I got this too, but on master.

I didn't see any commits anywhere that should have caused this, but I could have missed something.

Did the top folder inside the tarballs always have the commit hash in the name? I didn't have any old ones to check.
If they were regenerated recently and if that's a new thing, I guess the hash would be different.

Same problem here.

Maybe related:

• Package hash differs on multiple machines ziglang/zig#17064

After deleting the global cache I hit this as well, issue occurs with both master and 0.11.0.

Turns out this is an issue caused by btrfs getting the wrong hash ziglang/zig#17095, an upstream patch has been submitted to linux ziglang/zig#17095 (comment).

The hashes required on btrfs are:

I am no longer experiencing this issue on linux 6.5.3 (arch).

Hey there, I'm getting this error as well when I try to build from source. I'm running Fedora 38, and here's some more info (original issue here including zls/zig version #1491).

$ df -hT | rg '/$'

And here's the exact error:
