截至昨天，更新我的 Debian 10+bpo 系統後，每當我嘗試git clone、git fetch或任何其他依賴網路的 git 操作時，我都會得到fatal: unable to access 'https://domain.example/repo.git': Failed sending HTTP2 data或fatal: unable to access 'https://domain.example/repo.git': Failed sending HTTP request，這取決於 git 伺服器是否支援 HTTP2 。有趣的是，如果我使用git://or ssh 方案而不是https://，命令會成功，可能是因為curl未使用。我嘗試停用 SSL 驗證git config --global http.sslVerify false但無濟於事。我也嘗試重新安裝、、、libcurl和，但這也沒有幫助。將 git 從 降級到也不起作用，我正在努力在不破壞系統的情況下降級庫。libgnutlslibnettlelibhogweed1:2.29.2-1~bpo10+11:2.20.1-2+deb10u3

清除我的gitconfig也沒幫助。
此時我不知所措，不確定是否需要更改某些內容或只是等待 git/curl 維護人員來解決此問題。
答案1
在另一台具有相同系統但git正常工作的電腦上，我比較了未升級的軟體包。
將libcurl3-gnutls降級到7.64.0-4+deb10u2，問題解決。
答案2
我在devuan上也遇到這個問題。只需清除 git 並從來源安裝它即可。更喜歡最後一個版本 https://www.digitalocean.com/community/tutorials/how-to-install-git-from-source-on-ubuntu-20-04-quickstart https://mirrors.edge.kernel.org/pub/software/scm/git/
將其解壓縮，例如，在 /tmp 中 cd 進入解壓縮資料夾 ./configure && make && sudo make install
那麼，哪個 git
