xiota [1] filed a deletion request for cairo-ubuntu [2]: Orphaned, outdated package. Although the package name and description state that the source of the patches is Ubuntu, I could trace only one back to Ubuntu, and it was dropped 6-7 years ago. Two of the patches appear to address issues that have already been fixed upstream. The remaining patch overrides a native cairo preference with one set in another program.
