Ubuntu advice

Runlevels

If you want to reboot to a console, just change the default runlevel. On next boot, it will boot to a console.

To change back to gui login..

sudo systemctl set-default graphical.target

Holding back upgrades

There are various ways to do this using dpkg, apt or other commands. These are just some places to start looking.

If there is a specific package that you don’t want upgraded, try configuring unattended upgrades:

/etc/apt/apt.conf.d/50unattended-upgrades

take a look at the sudo apt policy for the installed package, make note of the installed version:

sudo apt policy kubernetes

Take a look at the updates proposed:

sudo apt-get clean
sudo apt update
sudo apt list --upgradable

Finally, the update frequency must be defined in this file: /etc/apt/apt.conf.d/20auto-upgrades

sudo apt-mark hold kubectl sudo apt-mark showhold
