Make the output of the df command more friendly and less cluttered by creating a system-wide alias for it:

echo "alias df='df -h -x squashfs -x tmpfs -x devtmpfs'" >> /etc/profile.d/aliases.sh

Make sure to set the “always_set_home” variable in the sudoers file (using visudo)

The recommend method to disable IPv6 on Ubuntu 18.04 after reboot is to configure the GRUB boot loader to pass kernel parameter during the boot time.

To do so open the /etc/default/grub file using your favorite text editor with root privileges and change/add:

FROM:
GRUB_CMDLINE_LINUX_DEFAULT=""
GRUB_CMDLINE_LINUX=""
TO:
GRUB_CMDLINE_LINUX_DEFAULT="ipv6.disable=1"
GRUB_CMDLINE_LINUX="ipv6.disable=1"

Once you have made the above change within the /etc/default/grub file execute the following commands to apply the GRUB changes:

sudo update-grub

Edit the /etc/default/grub file using your favorite text editor with root privileges and add the string consoleblank=600 to the GRUB_CMDLINE_LINUX_DEFAULT and GRUB_CMDLINE_LINUX lines for a 10-minute timeout. Save the file and apply the GRUB changes:

sudo update-grub

sudo apt-get install samba cifs-utils

sudo apt-get install nfs-common nfs-kernel-server

sudo apt install mysql-server
sudo mysql_secure_installation

Put any customization data into /etc/motd

sudo apt update
sudo apt install apache2
sudo apt install php libapache2-mod-php
sudo apt install php-mysql php-gd php-xml
sudo apt install phpmyadmin php-mbstring php-gettext

sudo apt update
sudo apt install phpmyadmin
mysql
mysql> ALTER USER 'root'@'localhost' IDENTIFIED WITH mysql_native_password BY '<password>';

The trouble in this case is with the needrestart command, which is part of the apt-get upgrade process in Ubuntu now. By default this is set to “interactive” mode which causes the interruption of scripts.

To change this behavior, we can edit the /etc/needrestart/needrestart.conf file, changing the line:

#$nrconf{restart} = 'i';

to

$nrconf{restart} = 'a'; (if we want to restart the services automatically) or $nrconf{restart} = 'l'; to simply list the services that need restart.
