EOFError when trying the wrong key first about dedrm_tools HOT 12 CLOSED

I don't recognize those errors at all. I'll try to reproduce, but I'd be surprised if it was a plugin error.

from dedrm_tools.

I don't have a valid, incorrect .der file to test with. Could you email me one of yours? [email protected] Thanks.

I can't reproduce on Windows with calibre 2.2.2 and 6.,3.3. Just trying with 2.4.0 and 6.3.4

Can't reproduce with 6.3.4 and 2.2.2, although there's something nasty going on at the end.

And as expected, I can't reproduce with calibre 2.4.0 and DeDRM 6.3.4 either.

Since I don't have a Linux-based machine, I don't think there's a lot more that I can do. But if you could post a full log, I could try to spot some way to catch the error and allow the further keys to be used. (The snippets you've posted so far give no context as to when the error happens.)

I suspect that the error is actually down to the particular variety and version of Linux you have.

and then, as above.

I didn't think that would be very helpful but there you go ...

from dedrm_tools.

Thanks. It is, at least, helpful in a negative way - there's nothing obvious in there that's causing a problem.

So, a closer look at the error:

No node found for item that was just removed: QUrl( "file:///home/sanotehu/Documents/My Digital Editions/manifest.xml" )

Clearly something to do with Adobe Digital Editions, but nothing that the DeDRM plugin code is referencing. A puzzle indeed.

I'll see if I can add some more error handling to get both keys tried no matter what's throwing the error.

from dedrm_tools.

OK, I have a test version for you to try. Please email me directly, [email protected] and I'll send it to you.

from dedrm_tools.

I don't seem to have received an email from you. If you are still having problems, let me know by email and I'll re-open this issue.

from dedrm_tools.

I'm also seeing this issue with DeDRM 6.6.3 and Calibre 3.36.

from dedrm_tools.

Post a log if you want someone to take a look.
