問題

いつも通り、いや結構久々WSL2上でgit cloneをしてみたところ、clone出来ない事象が発生する。

XXXXXX@XXXXXX:~/git$ git clone https://github.com/The-Japan-DataScientist-Society/100knocks-preprocess.git

ちょっと前に実施した際は上手くいっていたので、設定の問題ではないはず。

うーん。zscalerね…。またか…。
しかもgitの再ビルドが必要なの…？

解決法

stackoverflowにはいくつかの解決法が書いてあるが、直近の方が望ましそうなので自分が上手くいった手順を記載する。

sudo apt remove git -y
sudo apt update && sudo apt upgrade

DEBIAN_FRONTEND=noninteractive

sudo apt install build-essential autoconf dh-autoreconf libcurl4-openssl-dev \
                 tcl-dev gettext asciidoc docbook2x install-info \
                 libexpat1-dev libz-dev -y

wget https://raw.githubusercontent.com/paul-nelson-baker/git-openssl-shellscript/master/compile-git-with-openssl.sh .

./compile-git-with-openssl.sh -skiptests

これをやってgit cloneを再度試してみる。

やったね！
