download ubuntu8.04 iso

[Doug Pollard]

Got a mess here, have a lot of problems and getting worse.  Was trying 
to use kino to capture video  and could not capture. Used sudo  to dv 
capture files in my user home folder.  Bad move that!  Am getting error 
messages and having problems with with Firefox and cannot down load to 
desktop or other files.  I have so many problems I feel it best  to 
download Ubuntu 8.04.1 iso in synaptic and reinstall.  Have all my data 
saved on external hard drive.    The question is how or can I down load 
iso file on synaptic.??
                                                                        
           Thanks,  Doug
