PermissionError

[thiagoc]

Getting this error when I extract some directory, but the files seems to be extracted correctly. Should I worry or my backups are safe?

As the traceback happened in xattr code, I would suspect it is unable to set extended attributes.

I see you ran that from your user account, so it it maybe does not have enough permissions if in that archive is any file that is not owned by your user. Retry using the root account?

Another issue could be that the filesystem you are working on does not support extended attributes (xattrs), check your mount options and your filesystem's capabilities.

Hmm, yes, I running the backup on a remote server with another user. When I extract the archive on the server with the correct user it works as expected. Anyway, this is a bug? I think it should print a friendly message at least.

[ThomasWaldmann]

Yes, it could be prettier, definitively.

OTOH, a traceback, although somehow ugly, is nice to debug issues as one sees quite good at what place in the code something went wrong and what precisely it was.
