Once again, this is just so that I don’t forget 🙂
apt -y update && apt -y upgrade && apt -y dist-upgrade && apt -y autoremove && apt -y clean && apt -y purge && reboot
Because you just want keep your system updated … I’m sure some of the commands are redundant, but hey.. It works!
When you login to your system and /boot is full, don’t panic!
Run this command and lean back, take a cup of coffee and relax, breath!
dpkg -l linux-* | awk '/^ii/{ print $2}' | grep -v -e `uname -r | cut -f1,2 -d"-"` | grep -e [0-9] | xargs sudo apt-get -y purge
When it’s done, it’s a good idéa to:
apt-get update && apt-get upgrade && apt-get dist-upgrade
Once again, lean back, take a cup of coffee, find your inner zen!

If you like me stumble upon a machine running a version of Ubuntu that has become depreciated (End of Life), then fear not!
The first way I’ve noticed that something was wrong, was when I ran “apt-get update” and got a bunch of “404”‘s from our update server. But after some searching on the web I found that you can just replace the “archive.ubuntu.com” to “old-releases.ubuntu.com” in your /etc/apt/sources.list and use Ubuntu:s archive server to update your machine to the “latest and greatest” for your release.
sudo sed -i -re 's/([a-z]{2}\.)?archive.ubuntu.com|security.ubuntu.com/old-releases.ubuntu.com/g' /etc/apt/sources.list
sudo apt-get update && sudo apt-get dist-upgrade
You should now have a system that is as much up to date as possible, please consider doing a release upgrade now so you can continue to receive updates and security patches!
Once you have performed the above steps to switch to the old-releases mirrors, update the Update Manager and then do do-release-upgrade:
sudo apt-get update sudo apt-get install update-manager-core sudo do-release-upgrade
