[ubuntu-uk] Error Message when updating

[Keith Gregory]

I install 7.10 on this laptop a few weeks ago and have not touched it 
since. Tonight on starting up I used Synaptic Package Manager to get the 
updates and received the following error message;

E: Could not open file 
/var/lib/apt/lists/archive.ubuntu.com_ubuntu_dists_gutsy_main_i18n_Translation-en%5fGB 
- open (2 No such file or directory)

Advice Please on error and where to report too.
