Calibre not launcing on archlinux

[Henry Flower]

I recently updated calibre on Arch to 0.3.88-1; trying to launch it, I now get an error:

Traceback (most recent call last):
  File "/usr/bin/calibre", line 18, in <module>
    from calibre.gui2.main import main

Any thoughts?

sudo rm -r /usr/lib/calibre/calibre/ebooks/chardet

Thanks, that did it.

Happy New Year!

I got exactly the same error and did sudo rm -r /usr/lib/calibre/calibre/ebooks/chardet, but then I got:

Help, please...

You've got a broken PyQt installation on your syste, I suggest uninstalling calibre and using the binary build, which includes all dependencies from here: http://calibre-ebook.com/download_linux

Thanks for the quick reply, Ihave reinstalled calibre as u told me and even though I can get to open calibre, it shows the following in the console:

Failed to initialize plugin: ISBNDB (1, 0, 0)
Failed to initialize plugin: <class 'calibre.ebooks.metadata.sources.isbndb.ISBNDB'>

I have searched through the plugins and have not found ISBNDB

[kovidgoyal]

The list only shows initialized plugins. Run calibre as

calibre-debug -g

you may get more info. Though since you probably arent using isbndb anyway, it doesn't really matter.

Ok, this is what I got:

Starting up...

So I simply closed it and then did "sudo chmod -R 755 /home/mrnuflo/.config/calibre" and it worked flawlessly. Thank you very much for your quick replies and help and for pointing me in the right direction! I love your app, good work!! I hope I'll become a programmer some day soon and give back to community too!!
