+Description: Skip test failing in Ubuntu autopkgtest environment
+ The "Nanoc::CLI::Commands::View#run does not listen on non-local interfaces"
+ test tries to make use of a non-localhost IPv4 address associated to the
+ runner machine. However, in Ubuntu infrastructure this address is not allowed
+ by the $no_proxy variable. Moreover, this IP address is not predictable (it
+ might vary depending on the runner setup), therefore it cannot be manually
+ added to the test command.
