The entry is here: https://github.com/travis-ci/apt-source-whitelist/blob/63454fd9da89fce908ab316a69defa28f34c1743/ubuntu.json#L2 { "alias": "avsm", "sourceline": "ppa:avsm/ppa", "key_url": null }, So I'm guessting it's just this one. -- Dr Thomas Leonard http://roscidus.com/blog/ GPG: DA98 25AE CAD0 8975 7CDA BD8E 0713 3F96 CA74 D8BA _______________________________________________ opam-devel mailing list [email protected] http://lists.ocaml.org/listinfo/opam-devel
