Yo mate, With such little information it's pretty hard to help you. Would you mind running again with --debug flag ?

I'm already use the debug and that is the output of my debug. This is how this happen

• download a few files and everything works properly, then
• download this one file that take a very long time and i open 2 more terminal to download another book
• that one file failed to download an give me this issue https://github.com/nicohaenggi/SafariBooks-Downloader/issues/34 and the other downloaded successfully and one more the same issue #34
• i try to redownload again and it gives me this issue.

I'm using ubuntu 18.04 also for additional issue while downloading I'm using Guake, when i try to quit from guake after this issue happen i can't close guake

I already use the downloader from Ubuntu default terminal and it gives me this error as well.

I see. Just to make sure, in your screenshot, you did not put any other arguments such as the book ID, I guess it is just in order to illustrate your issue, right? If so, I'll try to reproduce (I ain't on my personal computer right now 😬) and come back to you.

The Guake issue is not from the downloader but from the Guake itself i just find out its issue in their code.
