Scribus 220.127.116.11 is in the VL repository under /extra. You may have to add that directory to your /etc/slapt-get/slapt-getrc file. As root add this line:
Then run gslapt, search for Scribus, and have gslapt install it.
Scribus 18.104.22.168 is not the latest version. The latest stable version is 22.214.171.124, which is not in our repositories. You can download a package for 126.96.36.199 from linuxpackages.net, but I don't know how it handles dependencies. Or you can compile 188.8.131.52 from source code.
