Githubとの接続でremote errorがでる

Last updated at Posted at 2022-03-22

起きたこと

git fetchしようとしたら怒られた

$ git fetch
fatal: remote error: 
  The unauthenticated git protocol on port 9418 is no longer supported.
Please see https://github.blog/2021-09-01-improving-git-protocol-security-github/ for more information.

原因

エラーメッセージに書いてあるページに書いてあるとおり、暗号化されていないgitプロトコルが廃止されたため。

リモートURLがgitプロトコルになっていた

$ git remote -v
origin	git://github.com/hoge-dev/hoge.git (fetch)
origin	git://github.com/hoge-dev/hoge.git (push)

2022/03/15より永続的に廃止となったようなので、今回の怒られが発生した模様。

対策

Pullしかしていない運用で鍵の登録がめんどくさかったので、プロトコルをhttpsにして対応

$ git remote set-url origin https://github.com/hoge-dev/hoge.git
$ git remote -v
origin	https://github.com/hoge-dev/hoge.git (fetch)
origin	https://github.com/hoge-dev/hoge.git (push)

めでたし、めでたし。

※鍵が登録済みでPushもするならプロトコルはsshでいい

$ git remote set-url origin git@github.com:hoge-dev/hoge.git
