, other games like Warhammer Chaosbane comes up with an error window saying “Lutris has encountered an error ‘DOS header magic not found.’” I have tried searching for a solution before posting here but I couldn’t find anything on what I’ve encountered, not saying it’s an issue exclusive to me but potentially a problem that’s not been caught yet.

The game seems to run and play fine with no real issues, the error only appears when trying to edit the configuration, which in turn doesn’t save the config.

Here’s the error details in full:

'DOS Header magic not found.'

Traceback (most recent call last):

pefile.PEFormatError: 'DOS Header magic not found.'

Am I missing some kind of dependency that’s stopping configs for certain games from saving? Or is it more something in the prefix itself that’s causing the problem? Would really appreciate some insight into this problem because it’s been a real thorn in my side lately.

Hi,
You have the Python module pefile installed - and lutris only uses it if installed - I don’t have it and Lutris works happily. Saying that, I wouldn’t recommend removing it unless you know another bit of software isn’t using it.

It needs a valid corresponding reference in a magic database for the file it is parsing. The default magic database(s) has a lot of file type info, but it certainly isn’t total coverage.
You might want to start by checking your libmagic packages, and that python3-magic is also installed.

If it is just one specific game breaking, then it might be a custom file which isn’t handled, in which case you’re going to need to run lutris debug info to get to the bottom of what file is being parsed that is generating the error. Either way, it might also be that lutris needs to handle that error.

Hey there! Thanks for replying, I hope you don’t mind a big reply because what I ended up discovering is quite the doozy. I did download the “python-magic” package and ended up getting an interesting result. Out of the games mentioned, downloading that package did seem to stop the error during configuration for Killing Time, as far as I could tell. However the issue persisted for Warhammer Chaosbane and XCOM, though since I haven’t properly started XCOM yet, I decided to get rid of that whole game’s prefix and redownloaded from scratch and now that game seems to work, leaving only Warhammer with the error.

I did however do more tinkering with the Chaosbane configuration and found a most peculiar solution/workaround; I was testing to see if it was the Lutris entry that was the problem, the prefix or the game folder itself and I believe I may have found the issue… It’s the icon selection in the configuration. For some reason if I leave the configuration with the blank Lutris icon, the error occurs, but if I select any other icon and it can be a completely random one, then the error no longer happens.

However if I revert the icon back to the Lutris icon then the error occurs again and can be a pain to get Lutris to recognise other .ico files, saying it can’t “find a path” to it despite having no issue selecting it before. But upon tinkering selecting a random .png and then going back to the previous .ico file it could be used again. But even then the error seems to be solved even by using a random .png selected as the icon.

Needless to say it’s an extremely weird and bizarre issue I’ve encountered, I’m not sure if this is affecting Lutris as a whole or if it’s something on my end that’s causing Lutris to behave really strangely. But for now, selecting a random icon does seem to be a decent workaround. Just note that the default Lutris icon doesn’t throw an error up for all game entries in Lutris, it only seems to affect certain games, seemingly GOG games especially, creating my own manual entries doesn’t seem to have this issue as far as I can tell.

I must also note all the games mentioned were already on my drive when I was on a different distro, so perhaps that could also be a part of the problem? Nevertheless, I hope the Lutris team looks into this in case it’s a much bigger issue that’s yet to be addressed.

Edit: You’ve posted it on GitHub issues and got some input already :+1: hopefully they can get to the bottom of why, or at least improve the error handling.

I did indeed :slight_smile: Trying my best to be as detailed and helpful as possible for the team, so fingers crossed they figure it out!
