Hello, I have tried to upgrade Fedora 1 to Fedora 2 but had a problem. The yum.conf is [main] cachedir=/var/cache/yum debuglevel=2 logfile=/var/log/yum.log pkgpolicy=newest distroverpkg=fedora-release tolerant=1 exactarch=1 [base] name=Fedora Core 2 - i386 - Base baseurl=http://download.fedora.redhat.com/pub/fedora/linux/core/2/i386/os/ [updates-released] name=Fedora Core 2 - i386 - Released Updates baseurl=http://download.fedora.redhat.com/pub/fedora/linux/core/2/i386/os/ http://ftp.dulug.duke.edu/pub/fedora/linux/core/2/i386/os/ ftp://ftp.tu-chemnitz.de/pub/linux/fedora-core/2/i386/yum/os/ ftp://ftp.linux.ncsu.edu/pub/fedora/linux/core/2/i386/yum/os/ The problem is, even using the command below yum --exclude=Xtest --exclude=scilab --exclude=R --exclude=l ibmrproject-devel -y upgrade > /tmp/fedora_upgrade.log 2>&1 Gathering header information file(s) from server(s) Server: Fedora Core 2 - i386 - Base Server: Fedora Core 2 - i386 - Released Updates Finding updated packages Downloading needed headers Finding obsoleted packages Resolving dependencies .Package Xtest needs XFree86 >= 4.2.0, this is not available. Package scilab needs libtcl8.3.so, this is not available. Package R needs libtcl8.3.so, this is not available. Package scilab needs libtk8.3.so, this is not available. Package R needs libtk8.3.so, this is not available. Package libmrproject-devel needs libmrproject = 0.10, this is not available. However, I do have updated XFree86, tck, tcl, libmrproject, libmrproject-devel after using rpm -q to check. What should I do? Thanks, -- Zhu Wang
