CentOS 7.1即将升级到7.2前的备忘录

想yum update一下，但是出现了一些错误

You could try using --skip-broken to work around the problem
You could try running: rpm -Va --nofiles --nodigest

这是因为
“Those kmod-nvidia packages were rebuilt to match the new 7.2 kernel. The old packages don’t work with the newer kernel so the new packages have a Require: to pull in the new kernel and to stop them from being put on until the new kernel is available. I would exclude it from the update for now. 7.2 should be available soon, the packages will be available first via the “CR” repo, usually about a week before they become available via the normal base/updates repos.”

就是说把新版的还没群发出来的软件们拿来装一下(不怕死的就装吧)

yum-config-manager --enable cr
yum update

装了似乎没事，我还活着

其他，找个repo装ffmpeg，似乎 nux-dextop 有
按照说明

yum -y install epel-release
rpm -Uvh http://li.nux.ro/download/nux/dextop/el7/x86_64/nux-dextop-release-0-5.el7.nux.noarch.rpm

yum install ffmpeg ImageMagick -y
