calibre assumes incorrect location of reader mount point?

[akos.maroy]

Hi,

I'm trying to use my Sony PRS-600 via Calibre 0.7.44 (Ubuntu 11.04), and I'm having some issues.

When I run the wizard, it detects the device fine, albeit only the main memory of the reader. But if I connect the reader again, Calibre has trouble working wit the reader, for example Calibre fails to load the reader contents, with the following error:

calibre, version 0.7.44
ERROR: Error: Error communicating with device

[Errno 30] Read-only file system: '/media/disk/Sony Reader/database/cache.xml'

Traceback (most recent call last):
  File "/usr/lib/calibre/calibre/gui2/device.py", line 64, in run
    self.result = self.func(*self.args, **self.kwargs)
  File "/usr/lib/calibre/calibre/gui2/device.py", line 308, in _books
    cardalist = self.device.books(oncard='carda')
  File "/usr/lib/calibre/calibre/devices/prs505/driver.py", line 186, in books
    bl = USBMS.books(self, oncard=oncard, end_session=end_session)
  File "/usr/lib/calibre/calibre/devices/usbms/driver.py", line 162, in books
    self.sync_booklists((None, bl, None))
  File "/usr/lib/calibre/calibre/devices/prs505/driver.py", line 212, in sync_booklists
    c.write()
  File "/usr/lib/calibre/calibre/devices/prs505/sony_cache.py", line 724, in write
    with open(path, 'wb') as f:
IOError: [Errno 30] Read-only file system: '/media/disk/Sony Reader/database/cache.xml'

even though the file mentioned is there, and writeable:

$ ls -la /media/disk/Sony\ Reader/database/cache.xml
-rw-r--r-- 1 maroy maroy 16926 2011-12-18 20:31 /media/disk/Sony Reader/database/cache.xml

when trying to download a book, Calibre will assume a mount point of /media/sony, even though the internal memory and memory card mount points for the reader are /media/disk and /media/READER. thus book downloading doesn't work.

interestingly, if I re-run the wizard, it works fine until the next reconnect.

what am I doing wrong?

That is a very old version of Calibre so I suspect you may have trouble getting an answer. Is there any reason you are not running a recent version (8.31 being the current version).

the main reason is that this is the version that comes from ubuntu's package repository...

[itimpi]

Many of the repository installs are faulty which is why they are not officially supported in this forum. I would expect you would get better results by using the binary install from the Calibre home site.

Use Synaptic to completly remove.
Then Run to the Calibre Linux download page and use that Commandline installer.

I made a Menu item(under System Tools) and pasted that into launcher . Now all I do is click that when I see an Update notice

thanks for the tip. so I removed the package installed version, and installed according to the documentation on the calibre site, and now I have 0.8.31.

and I still have the same issue:

[Errno 30] Read-only file system: '/media/disk/Sony Reader/database/cache.xml'

Traceback (most recent call last):
  File "site-packages/calibre/gui2/device.py", line 81, in run

IOError: [Errno 30] Read-only file system: '/media/disk/Sony Reader/database/cache.xml'

whereas the file in question is there as before:

$ ls -l "/media/disk/Sony Reader/database/cache.xml"
-rw-r--r-- 1 maroy maroy 16928 2011-12-19 07:52 /media/disk/Sony Reader/database/cache.xml

thanks, this was the problem indeed.

maybe a more descriptive error message would help in recognizing the real issue.

It certainly could be more descriptive, since this is a Linux OS level error message where do we send the suggestion?
