Ansible "msg": "Failed to find required executable pvs" - ansible-2.x

I'm using the following in Ansible 2.1 on OSX and getting the subject message:
lvg: vg=vgname pvs=pvname state=present
Bug? or what am I doing wrong.
This syntax was working OK with ansible 1.9.1

You have to ensure that the lvm packages are installed on your target system.
So add to your Ansible playbook something like this:
tasks:
- yum:
name: 'lvm*'
state: present

On Centos or Redha,
You can use:
sudo yum makecache
sudo yum install lvm if not found use
sudo yum install lvm2
Thanks

How to install ROS on Ubuntu 18.04?

Im running Ubuntu 18.04 and trying to install ROS for the first time on my machine. I have tried to follow the instructions at: http://wiki.ros.org/melodic/Installation/Ubuntu
I get stuck at this part.
sudo apt-get install ros-melodic-desktop-full
My attempts:
sudo apt -f install
sudo apt update --fix-missing
sudo dpkg --configure -a
sudo dpkg --remove --force-remove--reinstreq
sudo apt clean
sudo apt update
sudo rm /var/lib/apt/lists/lock
sudo rm /var/cache/apt/archives/lock
Nothing has worked so far.
Terminal commands:
$sudo apt-get install ros-melodic-desktop-full
Reading package lists… Finished
Builds dependency trees
Reading state information ... Finished
Some packages could not be installed. It may mean that you have requested
an impossible situation or, if you use the unstable distribution
that some necessary packages have not yet been created or moved
from "Incoming".
The following information may help to resolve the situation:
The following packages have dependencies that cannot be satisfied:
rose-melodic-desktop-full: Dependent on: rose-melodic-desktop but it will not be installed
Depending on: rose-melodic-perception but it will not be installed
Depending on: rose-melodic-simulators but it will not be installed
Depending on: ros-melodic-urdf-sim-tutorial but it will not be installed
E: Could not correct the problems, you have withheld broken packages.
Please help me install ROS
1 - After following ROS melodic Installation first steps (see link below), Try to install it with the link "click here" below the "sudo apt install ros-melodic-desktop-full" line
ROS melodic Installation page
If it's doesn't work
2 - check, "Software & Update" parameters
(if you cannot find it: launch "Ubuntu Software Center" and in the menu bar, on top, select "Software & Update")
In "Other Sofware" tab, the link
"http://pacckage.ros.org/ros/ubuntu bionic main"
is printed, and in "Autentication" tab a key from Open Robotics is printed
3 - Try to do 1- again, if it doesn't work, follow 4-
4 - In "Updates" tab, check "recommanded Updates", launch "Update Manager" and install updates (I don't do it properly on my PC)
5 - And finally you need to install manually rosdep with:
"sudo apt-get install python-rosdep"
Ubuntu (apt) does NOT allow packages with the same name but different versions to be installed.
Remove other versions first. For example: apt remove ros-desktop*
first of all install program on ubuntu.
sudo apt-get update
sudo apt-get upgrade
after update packet try follow the instructions at: enter link description here again
I got it working like so:
Install deps:
sudo apt install gazebo9-common libgazebo9-dev gazebo9 ros-melodic-gazebo-ros-pkgs ros-melodic-gazebo-dev ros-melodic-gazebo-ros-control ros-melodic-gazebo-ros ros-melodic-urdf-sim-tutorial ros-melodic-simulators
Install ros melodic
sudo apt-get install ros-melodic-desktop-full

Apache start libphp7.3.so not found

I have Install php 7.3 and apache2 but when I try to start apache2 , I have this error :
service apache2 start
apache2: Syntax error on line 146 of /etc/apache2/apache2.conf: Syntax error on line 3 of /etc/apache2/mods-enabled/php7.3.load: Cannot load /usr/lib/apache2/modules/libphp7.3.so into server: /usr/lib/apache2/modules/libphp7.3.so: cannot open shared object file: No such file or directory
I really don't know how to resolve this problem, I have tried to remove and reinstall without success.
You're getting that error because the PHP 7.3 library for Apache is not installed.
sudo apt install -y libapache2-mod-php7.3
The above command should fix it.
It solved my problem:
sudo add-apt-repository ppa:ondrej/php
sudo apt-get update
sudo apt-get install php7.3
sudo apt-get install php7.3-cli php7.3-common php7.3-json php7.3-opcache php7.3-mysql php7.3-mbstring php7.3-zip php7.3-fpm php7.3-intl php7.3-simplexml
sudo service apache2 restart
For me the problem was that I did not install apache tools for php.
On arch linux:
yaourt -S php-apache
After that, module appeared in the folder.
The best way not to make a mistake is to follow guide: https://wiki.archlinux.org/title/Apache_HTTP_Server#PHP

