That is correct. You are using Debian Stable 6.0.5 (aka "Squeeze"). Debian 7.0 (aka "Wheezy") is still in testing, but IS due to migrate to stable in a few months. You can either update to Wheezy now or wait until it becomes stable, depending on your preferences. > > When I try to update the Synaptic Package Manager I get some error > messages that don't mean anything to me at this stage in my > understanding (?). > > Here are the error messages: > > Ignoring file 'opera.list.save' in directory '/etc/apt/sources.list.d/' > as it has an invalid filename extension > > Ignoring file 'opera.list.save' in directory '/etc/apt/sources.list.d/' > as it has an invalid filename extension Not a problem. I believe there's some software (it might be synaptic, I'm not sure) which makes back-ups of your apt-sources.

According to "whois", multimedia.org is hosted by a domain-parking name server. Probably you meant deb-multimedia.org? But there isn't[1] a US mirror for them, so I'm not sure. > > Some index files failed to download, they have been ignored, or old > ones used instead. > > The /etc/apt/sources.lst is: > > # > > # deb cdrom:[Debian GNU/Linux 6.0.5 _Squeeze_ - Official amd64 DVD > Binary-1 20120512-14:34]/ squeeze contrib main > > # deb cdrom:[Debian GNU/Linux 6.0.5 _Squeeze_ - Official amd64 DVD > Binary-1 20120512-14:34]/ squeeze contrib main > > deb http://security.debian.org/ squeeze/updates main contrib > deb-src http://security.debian.org/ squeeze/updates main contrib > non-free > > # squeeze-updates, previously known as 'volatile' > # A network mirror was not selected during install.

While this[1] is marked as "obsolete", it's still a good starting place. [1] http://deb-multimedia.org/debian-m [2] http://www.debian.org/doc/manuals/apt-howto/
