The problem we had in the past is that nscd would cache lookup failures that happened when the Internet connection was missing, which made subsequent lookups fail even though networking was back up: http://bugs.gnu.org/22209 I believe this was fixed by commit c96ba2cf5efc0ee5c10f0a49aeaa9a45a84de7ed. It would be great if you could check whether the problem is reproducible, even with a stable connection. If it is indeed reproducible, then you could try running the installation after turning nscd off with: herd stop nscd Thanks, Ludo=E2=80=99.
