cannot open calibre on osx 10.6-- "Calibre is already running" message

jlip · 10-21-2009, 10:09 AM

I'm having problems running the latest version of Calibre (0.6.19)--I'm on os X 10.6.1; I keep getting the error message: "calibre is already running...if you are sure it is not running, try deleting the file ... .calibre_calibre GUI.lock."

The problem is that the GUI lock file does not exist (the ls -la command shows no hidden files containing the word calibre).

I have removed all references to calibre in ~/Library/Preferences, removed, reinstalled, rebooted-- all to no avail.

The problem seems to be related to only this user account as calibre runs fine in a newly created account.

the console log shows the following (note, the .fonts directory does not exist in the problem account):

Traceback (most recent call last):
File "calibre/__init__.pyo", line 414, in <module>
File "os.pyo", line 157, in makedirs
OSError: [Errno 13] Permission denied: '/Users/JBL/.fonts'
Traceback (most recent call last):
File "calibre/utils/ipc/__init__.pyo", line 28, in run
File "multiprocessing/connection.pyo", line 134, in Client
File "multiprocessing/connection.pyo", line 252, in SocketClient
File "<string>", line 1, in connect
error: [Errno 2] No such file or directory

Any help would be greatly appreciated.

There seems to be something wrong with the permissions of your home directory.

ls -ld ~

Thank you.
The owner of my home directory was another user on the computer. I'm not sure how that happened, but once fixed, all is working as expected.
thx again

I had the identical problem and was also able to fix it by changing the owner of my home directory so thanks to both of you for the question and answer.

I finally figured out how to change the home directory permissions and it worked! Thanks Kovid!
