Comment 5 for bug 482701

'cp' does not ignore case. It may well happen that the target filesystem is case-insensitive, or case-confused -- and 'cp' will be hit by an error like you reported. This is not a coreutils issue, but a limitation of the target filesystem.

No matter what (and even if 'cp' was indeed at fault) we would need detailed data to follow this up:

* target filesystem type
* exact command issued and responses
* Ubuntu and coreutils versions (as shown via 'dpkg -l coreutils' and 'lsb_release -a').

For the new issues, I suggest opening new bugs, after verifying it is not a target filesystem limitation).

Closing INVALID; please reopen if you do not agree, or have additional information.
