如何卸载docker引擎？
我已经安装了docker
curl -sSL https://get.docker.com/ | sh 当我试图卸载软件包时，我正面临着以下错误
$ sudo apt-get remove docker-engine Reading package lists... Done Building dependency tree Reading state information... Done The following packages will be REMOVED: docker-engine 0 upgraded, 0 newly installed, 1 to remove and 5 not upgraded. 1 not fully installed or removed.

我该如何卸载docker软件包？
我正在使用Ubuntu 15.04。
尝试一下
sudo mv /var/lib/dpkg/info/{packagename}.* /tmp/ sudo dpkg --remove --force-remove-reinstreq {packagename} sudo apt-get remove {packagename} sudo apt-get autoremove && sudo apt-get autoclean
我有同样的问题，但在Ubuntu 14.04。 我解决这个问题的方法是：
首先删除不好的链接：
sudo mv /var/lib/dpkg/info/{packagename}.* /tmp/ sudo apt-get remove {packagename}
所以现在你可以再次安装它：
sudo apt-get install docker-engine
就这样。
看起来不像Docker特定的问题，而是像一般的安装问题。
docker工人曾经在那台机器上工作过（例如：安装成功了吗？）
我会开始寻找Failed to stop docker.service: Unit docker.service not loaded ，看看是否导致了什么是错误的更多的见解。 似乎无法停止服务。
您可能需要阅读一些关于systemd的信息，我推荐此页面。 journalctl也可能有帮助，请看这里 。
接着：
- docker.service是否存在？
- 它可以被加载？
- 它的状态是什么？
- 它是什么意思，如果你开始呢？
- 停下来？
ps：不是全自动安装脚本的忠实粉丝。 我没有看到apt-get install docker-engine有什么问题…
如果您想删除 Docker Toolbox（ 包括Docker Engine ）的所有内容。
你可以执行这个shell脚本：
#!/bin/bash # Uninstall Script if [ "${USER}" != "root" ]; then echo "$0 must be run as root!" exit 2 fi while true; do read -p "Remove all Docker Machine VMs? (Y/N): " yn case $yn in [Yy]* ) docker-machine rm -f $(docker-machine ls -q); break;; [Nn]* ) break;; * ) echo "Please answer yes or no."; exit 1;; esac done echo "Removing Applications..." rm -rf /Applications/Docker echo "Removing docker binaries..." rm -f /usr/local/bin/docker rm -f /usr/local/bin/docker-machine rm -r /usr/local/bin/docker-machine-driver* rm -f /usr/local/bin/docker-compose echo "Removing boot2docker.iso" rm -rf /usr/local/share/boot2docker echo "All Done!"
如果你仍然有折旧的Boot2docker ，你也想摆脱它。
您可以通过执行以下shell脚本来卸载它：
#!/bin/bash # Uninstall Script if [ "$(which boot2docker)" == "" ]; then echo "boot2docker does not exist on your machine!" exit 1 fi if [ "${USER}" != "root" ]; then echo "$0 must be run as root!" exit 2 fi echo "Stopping boot2docker processes..." boot2docker stop && boot2docker delete echo "Removing boot2docker executable..." rm -f /usr/local/bin/boot2docker echo "Removing boot2docker ISO and socket files..." rm -rf ~/.boot2docker rm -rf /usr/local/share/boot2docker echo "Removing boot2docker SSH keys..." rm -f ~/.ssh/id_boot2docker* echo "Removing boot2docker OSX files..." rm -f /private/var/db/receipts/io.boot2docker.* rm -f /private/var/db/receipts/io.boot2dockeriso.* echo "Removing Docker executable..." rm -f /usr/local/bin/docker echo "All Done!"
