read only on copied file
 

running ubuntu on pc...copied a trust file to new file which now bars changes as "read only"..need to make it write....browser gave confusing instructions.

It's likely a issue with the ownership or permissions of the file.

In a terminal, cd to the directory which contains the file, then run the command

That will reveal the ownership and permissions attached to the file.
