docker配置倉儲庫時出錯：無法安全地用該源進行更新，是以預設禁用該源

在Ubuntu上安裝docker，配置倉儲庫時第一次使用了阿裡去的鏡像，如下

?

1	sudo add-apt-repository "deb [arch=amd64] http://mirrors.aliyun.com/docker-ce/linux/ubuntu $(lsb_release -cs) stable"

 結果出現了以下錯誤：

2 3 4 5 6 7 8 9 10 11 12 13 14

misland@misland-virtual-machine: /etc/apt $ sudo add-apt-repository "deb [arch=amd64] http://mirrors.aliyun.com/docker-ce/linux/ubuntu $(lsb_release -cs) stable" 命中:1 http: //cn .archive.ubuntu.com /ubuntu bionic InRelease                                                                                                                                                      忽略:2 http: //ppa .launchpad.net /chris-lea/node .js /ubuntu bionic InRelease                                                                                                                                        擷取:3 http: //security .ubuntu.com /ubuntu bionic-security InRelease [83.2 kB]                                                                                                                                     擷取:4 http: //cn .archive.ubuntu.com /ubuntu bionic-updates InRelease [88.7 kB]                                                                                                                                     命中:5 https: //dl .yarnpkg.com /debian stable InRelease                                                                                                                                                             錯誤:6 http: //ppa .launchpad.net /chris-lea/node .js /ubuntu bionic Release                                                                                                                                           404  Not Found [IP: 91.189.95.83 80] 命中:7 http: //mirrors .aliyun.com /docker-ce/linux/ubuntu bionic InRelease                                                                                                                                          命中:8 http: //packages .microsoft.com /repos/vscode stable InRelease                                                                                                                                                正在讀取軟體包清單... 完成                                                                                                                                                                                        E: 倉庫 “http: //ppa .launchpad.net /chris-lea/node .js /ubuntu bionic Release” 沒有 Release 檔案。 N: 無法安全地用該源進行更新，是以預設禁用該源。 N: 參見 apt-secure(8) 手冊以了解倉庫建立和使用者配置方面的細節。

顯示是連接配接 到download.docker.com時失敗，無法下載下傳，試了N次，始終不行，換了各種鏡像，都 不行，坑的不要不要的，最後終于注意到一句話：

E: 倉庫 “http: //ppa .launchpad.net /chris-lea/node .js /ubuntu bionic Release” 沒有 Release 檔案

 配合上面 的錯誤 6，我決定搜一下這個問題，最終找到 了這個連結

按照這個哥們 的說法，這些舊的什麼 鬼ppa會導緻 很多問題，要把這些東西删掉，先找到這些無法使用的，使用如下 指令：

sudo apt-get update | grep "Failed"

 回車執行輸出如下：

sudo apt-get update | grep "Failed" E: 倉庫 “http: //ppa .launchpad.net /chris-lea/node .js /ubuntu bionic Release” 沒有 Release 檔案。

 于是按照上面哥們 說的，執行下面指令：

sudo add-apt-repository --remove ppa:chris-lea /node .js

 回車解除安裝。解除安裝 後再次執行阿裡去的倉儲庫，成功！

感謝上面的哥們！
