fresh demo install on linux (ubuntu 21.04) doesn't work 1.1.32 (steam)

[physics is fun]

"failed to load mods: Failed to load image data ... __base__/graphics/terrain/hr-sand-2.png"
I've never played this game before and I thought I'd try the demo as it seems very well regarded. I know it is suggested that bugs are created on the factorio forum but I don't own the game so not going to create an account to submit a bug.

Post the whole log. There are a lot of reasons this could be happening and giving us the whole log helps narrow things down.

I can't find any log to speak of. If you can give me a log file name or partial directory I can try and find one. The steam install location seems pretty convoluted. The factorio executable lives here: <home dir>/.var/app/com.valvesoftware.Steam/.local/share/Steam/steamapps/common/Factorio Demo/bin/x64/factorio

while the offending png lives here: <home dir>/.var/app/com.valvesoftware.Steam/.local/share/Steam/steamapps/common/Factorio Demo/data/base/graphics/terrain/hr-sand-2.png

Note that the png has the correct username and opens into an image view with no issues so doesn't appear corrupt

[PunCrathod]

On linux the logfiles are supposed to be in ~/.factorio

[physics is fun]

Thanks for getting back quickly. There is no ~/.factorio on my machine. Looks like steam is a flatpak app hence the strange directory setup

[PunCrathod]

Flatpak sandboxes apps. As far as I know if a program tries to access ~/ it will access ~/.var/app/sandboxinstance/ instead. So in this case I think factorio would put the logs in ~/.var/app/com.valvesoftware.steam/.factorio

[physics is fun]

Thanks, yes it was in there. Here are the contents of factorio-current.log

It doesn't work, you say. But it doesn't crash either?

[physics is fun]

No, it doesn't crash. It shows a message box titled "Error loading mods". The contents are described in the first post. I have 3 options: "Disable all mods", "Restart", "Exit". If I click to disable all mods it restarts but I get exactly the same dialogue box again. Restart predictably does the same

[PunCrathod]

As far as I can tell "IDAT: CRC error" comes from the library used to load .png files. That library is relatively simple and heavily audited&tested so I doubt this is a bug in the library itself. The log does not show anything else that could be blamed for the error. Therefore my best guess is that the png file itself is corrupted just enough for the CRC to not match but not enough to prevent it from loading in image view.

You could try downloading the demo from factorios website to rule out steam being the problem. You don't need any accounts for that.

[physics is fun]

ok, thanks, I'll try that

[physics is fun]

demo version from the factorio website seems to work fine

I have an account on the official forums. I'll throw a link to this thread at it.
Seems like somerthing they should hear about...

I hope I descriped the issue properly...
