kubespray 和 python 包的问题

如何解决kubespray 和 python 包的问题

我想用 Kubernetes 安装 Kubespary，但我的 python 包有问题。我使用 Ubuntu 20.10 和 python3

ansible --version
ansible 2.9.6
  config file = /opt/kubespray/ansible.cfg
  configured module search path = ['/opt/kubespray/library']
  ansible python module location = /opt/ansible/lib/python3.8/site-packages/ansible
  executable location = /opt/ansible/bin/ansible
  python version = 3.8.6 (default,Sep 25 2020,09:36:53) [GCC 10.2.0]

pip3 freeze
ansible==2.9.6
cffi==1.14.4
cryptography==3.3.1
Jinja2==2.11.1
jmespath==0.9.5
MarkupSafe==1.1.1
netaddr==0.7.19
pbr==5.4.4
pkg-resources==0.0.0
pycparser==2.20
PyYAML==5.3.1
ruamel.yaml==0.16.10
ruamel.yaml.clib==0.2.2
six==1.15.0

当我使用此命令运行 ansible 角色时：

ansible-playbook -i inventory/mycluster/hosts.yaml --become --become-user=root cluster.yml 我有这个错误。

我该如何解决这个问题？ "msg": "No package matching 'python-apt' is available"} 谢谢。

解决方法

遇到同样的问题。原因应该是 ubuntu20.10 完全丢弃了 python2 存储库。 在 Ubuntu 20.04 上运行 apt list python-apt：

$apt list python-apt
python-apt/focal 2.0.0 amd64
python-apt/focal 2.0.0 i386

在 Ubuntu 20.10 上：

$apt show python-apt
Package: python-apt
State: not a real package (virtual)
N: Can't select candidate version from package python-apt as it has no candidate
N: Can't select versions from package 'python-apt' as it is purely virtual
N: No packages found
