First you really need to do some reading and asking. The restricted repositories are no longer there. So they are commented out by default. Don't use them.
For the mirror catalogs, use the alternate one only. The ftp server has been giving problems for a while.
To get around this you can manually edit the /etc/apt/sources.list (as root) by adding http to the stanza's that don't have it. IE: instead of ftp://ftp
, have http://ftp
. That enables both and you only need one that works. When APT (Synaptic is only a GUI for it) finds a working repository it stops. It checks both entries and if either works it's happy.
Unless you've installed something from the Community Repositories (CR), do not enable them
Likewise the deb.multimedia repository.
On the first installation upgrade use the Command Line (CL) outside of X. IE: Ctrl+Alt+F1. (Unless you loose the Internet.) To get the Internet outside of X you can enable the CR and install ceni before you leave X. It will connect outside of X easily. It has to be run as root. Be sure to disable the CR before continuing. It's not recommended to leave them enabled during an upgrade.
From the CL become root and enter apt-get update (hit the Enter key)
Then enter apt-get dist-upgrade (hit the Enter key)
After this first upgrade if you need to install proprietary video drivers it's time to do so. Afterwards you can install most anything from debian, deb-multimedia, etc. Don't upgrade with the CR enabled. You're way better off only upgrading individual programs from them.
Yes, even I am dishonest. Not in many ways, but in some. Forty-one, I think it is.
