Hi, I'm a newbie with CentOS. Actually, with this generation Linux. I used it back in the middle 90's (Debian and Slackware) but migrated over to FreeBSD. I got tired of the dependency nightmares and wanted a system that "just worked". The FreeBSD ports system did just that for me. I HATE doing the rpm soup thing. RPM finders are nice but I'd rather just use something like the FreeBSD port system to handle all dependency issues for me. But I've slid back into Linux and found CentOS. Boy, have things changed a bit since I was last here :) I have to admit, yum gives me that functionality that I was very happy with FreeBSD - the ports system. It's not exactly the same but I LIKE yum a lot! I am noticing a couple of problems dealing with YUM that I hope you can help me with. I noticed that the default CentOS repositories that came on an install had a lot of the common packages but stuff like audacity and xawtv weren't there. But I figured that there was a repository that did have these. After some web searching, I found about the dag repository. I added the following into /etc/yum.repos.d/dag.repo as stated at http://dag.wieers.com/home-made/apt/FAQ.php : [dag] name=Dag RPM Repository for Red Hat Enterprise Linux baseurl=http://apt.sw.be/redhat/el$releasever/en/$basearch/dag gpgcheck=1 enabled=1 Now when I do a "yum list" I can find lots of the apps that I am looking for. But when I try to install packages I get things like: warning: rpmts_HdrFromFdno: V3 DSA signature: NOKEY, key ID 6b8d79e6 Public key for libquicktime-0.9.8-2.el4.rf.i586.rpm is not installed I can get installs to happen by changing the line in /etc/yum.respon.d/dag.repo from one to zero on the gpgcheck line. Questions: 1) Is dag a good repository to get me these apps that aren't part of the stock CentOS repository file? If not, which one should I use? I don't need bleeding edge (even two versions behind for an app would be fine). 2) What's up with the gpg failures? Should I be worried? 3) Finally, I'm trying to get xawtv to work. I ran "yum install xawtv" and all seemed to go fine. It found a bunch of dependencies and downloaded them from dag. Cool! But when I try to run xawtv I get: This is xawtv-3.94, running on Linux/i686 (2.6.9-34.EL) load_codec_info_from_plugin: dlopen failed for /usr/lib/libquicktime/lqt_ffmpeg.so: /usr/lib/libquicktime/lqt_ffmpeg.so: undefined symbol: avcodec_init Searching for this error has been less than fruitful. I realize this message has several questions in it. If you have opinions on ANY of the questions please feel free to respond. Yum and CentOS have me wanting to go back to Linux. If I can be taught how to use yum to install things "correctly" I think I'll be very happy back here. :-) Thanks in advance. - Damian
