以前 Raspberry Pi で起きたことが Linux Mint でも起きた。
$ npm install --global yarn
をすると次のエラーが出た。

Raspberry Pi のときは IPv6 を無効にしたけど、どうも /etc/hosts に IPv4 のアドレスを追加すると解決するらしいことがわかった。というわけでディグった。

これらを /etc/hosts に追加したら動いた。
続いて yarn install したら似たようなエラーが出たので、同様にディグった。

yarn は一度 CNAME を挟んでいるので、 /etc/hosts では 104.16.16.35 registry.yarnpkg.com の形で追加した。
ところで Linux Mint で www.google.com といったアドレスや IPv6 アドレスに ping しても通らない。 Windows だと ping www.google.com すると IPv4 のアドレスに ping されて、 ping 2001:4860:4860::8888 すると「要求がタイムアウトしました。」と出る。なにか設定が必要なのだろうか。後日調べるとしよう。
