I also have been experiencing this issue. I have Ubuntu 14.04 installed on a Laptop a Desktop and also in VirtualBox and they all are having the same problem.
I can copy files to an iomega NAS connected to a Linksys Router but I can not copy files from it. Regardless of what type or size of file that I try and copy from the NAS it fails with the “Software caused connection abort” error. This problem was not present in Ubuntu 12.04, 12.10, 13.04 and 13.10. This error is also not present in Windows 7 or Windows Vista. ** Attachment added: "Screenshot.png" https://bugs.launchpad.net/ubuntu/+source/nautilus/+bug/1312362/+attachment/4098212/+files/Screenshot.png -- You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to nautilus in Ubuntu. https://bugs.launchpad.net/bugs/1312362 Title: Can't copy a file from SMB share to the local file system: Software caused connection abort To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/nautilus/+bug/1312362/+subscriptions -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
