Calibre Library errors after NTFS > ext4 Conversion

[MontyJ]

I just completed dumping Windows 10 (dual boot with Mint Linux) for a Linux only setup.

As part of the process, I converted my Calibre libraries, which are on a separate large NTFS HD from the Linux system drive. I use the safe method of:

1. Copy all files and folders from NTFS drive to another hard drive
2. Format NTFS drive to Linux ext4
3. Copy all files and folders back onto the ext4 drive

The drives mount in /media/username/xxxxx and it mounts and displays files fine when I boot directly into Linux with no more dual-boot or Windows involvement; eBook epub and mobi files open and display correctly in other eReader apps.

But Calibre gives me a error when I try to change to the new libraries. The main error is:

calibre, version 1.48.0
ERROR: Unhandled exception: <b>IOError</b>:[Errno 13] Permission denied: u'/media/username/xxxxxx/Calibre Libraries/Calibre Master Fiction/calibre_test_case_sensitivity.txt'

The proper files appear to be there:

-rw-rw-rw- 1 username adm 54989824 Nov 1 16:35 metadata.db
-rw-rw-rw- 1 username adm 16816 Jul 26 09:26 metadata_db_prefs_backup.json

'username' is a member of 'adm' group as well.

There is more verbage to the error message and I will be glad to post if, but though this might be enough if someone has seen this before.

The file 'calibre_test_case_sensitivity.txt' is nowhere to be found, however. This makes me suspect it may be a Linux case sensitive issue, but no clue on how to troubleshoot further.

Thanks,

Monty

First update to latest calibre, then run library maintenance, you will have to do manual fixes for most of the problems.
Suggestion copy the library to a new library keeping current settings, then remove all books from the original library, check the old library with file manager, any folders books left in the old library need to be checked to see if they where copied over to the new.

Make backups before you start.

P.S.

I just copied my library from my mint 17 pc to a windows 10 tablet.

Thanks! I had just taken what was in the default repository, which appears to be pretty old, LoL.

Anyway, I thought it would simply update my current setup, but it gave me a whole new install. I have a pretty complicated setup/layout so would like to use my original config files, if that install link in your post didn't wipe it out! I backed out of the setup as soon as I saw the Wizard come up...

Can I still copy over the old config files or are they probably gone? What dir are they in in Linux?

[eschwartz]

The configuration directory is:

~/.config/calibre/   # Linux
%APPDATA%\calibre\   # Windows

If you copy it over, it should work more or less. One thing that will definitely break is the library locations, you will need to re-add them.


Installing the official binaries vs. the repository version will not interfere with your configuration!


The error message seems to imply that calibre cannot write a new file to the containing directory:

/media/username/xxxxxx/Calibre Libraries/Calibre Master Fiction/

Directories have write permissions too.


To fix permission issues with a shotgun use:

sudo chmod -R 644 /media/username/xxxxxx/Calibre Libraries/
sudo chmod -R a+X /media/username/xxxxxx/Calibre Libraries/
sudo chown -R username:username /media/username/xxxxxx/Calibre Libraries/

Those permissions changes you suggested did the Trick!! Much Thanks

You're welcome, and thanks for the karma.

On filesystems which understand permissions (unlike FAT32) if you are going to be switching OSes, user accounts, etc. I would always advise using the shotgun method of fixing permissions.
All kinds of things can go wrong when you accidentally mess up the permissions. And it's easy to get it wrong.
