When all hardware available on (or accessible from) the system is directly supported (either as free software or from supplier support), the clean install is good solution. Unfortunately, my case is not like this. In my configuration exist build-in components with partial support and also some of my peripheral devices are without or buggy support. In many cases additional components and/or additional configurations are needed after install (done by hand). I don't want to repeat everything again (which is error prone). My current settings (and installed components) work well and I will try to keep this untouched, so clean install will be the 'extreme' thing (the last one) I will do. I rely that upgrade script fix ('/usr/bin/do-release-upgrade' - python script and/or related data) will be much simpler thing to do with some help here (probably one or few lines to be fixed).
Release file http://us.archive.ubuntu.com/ubuntu/dists/artful/Release is the one needed for the new release (one from all). The error message show that during upgrade (during prepare in fact) script rely to discover Release file in place like 'http://archive.ubuntu.com/ubuntu/dists/stable/'. Such place does not exist either on expected domain or on 'us.archive.ubuntu.com'. I am not sure, but it seems like 'http://archive.ubuntu.com/ubuntu stable Release' is wrongly formatted.
