[SOLVED] - Could not open input file: bin/magento in localhost and Magento 2x

If you are getting this error 'Could not open input file: bin/magento' while trying to run certain magento commands in your terminal in localhost, then you can try this solution which worked for me.

I ran into this issue, because I'd accessed the root directory of my Magento installation from my terminal. Everything was working fine until now. I then deleted my Magento installation, created a new folder with the same name as the deleted folder. Now remaining in the same terminal window, without changing path or closing the terminal, I was trying to run the magento shell commands. This was the reason I was running into the above error.

To solve this issue, I simply closed my terminal, opened it again, checked into the root directory of my magento installation, and now the commands were running fine.

Also check, while at the Terminal, you are inside the Root Directory of your Magento Installation, else you will get this ERROR again.

[Solved] - Install PHP 7.0, PHP 7.1 or PHP 7.2 in Ubuntu 14.04

After trying a couple of packages, settings and configuration, the solution below is finally what worked for me:

1. Update your PPA repository with the  PHP 7x package sources:

 sudo add-apt-repository ppa:ondrej/php

Press enter to confirm. If you come across any error then you will need to install the python-software-properties first as shown below:

NOTE: The above PPA is a co-installable one, meaning you can install PHP 5.5, PHP 5.6 or PHP 7.0 as per your requirement, and both your old and new versions of PHP can co-exist without you having to remove the old version.

 sudo apt-get update  
 sudo apt-get install python-software-properties  

2. Update

Once again update your packages:

 sudo apt-get update  

3. Install PHP 7.x and its relevant mods:

For PHP7.0: sudo apt-get install php7.0 php7.1-mbstring php7.0-mcrypt php7.0-mysql php7.0-xml php7.0-curl php7.0-intl php7.0-soap php7.0-zip php7.0-gd
For PHP7.1: sudo apt-get install php7.1
For PHP7.2: sudo apt-get install php7.2

4. Disable PHP 5.5 or 5.6:

Now this step is very important else you won't be able to use PHP 5.6. Even when you check your PHP version, it will still display as PHP 5.5. Follow the step below to disable PHP 5.5.

 sudo a2dismod php5

 or

sudo a2dismod php5.6

5. Enable PHP 7.x:

Note: Replace x with 0, 1 or 2, depending upon the version you want to install

 sudo a2enmod php7.x  

6. Restart Apache web server:

 sudo service apache2 restart  

Note: New location of php.ini file in PHP 5.6:

The location of php.ini fie is changed from PHP 5.6 onwards, unlike PHP 5.5 where it used to be located at '/etc/php5/apache2/php.ini'; the new location is at '/etc/php/7.x/apache2'

[SOLVED]-Remove AppImage Desktop Integration

To remove the desktop integration for your AppImage, follow the instruction below:

Since an AppImage is not "installed", you don't need to "uninstall" it. Just delete the AppImage file and the application is gone. Additionally you may want to remove menu entry by deleting the desktop file from $HOME/.local/share/applications/.
