外に出られない問題、Gatewayが192.168.1.1ではなく192.168.1.2だったからだった。アホすぎる。
Ubuntuのネットワーク管理、netplanとかいうものになっててよくわからない。

ダメですね。

NVIDIA-SMI has failed because it couldn't communicate with the NVIDIA driver. Make sure that the latest NVIDIA driver is installed and running.

通った！！
UbuntuにChromeインストール。
cd build
wget https://dl.google.com/linux/direct/google-chrome-stable_current_amd64.deb
sudo apt install ./google-chrome-stable_current_amd64.deb
stable-diffusion-webui-dockerが動いた。
後のためにまとめておこう。DHCP配下にあるマシンを、固定IPアドレスにして研究室サーバにぶら下げた。すると、ログインはできるが、git cloneができない。nslookupもできない。そもそも外にpingが通らない。sshはできているから、ネットワークに問題はないと考えた(これが敗因)。
まずありそうなのが、ファイアウォール。同じプライベート空間の他のマシンが大丈夫なので、マシン独自のファイアウォールが走っていることを疑うが、動いていない。
名前がひけないので、DNSを疑った。いろいろやったが、DNSを明示的に指定してnslookupしても届かない。ここでおかしいと思い始める。
最終的に、ping 8.8.8.8が通らないことで、絶対に変だと想う。ゲートウェイも少し疑ったのだが、netstat -rでは他のマシンのGatewayが
$ netstat -r
Kernel IP routing table
Destination Gateway Genmask Flags MSS Window irtt Iface
default gateway 0.0.0.0 UG 0 0 0 em1
192.168.1.0 0.0.0.0 255.255.255.0 U 0 0 0 em1
と、IPアドレスが見えないので、間違いに気づかなかった。
最終的に、無事なマシンで
$ sudo cat /etc/sysconfig/network-scripts/ifcfg-em1
(snip)
GATEWAY=192.168.1.2 # ←あっ！
要するに、デフォルトゲートウェイのIPアドレスが間違っていた。プライベートアドレス空間では問題なく通信できて、外に出られないのだから、真っ先にデフォルトゲートウェイを疑うべきだったな。
まぁ、今の僕の知識ではこれに最初から気づくのは無理だっただろう。SEは経験ですね。
論文紹介用の論文を探す x 2。
書籍。5章まで書いた。演習問題はまだ。
