The specific problem I had was due to the sparc64 installation requiring unstable repositories, which is apparently not very well supported in the Debian installer. I was able to get around this by just installing the minimal base system, booting into it, fixing the repositories manually, then installing the standard system package (i.e. what tasksel would install) by hand. I also needed to dig a bit to find a mirror carrying sparc64 packages. It should also be noted that the desktop tasks are currently uninstallable because certain packages are missing from sparc64, but that is a minor issue. > There's currently a lot of information on the sparc64 page () but I don't > know of anything specific to the Ultra 10.
