Headless Server problem: 'NoneType' object has no attribute

[msteine1]

Hi there,

calibre is really great, thxs for this software.

I installed calibre on a headless ubuntu server.

Service runs and I can access the calibre service with the URL and loging in is also possible. But if I go to “ALL BOOKS” I get the following error:

Error: No books found

TypeError: Object # has no method ‘undef’

at Object.printStackTrace.implementation.createException (http://192.168.XXX.123:8080/static/stacktrace.js:81:18)

My library is here -> : /opt/owncloud/…/04_books

I tried it with other permissions (0775) and changed owner and group to root, but no success ;(

If I check the library I get the following message:

 
calibredb check_library
Traceback (most recent call last):
  File "site.py", line 58, in main
  File "site-packages/calibre/library/cli.py", line 1470, in main

  File "posixpath.py", line 352, in abspath
  File "posixpath.py", line 61, in isabs
AttributeError: 'NoneType' object has no attribute 'startswith'

Hopefully someone can help me with that.

Ignore the Quote. It seems to me, that library-path=... is a global option and does not help here

I think the pathes in my metadata.db are wrong because I copied it from a windows machine where a local instance of calibre is running.

Tried to fix it with: calibredb library-path /opt/owncloud/.../04_books

But no success and I can't find a helpfile to the library-path command.


Next thing I tried is to restore the database, but no luck either:

calibredb restore_database -r
Traceback (most recent call last):
  File "site.py", line 58, in main
  File "site-packages/calibre/library/cli.py", line 1470, in main

  File "posixpath.py", line 61, in isabs
AttributeError: 'NoneType' object has no attribute 'startswith'

Mmmh and after thinking about this problem I am frightend that I can't do what I intently wanted to do. Namely to keep the whole library with my local calibre and with my server calibre in sync via owncloud. So if in the metadata.db are pathes stored this can't work.

Is there a workaround for this? Perhaps I better make a new thread for this question, what are you guys thinking?

I can't speak for "owncloud", but I do exactly this with dropbox. I do all maintenance on my windows desktop while my server runs on a debian wheezy PVS hosted at linode.

First hint: avoid any distro-provided calibre package. The are often old and broken. Use the official package instead.

Second hint: look at
http://manual.calibre-ebook.com/server.html and
http://manual.calibre-ebook.com/faq....n-linux-server

There are many threads about syncing between a content server and a desktop calibre. Some recent ones are:

You can get a long list by searching in the forum for content server headless

I am thinking he might have problems with syncing a windows based calibre library with a linux based one because of how both OS treat Uppercase lowercase filenames differently but I could be wrong.

Could be, but calibre tries very hard to ensure that the actual files and folders have the same case as what is in the database. If necessary it changes the case of files, even though on an ignore-case filesystem like windows this is unnecessary. I haven't had a letter-case problem in the two years I have run my server on linux synced from windows.

Ok, thanks for your great tips. I am a huge step further now.

What I did:

* Database was corrupt so I generated a new one with the local Calibre
* Although the Caliber Service is running I have to run:

calibre-server --with-library=owncloud/.../books
