The best way is to have a script in your home called update which will take care of updating everything. To invoke it, simply open a terminal with Win+T and run ~./update - easy and fast.

Create the following scripts:

~/shutdown:

#!/bin/bash
set -e -o pipefail
sudo shutdown -h now

~/reboot:

#!/bin/bash
set -e -o pipefail
sudo reboot

~/update:

#!/bin/bash
set -e -o pipefail
sudo apt update
sudo apt -V dist-upgrade
sudo apt autoremove --purge
sudo snap refresh
# clean residual config
sudo apt purge $(dpkg -l | grep '^rc' | awk '{print $2}')

To run these scripts without needing to type in root password, run sudo visudo and add this line:

mavi ALL=(ALL) NOPASSWD:/usr/bin/apt *, /usr/bin/snap refresh, /usr/sbin/shutdown -h now, /usr/sbin/reboot

Also make the scripts executable: chmod a+x shutdown reboot update
