Update/Upgrade kernel on Ubuntu 16.04 server

This solves the issue where apt upgrade does not upgrade the kernel version.

Just doing apt upgrade won't work. We might need to give special attention to some packages.

sudo apt-get upgrade linux-generic linux-headers-generic linux-image-generic

Enable screenshot using in i3wm Debian KDE

mkdir -p ~/Pictures/Screenshots

Add the following lines in your i3 config:

# Printscreen controls (KDE)

i3 Dolphin icons not showing

Add the following line on your i3 config file

bindsym $mod+n exec bash -c "XDG_CURRENT_DESKTOP=KDE && dolphin"

Run using $mod+n

Take MySQL dump of a database or backup the database

mysqldump -u root -pYOUR-PASSWORD-HERE DATABASE-NAME > myDbData.sql

Todo:

sudo ./certbot-auto certonly -m [email protected] --agree-tos --manual --no-eff-email --manual-public-ip-logging-ok --preferred-challenges http  -d test1.example.com

This will give crt and key.
