Describe the problem you're observing.

I try to init a repository on a mounted USB harddrive formatted with ntfs. It works as user admin/root but not as a user "borg-backup" that has full read/write access to the usb drive. Borg output is:

` Local Exception Traceback (most recent call last): File "borg/archiver.py", line 5115, in main File "borg/archiver.py", line 5046, in run File "borg/archiver.py", line 168, in wrapper File "borg/repository.py", line 198, in enter File "borg/repository.py", line 297, in create File "borg/repository.py", line 323, in save_config File "borg/platform/base.py", line 248, in exit PermissionError: [Errno 1] Operation not permitted: '/volumeUSB1/usbshare/borg/config-3aqcj0ga.tmp'

The user "borg-backup" has full access to '/volumeUSB1/usbshare/borg':

` borg-backup@DS716:~$ touch /volumeUSB1/usbshare/borg/test_for_permissions

borg-backup@DS716:~$ ls -l /volumeUSB1/usbshare/borg/test_for_permissions

-rwxrwxrwx 1 admin users 0 Jul 20 18:26 /volumeUSB1/usbshare/borg/test_for_permissions

borg-backup@DS716:~$ rm /volumeUSB1/usbshare/borg/test_for_permissions

borg-backup@DS716:~$ ls -l /volumeUSB1/usbshare/borg

Most likely this is not a borg issue and someone can lead me in the right direction to solve this permission error.

Can you reproduce the problem? If so, describe how. If not, describe troubleshooting steps you took before opening the issue.

yes, borg init doesn't complete as a non root/admin user.

Include any warning/errors/backtraces from the system logs

Likely a duplicate of #6786.

There has been another attempt to fix this, please test the code from PR #6935 #6936 #6940.

[ThomasWaldmann]

The code referred to by previous comment is in borg 1.2.3 release. Can you test it?

[ThomasWaldmann]

Guess this is solved?
