Well it was good info maybe a little overwhelming to me right now. I have it bookmarked and will read it again tonight. I've been really busy today so I skimmed it while I should have sat down and read it. What it is with me is that I've used Linux since 2004 starting with puppy linux. Of course, like alot of ppl, I've tested and played around with quite a few distros I guess I'm a little spoiled on the ubuntu based Mint editions. I'm learning more about differences in deb packages. For instance, earlier today I got on sourceforge looking for kflickr now they had a ubuntu deb (I'm amd64 btw) but I read somewhere that LMDE is compatible with Debian, which isn't compatible with Ubuntu. so rather than download the Kflickr.amd64-ubuntu.deb I downloaded the source tar.gz (which compiled nicely) I wasn't sure if the ubuntu deb would work or not...
I'm trying to watch what I install but so far everything seems to be stable with this KDE so far... of course I have everything backed up on other partitions anyway so if this breaks than I'm not out much. (Not that I'm trying to screw it up)
so here is my sources.list now-----
debian main upstream import universe multiverse
testing main contrib non-free
testing/updates main contrib non-free
testing main non-free
#from the FAQ page
squeeze-updates main contrib non-free
if memory serves backports are recompiled packages from testing (mostly) and unstable (correcrt?)
sudo apt-get -f install and sudo aptitude -f install come back ok... again bear with me. I'm not expert but am always willing to learn new things about Linux and remain enthusiastic about this.
