> I'm wondering the cause for blocking Cataclysm. I don't see an Ubuntu package called that.[1]
Here[2] is the list of purged Ubuntu packages. Specific reasons for each package are not given, but they are grouped into "non-free packages", and "free software packages or metapackages only relevant to branding Ubuntu". I don't see cataclysm in there though.
