After selecting an ISO in the GUI, it failed to finish the process.

Hi, there! Can I confirm further? Looks like extracting ISO is successful, but copying isn't.

I think Customizer doesn't have permission to extract your ISO to your target directory i.e. external media or shared storage media. Where is your target directory?

P.S.: "target directory" means "working directory"

P.S.S: On second thought, it may not be working directory fault. But something is preventing Customizer from copying the extracted ISO to the working directory.

UPDATED 2015.04.15 I tried with various local working directories, including a non-existent ones, on the host machine but all could extract and copy ISO properly. So I estimate this issue has something to do with read/write permission on external storage media.

Yes, it is an external drive.

Right, that explains most of the story. Your external storage media is using fuseblk type, which refers to NTFS filesystem. This is particularly used in the environment of Windows operating system.

In my case, I have an external hard disk using vfat type, which refers to FAT32 filesystem. I did manage to reproduce similar error OSError: [Errno 13] Permission denied and the extract had failed worse than NTFS filesystem (it hungs and never complete).

The workaround? Two suggestions:

1. work on the local working directories, on the same storage media as host system, given that you still have sufficient free space i.e. at least twice as much as your ISO file size you want to remaster.
2. still want to use your external storage media? You can, but the media must be formatted^ to at least ext3 filesystem and it will work fine (I have tested this myself)

^ WARNING Format would mean all data will be lost, so make sure to backup data first!

Above all, this issue arises because of using non-Linux/Unix compatible filesystem, to remaster a Linux/Unix system--which doesn't sound approriate at first place.

If there is no further issue, you can close this.