Install Adminer on Ubuntu 18.04 bionic

I'm trying to install Adminer from Ubuntu repository using:
sudo apt install adminer
Installation works fine but can't find the file /etc/adminer/apache.conf to use with Apache server. The folder /etc/adminer/ is empty and can't find it anywhere with find command.
Any help?
Thanks in advance.
In the next few steps, I'll show you how I installed adminer for Ubuntu 18.04.1 LTS .
After installation with apt package manager change into the adminer directory.
cd /usr/share/adminer
There you will find a file called compile.php.
Run the following command and the adminer-X.X.X.php (X.X.X for your version) file will be created.
sudo php compile.php
Create the apache adminer configuration file.
sudo echo "Alias /adminer.php /usr/share/adminer/adminer-X.X.X.php" | sudo tee /etc/apache2/conf-available/adminer.conf
Now you'll need to activate the configuration.
cd /etc/apache2/conf-available/
sudo a2enconf adminer.conf
Reload your apache webserver.
sudo systemctl reload apache2.
Test in your browser of choice (localhost/adminer.php)
This source was really helpful:
https://www.linuxhelp.com/how-to-install-adminer-on-ubuntu-16-04/
Install Apache:
sudo apt-get install apache2
Install PHP:
sudo apt-get install php libapache2-mod-php php-mysql
Install Adminer:
sudo wget "http://www.adminer.org/latest.php" -O /var/www/html/adminer.php
Once the installation completes, restart Apache.
sudo service apache2 restart
At this point, the setup is complete. You can access Adminer at the following address.
http://[SERVER_IP]/adminer.php

Uninstall MongoDB on Mac OS X

When I try to run mongod from the terminal, I get the following error:
2014-07-02T23:56:24.797-0700 [initandlisten] ERROR: listen(): bind() failed errno:48 Address already in use for socket: 0.0.0.0:27017
2014-07-02T23:56:24.797-0700 [initandlisten] ERROR: addr already in use
I recently realize that I have two versions of MongoDB on my Mac, and think this may be the source for the above error. (Plus, I do not need two version.) I tried Googling, but was not able to find clear directions on how I can uninstall. I have development version 2.7.0 AND 2.6.3.
Thanks so much in advance for the help!
Run the following commands to remove mongodb from the launch/startup and to uninstall it using Homebrew:
# See if mongo is in the launch/startup list
launchctl list | grep mongo
# Remove mongodb from the launch/startup
launchctl remove homebrew.mxcl.mongodb
# Kill the mongod process just in case it's running
pkill -f mongod
# Now you can safely remove mongodb using Homebrew
brew uninstall mongodb
Just double-check in /usr/local/bin/ to make sure that the mongodb commands are removed.
For uninstalling the community version, i found that the command brew uninstall mongodb-community worked for me
Nitin Jadhav version worked for me, brew uninstall mongodb kept given me Error: No such keg: /usr/local/Cellar/mongodb. I was removing a mongodb-community.
use cd /usr/local/Cellar then run ls -a and then run rm -rf mongodb-community to remove it
I would suggest navigating into your /usr/local/Cellar and run an ls -a, I had a community version of mongo installed that wasn't being picked up by the command given above. If you find any mongo versions there just rm -rf each instance
For those having this error in osx:
brew uninstall mongodb Error: No such keg: /usr/local/Cellar/mongodb
execute brew list | grep mongo
for example, it could show something like:
mongodb-community#4.2
mongodb-database-tools
mongosh
remove them with brew uninstall mongodb-community#4.2 mongodb-database-tools mongosh
Also execute launchctl remove homebrew.mxcl.mongodb as #anuvrat-tiku says in his answer.

Install rst2man failed for varnish agent [fix]

I'm trying install varnish agent on ubuntu server using virtual box. There is a message in the middle installation process that say "you need rst2man installed to make dist".
When I tried install rst2man using "sudo apt-get install rst2man" another message come in :
Reading package list....done
Building dependecy tree
Reading state information....done
E: unable to locate package rst2man
"unable to locate package rst2man" what does it mean ? anyone know ? please help.
Problem fix:
I tried to install python-docutils for the rst2man.
rst2man is a virtual package, then you need install python-docutils package than provide rst2man and utilities for the documentation of Python modules.
sudo apt-get install python-docutils
After install this package, try the command:
sudo which rst2man
python-docutils wasn't working for me
I had to install the package docutils-common
sudo apt-get install docutils-common
In case if you installing varnish-agent-2 - after
sudo apt-get install python-docutils
you should execute again
./configure
Working on CentOS and likely RHEL as well:
yum install python-docutils
