Thanks TJ Saunders, follow is his reply: Here's your culprit here. By default, proftpd does not allow overwriting of existing files (this includes appending to existing files); see:
http://www.proftpd.org/docs/directives/linked/config_ref_AllowOverwrite.html This means that adding e.g.: <Global> AllowOverwrite on </Global> to your proftpd.conf should help. And it's works. ** Changed in: proftpd-dfsg (Ubuntu) Status: New => Invalid -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1296488 Title: Can't replace exist file by mod-sftp To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/proftpd-dfsg/+bug/1296488/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
