I downloaded openSuSE 11.1 and burned a DVD and a CD with the non-OSS packages.
I first installed only a standard set of packages. When this went well, i.e. after I could boot succesfully, I installed more packages. yast tried to download them from some server and failed. So I changed the software repositories to only use my CD and DVD.
All went well until I tried to install Acroread. It told me that it needs several libraries it can’t find. I couldn’t install any of the other non-OSS packages either.
Well, I wouldn’t disable the update repo for one thing.
I see no reason to disable the online repos, unless you have a very small Internet plan. I installed acroread and it just worked. It might have fetched some dependencies from online repos, I didn’t pay attention. Perhaps there is a way with zypper to check which repos the dependencies of a package come from, it is not obvious from the man page.
