Preview command doesn't work on Linux

[RandomHashTags]

I tried this command: swift package --disable-sandbox preview-documentation --target APIDocumentation

And got this output:

Build of target: 'APIDocumentation' complete! (4.04s)
Template: /usr/lib/swift/share/docc/render
Error: Error Domain=NSCocoaErrorDomain Code=513 "You don’t have permission."
error: 'docc preview' invocation failed with a nonzero exit code: '1'.

Note: The Swift-DocC Preview plugin requires passing the '--disable-sandbox' flag
to the Swift Package Manager because it requires local network access to
run a local web server. See 'swift package plugin preview-documentation --help' for details.

Checklist

• If possible, I've reproduced the issue using the main branch of this package.

Expected behavior

Start web server to preview docc documentation.

Actual behavior

this is also happening to me in an Ubuntu 24.04 devcontainer

I think this issue should be transferred to swiftlang/swift-docc as the docc subcommands are the source of the problem, not this repo.

Edit: All unit tests pass on my Linux machine for swiftlang/swift-docc. The problem is this repo.
