[ATrpms-users] [newbie] How did I kill my system with 'apt-get update'?

[Bill Stout]

I'm a first-time user of atrpms.net, followed
instructions and I killed my server.  What went wrong?

1st-> Followed instructions at:
http://atrpms.net/install.html

--Imported key
wget http://ATrpms.net/RPM-GPG-KEY.atrpms
rpm --import RPM-GPG-KEY.atrpms 

--Updated /etc/apt/sources.list:

# ATrpms for Fedora Core 1
# Possible sections: at-stable, at-good, at-testing,
at-bleeding
rpm http://apt.atrpms.net fedora/2/en/i386 at-testing
#rpm-src http://apt.atrpms.net fedora/2/en/i386
at-testing

2nd-> ran apt-get update
 *Everything looked OK*

3rd-> ran apt-get dist-upgrade
 *Things went to the crapper*

The following packages will be REPLACED: <blah>
The following NEW packages will be installed: <blah>
The following packages have been kept back <blah>

...ah...dammit...I'm running EL3.  Refer back to
phrase "This should NOT be done unless you know
exactly what you are doing!"

ok, is there a way to back out of this?  Or should I
copy off my config and data files and rebuild?
