OSX Sequoia Update - unable to load database

mobile_marsupial · Yesterday, 09:16 PM

I have updated my operating system to Mac OSX Sequoia 15.7.3 (24G419) this morning. Upon restarting the computer I am unable to open Calibre. I receive the following error:

Quote:

calibre, version 8.16.2
ERROR: Bad database location: Bad database location '/Volumes/volume(sda2)/Calibre Library'. calibre will now quit.

Traceback (most recent call last):
File "calibre/gui2/main.py", line 298, in initialize_db_stage2
File "calibre/db/legacy.py", line 191, in __init__
File "calibre/db/legacy.py", line 45, in create_backend
File "calibre/db/backend.py", line 517, in __init__
File "calibre/utils/filenames.py", line 127, in is_case_sensitive
PermissionError: [Errno 13] Permission denied: '/Volumes/volume(sda2)/Calibre Library/calibre_test_case_sensitivity.txt'

Anyone have any idea on how to fix?

Thanks.

Thanks Kovidgoyal.
There is nothing in the "Permission Denied" section that you shared that seems to help.

* You can get permission denied errors if you are using an SD card with write protect enabled.
(not using an SD card and "write protect" is not enabled)

*On macOS if you get permission errors when connecting a device to calibre, you can fix that by looking under System Preferences > Security and Privacy > Privacy > Files and Folders.
(I am not connecting a device. Calibre has full drive access in Privacy)

*If you, or some program you used changed the file permissions of the files in question to read only.
(No permissions have changed. All files on this drive are read/write to everyone)

* If there is a filesystem error on the device which caused your operating system to mount the filesystem in read only mode or mark a particular file as read only pending recovery.
(No file system error. Can read, write, edit, and create files on the drive elsewhere as per usual practices)

* If the files have their owner set to a user other than you.
(Owner of all files is me. All files set to read/write for all users)

If your file is open in another program.
(No files open elsewhere)

* If the file resides on a device, you may have reached the limit of a maximum of 256 files in the root of the device. In this case you need to reformat the device/sd card referred to in the error message with a FAT32 filesystem, or delete some files from the SD card/device memory.
(Not applicable)

I am assuming that the Sequoia update introduced something new. Calibre was working as usual this morning and fails to work after updating the OS. I have downloaded a new Calibre package and reinstalled. I can confirm that other applications are able to access the directory as per usual.

Is volume(sda2) your boot disk? Default permissions for accessing the root of your disk have changed. See https://support.apple.com/en-us/101400

Try copying your entire Calibre library folder to inside your Documents folder.

e.g.

/Volumes/volume(sda2)/Users/<username>/Documents

and open it from there.

You could also try this in a terminal window:

ls -la /Volumes/volume(sda2)/Calibre*

to check file permissions.
