从apt-get更新中删除Docker PPA

Question

当我运行apt-get update时，会得到一个错误和一个忽略：

Ign:14 https://download.docker.com/linux/ubuntu hera InRelease                         
Hit:15 https://download.docker.com/linux/ubuntu bionic InRelease                       
Hit:16 http://ppa.launchpad.net/elementary-os/stable/ubuntu bionic InRelease           
Err:17 https://download.docker.com/linux/ubuntu hera Release                           
  404  Not Found [IP: 13.226.234.100 443]

我希望能够从我的列表中删除14和17。但是，当我运行ls /etc/apt/sources.list.d时，我只看到以下内容：

appcenter.list                              mc3man-ubuntu-mpv-tests-bionic.list.save
appcenter.list.save                         openvpn-aptrepo.list
deadsnakes-ubuntu-ppa-bionic.list           openvpn-aptrepo.list.save
deadsnakes-ubuntu-ppa-bionic.list.save      patches.list
elementary.list                             patches.list.save
elementary.list.save                        rednotebook-ubuntu-stable-bionic.list
fcitx-team-ubuntu-nightly-bionic.list       rednotebook-ubuntu-stable-bionic.list.save
fcitx-team-ubuntu-nightly-bionic.list.save  slack.list
google-chrome.list                          slack.list.save
google-chrome.list.save                     spotify.list
mc3man-ubuntu-mpv-tests-bionic.list         spotify.list.save

我怎样才能移除这两项？

Answer 1

您可以使用add-apt-repository：

sudo add-apt-repository --remove 'deb [arch=amd64] https://download.docker.com/linux/ubuntu hera stable'

sudo add-apt-repository --remove 'deb [arch=amd64] https://download.docker.com/linux/ubuntu bionic stable'

Answer 2

我找到了存储在sources.list和sources.list.save中的存储库。要删除它们，我首先运行cd /etc/apt; grep -rI download.docker来查找存储库所在的文件，然后运行：

sudo nano /etc/apt/sources.list
sudo nano /etc/apt/sources.list.save

并删除了相应的行。
