I am getting the error message: dpkg: unrecoverable fatal error, aborting:
files list file for package 'nautilus-sendto-empathy' is missing final newline
E: Sub-process /usr/bin/dpkg returned an error code (2), when I try to upgrade, or download software. Since I upgraded from 12.04 to 12.10, I have continually received system error messages on-screen when I log in, though this is after I go on Firefox, and it may be a Firefox error. But I am unable to update any software ever since the upgrade. I have fiddled about a bit, and unticked some items in the software system settings. Now the error message I get is the one you see above.
Would it be better if I reinstalled my good old 12.04? I am not very good with technology and need to be 'led'.
Thanks for your thoughts.
