System program problem detected in Ubuntu

Tags

operating system, problem, program, system, ubuntu

It’s a quite common problem we face in Ubuntu. Sometimes a program does not run in the proper way and crashes.

We don’t see immediately what are the repercussions.

After some time, a window pops up suddenly. It tells us “System program problem detected”. The window gives us two options – either we can cancel it, or we can report it to Ubuntu.

Whatever actions we take, this message persists, and keeps coming persistently.

What is the solution?

Open your terminal and issue the below command:

sudo rm /var/crash/*

It will clear all the ‘crashes’ that took place before.

Let me show you, before issuing this command, I also had had some same problems:

ss@ss-desktop:~$ cd /var/crash/
ss@ss-desktop:/var/crash$ ls
_usr_bin_gnome-shell.123.crash _usr_bin_Xwayland.123.crash
_usr_bin_gnome-shell.123.upload _usr_bin_Xwayland.123.upload
_usr_bin_gnome-shell.123.uploaded _usr_bin_Xwayland.123.uploaded
ss@ss-desktop:/var/crash$ sudo rm /var/crash/*
[sudo] password for ss:
ss@ss-desktop:/var/crash$ ls
ss@ss-desktop:/var/crash$

However, now I do not get that message any more.

 

 

Windows and Ubuntu installation problem

Considering installation of multiple Operating Systems in your PC or Laptop? Then this post might come to your help.
I have recently gone through a deadening installation process of two different types of Operating Systems – one is Windows 7 and the other is Ubuntu 16 – in my desktop. It shouldn’t have been deadening; as it’s normally very easy; all you need to do is follow few steps and you’re done within few hours. I’ve gone through many formatting in my life and for the first time I made a mistake.
Experienced and advanced Linux users often forget that Windows is an extremely selfish operating system. It doesn’t recognize any other operating system. And that’s the typical Microsoft way of thinking – we’re the king; there shouldn’t be any other partition except their own.

As you know Adminer is a parallel powerful database handling engine that works like phpMyAdmin.
Often we encounter a problem.
While upgrading our Linux system, we need to update the PHP or MySQL version. While doing this When we type: http://localhost/adminer.php to open Adminer, we encounter an error like this:

None of the supported PHP extensions (MySQLi, MySQL, PDO_MySQL) are available.

To handle this common error what can be done?
It can be solved by taking only two steps.

sudo apt-get install php7.0-mysqlnd

Next you have uncomment one line in ‘/etc/php/7.0/apache2/php.ini’. To do that open it in any editor;

sudo gedit /etc/php/7.0/apache2/php.ini

And just uncomment this line in Linux:


extension=msql.so


For Windows uncomment this line:


extension=msql.dll


That is all your Adminer will work fine.
