As for finding out what my "baseurl" is, I'm not sure I'm doing the right thing. I tried the command suggested, and I got the following result: [root at localhost ~]# grep http /etc/yum.repos.d/fedora.repo grep: /etc/yum.repos.d/fedora.repo: No such file or directory So I thought I'd look in my repos directory, but none of the files there are for fedora or freshrpms. [root at localhost ~]# cd /etc/yum.repos.d [root at localhost yum.repos.d]# ls CentOS-Base.repo kbsingh-CentOS-Extras.repo output.txt dag.repo kbsingh-CentOS-Misc.repo Also, based on what was suggested to me in this thread, I tried running 'shutdown now -Fr', and on reboot, the system did some kind of check, but returned no errors or anything. It kind of flickered to my GUI log in screen before I could see anything come of it. Then I tried running fsck on var as was also suggested. But that produced some kind of error: [root at localhost ~]# fsck /var fsck 1.35 (28-Feb-2004) e2fsck 1.35 (28-Feb-2004) fsck.ext2: Is a directory while trying to open /var The superblock could not be read or does not describe a correct ext2 filesystem. If the device is valid and it really contains an ext2 filesystem (and not swap or ufs or something else), then the superblock is corrupt, and you might try running e2fsck with an alternate superblock: e2fsck -b 8193 <device> And all this reminded me, I have a little extra space on my disk which is not partitioned: Disk /dev/hdb: 30.7 GB, 30738677760 bytes 255 heads, 63 sectors/track, 3737 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Device Boot Start End Blocks Id System /dev/hdb1 * 1 3644 29270398+ 83 Linux /dev/hdb2 3645 3737 747022+ f W95 Ext'd (LBA) Should I turn that into a Linux swap, and might that help with this YUM issue? A guy on this list gave me some instructions for doing that, but I got this error from fdisk: [root at localhost yum.repos.d]# fdisk /dev/hdb The number of cylinders for this disk is set to 3737. There is nothing wrong with that, but this is larger than 1024, and could in certain setups cause problems with: 1) software that runs at boot time (e.g., old versions of LILO) 2) booting and partitioning software from other OSs (e.g., DOS FDISK, OS/2 FDISK) Command (m for help): t Partition number (1-5): 2 Hex code (type L to list codes): 82 You cannot change a partition into an extended one or vice versa Delete it first.
