`FileNotFoundError` when using `whipper cd rip`

[SpecialBomb]

This applies to whipper version 0.10.0 within a Void Linux environment. Whipper was obtained from the official Void package repository.

when using whipper cd rip, I appear to get an error regarding not being able to find a runtime directory that whipper generates in /tmp. I don't know what might be causing this. Here is an example of the output generated by the error:

[quen@slim:/tmp]$ whipper cd rip

Absolutely no clue why this is happening. I thought maybe for some reason my /tmp/ directory had restricted permissions, but they are completely normal. What could be going on here?

I got the same error running whipper on NixOS. Downgrading cdrdao from 1.2.5 to 1.2.4 fixed the issue for me, so this may be a subtle variation on https://github.com/whipper-team/whipper/issues/591.

I will give this a shot and see what it results in for me, thanks for pointing me in the right direction for the time being. I suppose someone should probably get in contact with the cdrdao maintainers.

Yeah, I think @Thra11 is right here. I ran into this on Fedora 38 (just upgraded my only system with an optical disc drive from 37 to 38...) and applying https://github.com/cdrdao/cdrdao/pull/21 to cdrdao does seem to fix it. So I think we can call this effectively the same as 591, caused by cdrdao.

I'm encountering this issue even with Arch's patched 1.2.5-3 (and 1.2.5-2), but I didn't before. Not sure what has changed, the 1.2.5-3 rebuild from a couple days ago didn't change any of the actual contents of the package and was just regenerating a missing metadata file.

Even with discs that worked before, I have the issue. Any ideas?

Nevermind, it turns out my drive numbering inexplicably changed. For some reason I get the FileNotFoundError mentioned instead of a message saying there's no CD in the drive. The drive giving me this issue is a TSSTcorp CDDVDW SH-222BB, although the drive seems to be dying because it won't read DVDs anymore and makes metallic noises with CDs (in other words, this may not be a software fault).
