Hi ,all :

Today I run the "yum update" command on my laptop, which is CentOS 5.4 i386. Then the screen displays the following message :

root@kuku ~ > yum update Loaded plugins: fastestmirror Loading mirror speeds from cached hostfile * addons: mirror.centos.net.cn * base: mirror.centos.net.cn * epel: mirrors.sohu.com * extras: mirror.centos.net.cn * rpmforge: ftp-stud.fht-esslingen.de * rpmfusion-free-updates: mirrors.cat.pdx.edu * rpmfusion-free-updates-testing: mirrors.cat.pdx.edu * rpmfusion-nonfree-updates: mirrors.cat.pdx.edu * rpmfusion-nonfree-updates-testing: mirrors.cat.pdx.edu * update: mirrors.163.com Setting up Update Process Resolving Dependencies --> Running transaction check --> Processing Dependency: liblua-5.1.so for package: mysql-proxy ---> Package lua.i386 0:5.1.4-1.el5.rf set to be updated ---> Package lua-devel.i386 0:5.1.4-1.el5.rf set to be updated --> Finished Dependency Resolution mysql-proxy-0.5.1-1.el5.i386 from installed has depsolving problems --> Missing Dependency: liblua-5.1.so is needed by package mysql-proxy-0.5.1-1.el5.i386 (installed) Error: Missing Dependency: liblua-5.1.so is needed by package mysql-proxy-0.5.1-1.el5.i386 (installed) You could try using --skip-broken to work around the problem You could try running: package-cleanup --problems package-cleanup --dupes rpm -Va --nofiles --nodigest

Then I run "yum update --skip-broken", but after I run that command , the screen displays these:

Packages skipped because of dependency problems: lua-5.1.4-1.el5.rf.i386 from rpmforge lua-devel-5.1.4-1.el5.rf.i386 from rpmforge

Could someone give me some advices?

Thanks in advance ~
