如何在 Ubuntu 18.04 上完全删除 Ansible 2.8.3

Question

在我的 Ubuntu 18.04 上，我安装了 Ansible 2.8.3。

[root:~] # ansible --version
ansible 2.8.3
  config file = None
  configured module search path = [u'/root/.ansible/plugins/modules', u'/usr/share/ansible/plugins/modules']
  ansible python module location = /usr/local/lib/python2.7/dist-packages/ansible
  executable location = /usr/bin/ansible
  python version = 2.7.15+ (default, Oct  7 2019, 17:39:04) [GCC 7.4.0]

当然我可以使用 apt 删除这个包

[root:~] # apt remove ansible
Reading package lists... Done
Building dependency tree       
Reading state information... Done
The following packages were automatically installed and are no longer required:
  python-httplib2 python-jinja2 python-markupsafe python-paramiko python-pyasn1 python-yaml sshpass
Use 'apt autoremove' to remove them.
The following packages will be REMOVED:
  ansible
0 upgraded, 0 newly installed, 1 to remove and 343 not upgraded.
After this operation, 58.0 MB disk space will be freed.

我可以安装不同的版本，例如 2.9.6

[root:~] # apt install ansible=2.9.6-1ppa~bionic

问题是安装2.9.6-1ppa~bionic只会带回 2.8.3 版本。

[root:~] # ansible --version
ansible 2.8.3
  config file = None
  configured module search path = [u'/root/.ansible/plugins/modules', u'/usr/share/ansible/plugins/modules']
  ansible python module location = /usr/local/lib/python2.7/dist-packages/ansible
  executable location = /usr/bin/ansible
  python version = 2.7.15+ (default, Oct  7 2019, 17:39:04) [GCC 7.4.0]
[root:~] #

所以结论一定是apt remove ansible不会完全删除2.8.3。如果apt install ansible执行另一个版本，此版本仍会安装准备激活。

有没有办法完全删除 Ansible 2.8.3？没有完全重新安装 Ubuntu 18.04？

顺便说一句，我使用官方 Ansible 存储库安装了 2.8.3

[root:~] # cat /etc/apt/sources.list.d/ansible.list 
deb      "http://ppa.launchpad.net/ansible/ansible/ubuntu" bionic main
[root:~] #  

使用 Chef BTW，我使用 Chef 管理我的所有系统。所以 Ansible 是使用 apt 和官方 Ansible 存储库安装的。

apt_repository 'ansible' do
  uri          'ppa:ansible/ansible'
  distribution node['lsb']['codename']
end
package ['ansible','python-pip']

就我而言，事实证明我已经通过 pip 安装了 ansible：

$ sudo apt remove ansible
Reading package lists... Done
Building dependency tree
Reading state information... Done
Package 'ansible' is not installed, so not removed

$ ansible --version
ansible 2.3.2.0
  config file = /etc/ansible/ansible.cfg
  configured module search path = Default w/o overrides
  python version = 2.7.17 (default, Apr 15 2020, 17:20:14) [GCC 7.5.0]

$ sudo pip uninstall --yes ansible
Uninstalling ansible-2.3.2.0:
  Successfully uninstalled ansible-2.3.2.0

$ ansible --version
-bash: /usr/local/bin/ansible: No such file or directory

所以尝试通过pip卸载ansible：

$ sudo pip uninstall --yes ansible
