Questions[ansible](ubuntu)

What I did:

sudo apt-add-repository ppa:ansible/ansible ; sudo apt update ; sudo apt install ansible

Error message:

Some packages could not be installed. This may mean that you have
requested an impossible situation or if you are using the unstable
distribution that some required packages have not yet been created
or been moved out of Incoming.
The following information may help to resolve the situation:

The following packages have unmet dependencies:
 ansible : Depends: python-paramiko but it is not installable
E: Unable to correct problems, you have held broken packages.

Description:
As you see, the problem is with the python-paramiko package. I tried to install the required package but it hasn't solved the problem.

In addition, none of the following related questions solved the problem.

• Unable to install ansible due to python dependency on Ubuntu 18.04
• Ansible from ppa won't install python-related packages

Thanks in advance.

I don't know why when I run my ansible-playbook to install packages on ec2-instances using apt-get this appears.[WARNING]: Updating cache and auto-installing missing dependency: python3-apt fatal: [localhost]: FAILED! => {"changed": false, "cmd": "apt-get update", "msg": "[Errno 2] No such file or directory: b'apt-get'", "rc": 2}.

Here is what my ansible code does to install packages on ubuntu.

 - name: Install packages for jenkins-docker-worker
hosts:
  - localhost
gather_facts: no

tasks:
  - name: Install docker
    apt:
      name: docker
      state: latest

  - name: start docker
    service:
        name: docker
        state: started

  - name: Ensure group "docker" exists
    group:
      name: docker
      state: present

I am using ansible for monitoring my home computing net, which consists several Linux machines (x64 and Raspberries). How can I avoid warnings from every Raspberry client?

[WARNING]: Platform linux on host raspi6.local is using the discovered Python interpreter at /usr/bin/python, but future installation of another Python interpreter could change this.

I try to reinstall ansible in my ubuntu18.04 laptop.

I've got this dependencies problem :

$ LANG=C sudo apt-get install ansible
Reading package lists... Done
Building dependency tree       
Reading state information... Done
Some packages could not be installed. This may mean that you have

The following information may help to resolve the situation:

The following packages have unmet dependencies:
 ansible : Depends: python-httplib2 but it is not going to be installed
           Recommends: python-winrm (>= 0.1.1) but it is not installable
E: Unable to correct problems, you have held broken packages.

So when I try this packet :

$ LANG=C sudo apt-get install python-httplib2
Reading package lists... Done
Building dependency tree       
Reading state information... Done
Some packages could not be installed. This may mean that you have

The following information may help to resolve the situation:

The following packages have unmet dependencies:
 python-httplib2 : Depends: python:any (< 2.8)
                   Depends: python:any (>= 2.7.5-5~)
                   Depends: ca-certificates but it is not going to be installed
E: Unable to correct problems, you have held broken packages.

Of course, python (2.7 & 3.6) and ca-certificates are well installed and functional.

When I try to install this packet via synaptic, Synaptic propose me to remove almost all the ubuntu packets :/

If I try to install manually the .deb from https://packages.ubuntu.com/bionic/libs/python-httplib2

I've got this :

$  LANG=C sudo dpkg -i Téléchargements/python-httplib2_0.9.2+dfsg-1_all.deb 
Selecting previously unselected package python-httplib2.
(Reading database ... 236487 files and directories currently installed.)
Preparing to unpack .../python-httplib2_0.9.2+dfsg-1_all.deb ...
Unpacking python-httplib2 (0.9.2+dfsg-1) ...
dpkg: dependency problems prevent configuration of python-httplib2:
 libssl1.1:amd64 (1.1.1-1ubuntu2.1~18.04.5) breaks python-httplib2 (<= 0.9.2+dfsg-1) and is installed.
  Version of python-httplib2 to be configured is 0.9.2+dfsg-1.

dpkg: error processing package python-httplib2 (--install):
 dependency problems - leaving unconfigured
Errors were encountered while processing:
 python-httplib2

this is certainly why, by removing libssl1.1:amd64 , synaptic want to remove all ubuntu...

I verify, all my packets are OK
- sudo apt install -f - sudo apt --fix-broken install - sudo apt install --reinstall libssl1.1 python-httplib2 - ... All the magic commands i usualy try to resolv this situation.

I find in /var/log/apt/* that 9 month a go, ansible was removed (with this famous python-httplib2 ) (I usualy don't use ansible from my laptop...):

I want to connect ansible to EC2 via ssh. I created a key pair on my local machine(ubuntu) and copied it to my EC2 instances using ssh-copy-id. The copy was successful, but I get the error below when I want to connect to my instance:

Failed to connect to the host via ssh: [email protected]: Permission denied (publickey)

when I inspected the auth.log file on my remote machine I see the following logs:

invalid user usuario from 187.xx.xx.xx port 47988

Here is my etc/ansible/hosts file

[host1]

github ansible_host=13.xxx.xxx.xx ansible_user=root

Any help will be appreciated. Thank you
