Hi folks,
I just started a brand new install with Core 5.0.2. Since I was dissatisfied with my current DE I decided to give e17 a try. Trying to install enlightenment.tcz failed when tce-load couldn't find libpaper.tcz in the repository. After trying again and then again with a different mirror, I just grabbed libpaper.tcz and libpaper.tcz.md5.txt from the 4.x repository. The installation went fine after that and e17 seems to be working pretty good. So it looks like the libpaper package can safely be copied over to the 5.x repo. (Unless the package managers built a new version and just forgot to upload it. If so, it would make more sense to use that build.)
Cheers,
lverns
