Force the use of IPv4 - you don't have v6 available.

It's right there in your output: `101: Network is unreachable`. Fix your network connection. Then apt will work.

Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
