Not using steam, also I'm on Linux.
I got a CRC error twice now when launching factorio space age. First time I fixed it by replacing the mentioned file with a non corrupted one from the installer archive.
Worked but now it's happening again, a different tree.jpg this time. Haven't tried anything yet because I think it might happen again in a few days.
Is my SSD or ram fried or could there be another explanation?
Has this happened to anyone before?
Searching online I found people had this issue with mods, but nobody had it with the space age mods.
Edit: this is the exact error this time:
Failed to load mods: IDAT: CRC error: __base__/graphics/entity/tree/09/tree-09-d-normal.png
this is a screenshot of the corrupt file. Lemmy won't accept it as an image so I had to go this way:

this is what it's supposed to look like:

edit2: this time replacing this image worked again. Factorio launches. Let's see how long it takes until I see this error again.
