Last week I completed a fresh install of Novell’s OES Linux from the SP2 .iso CDs, and used rug to update the server with all the available patches. I needed to install NSS, so I went into YaST to add the software, but the server kept hanging at the checking dependencies screen. Rebooting the server didn’t resolve this issue, and the log files didn’t shed any light on the source of the problem.
I was able to make YaST stop hanging by disabling my two installation sources. Apparently it hung trying to read sources that were no longer valid, specifically /media/cdrom. I deleted the original sources, and manually defined the location of my installation media as/media/cdrecorder. Once I did this, I was able to access the Install and Remove Software program again.
