The upstream issue was fixed in 2015: https://github.com/hercules-team/augeas/pull/295 Tests: - In stable container, add options like [arch=amd64] to apt sources.list. - Enable package download through Tor. "tor+" is prepended to sources URL. - Disable package download through Tor. "tor+" is removed from sources URL.
