![Docker 在 Ubuntu 19.10 上安装失败](https://linux22.com/image/924662/Docker%20%E5%9C%A8%20Ubuntu%2019.10%20%E4%B8%8A%E5%AE%89%E8%A3%85%E5%A4%B1%E8%B4%A5.png)
我曾经在 Ubuntu Server 19.10 上安装过旧版本的 docker,它运行得很好。我删除了这个旧的 docker 安装,并尝试使用https://docs.docker.com/engine/install/ubuntu/
当 containerd 服务无法启动时,安装会失败。尝试启动 containerd 时,会出现以下错误:
/usr/bin/containerd: symbol lookup error: /usr/bin/containerd: undefined symbol: seccomp_api_set
这是安装过程中的错误:
invoke-rc.d: initscript docker, action "start" failed.

答案1
我终于解决了这个问题。
首先,我使用以下方法搜索 libseccomp 相关目录
sudo find / -name '*libseccomp*'
我发现我安装了旧版本的 libseccomp,
/lib/x86_64-linux-gnu/libseccomp.so.2.3.1
并且/lib/x86_64-linux-gnu/libseccomp.so.2
我删除了这两个目录并重新启动,然后我就能够使用官方文档成功安装 Docker。

添加 Docker PGP 密钥:
curl -fsSL https://download.docker.com/linux/debian/gpg | sudo apt-key add -
配置docker apt存储库:
echo 'deb [arch=amd64] https://download.docker.com/linux/debian buster stable' | sudo tee /etc/apt/sources.list.d/docker.list
更新APT:
sudo apt-get update
如果您安装了旧版本的 Docker,请卸载它们:
sudo apt-get remove docker docker-engine docker.io
安装 Docker:
sudo apt-get install docker-ce
测试:
sudo docker run hello-world
启动Docker:
sudo systemctl start docker
在启动时启用docker:
sudo systemctl enable docker
允许非root用户使用docker:
sudo usermod -aG docker $USER
现在,注销并重新登录
