Calibre not converting CBR to epub

[Savyna]

Hi Kovid,

I've been trying to convert some CBR and CBZ files to epub, but the conversions are failing every time. Please find below the error report for the CBR. Can you please tell me what I am doing wrong? I am on Mac OS 10.5.5 running on a mid 2014 Macbook Pro. The source file is CBR and not zipped. I tried zipping it and then converting but with the same results.
Many thanks

calibre.utils.unrar.UNRARError: Not a RAR archive

According to that error message, the unrar library thinks your CBR file is not a valid RAR archive. Hard to say more without access to the file in question.
