<p>I thought that my recent experiences upgrading my Linuxmint
desktop and my Ubuntu server might give others confidence to do it
themselves.</p>
<p><b>I upgraded Linuxmint from 20.3 to 21 without any problems
simply by</b></p>
<p>sudo apt update && sudo apt upgrade && sudo apt
autoclean && sudo apt autoremove</p>
<p>sudo apt install mintupgrade</p>
<p>sudo mintupgrade</p>
<p><b>I upgraded Ubuntu Server from 20.04 to 22.04.1 LTS (with only
a PHP problem) by</b></p>
<p>sudo apt update && sudo apt upgrade && sudo apt
autoclean && sudo apt autoremove</p>
<p>sudo do-release-upgrade</p>
<p>(Note: it is recommended not to do this over SSH)</p>
<p>Both upgrades automatically updated my PPAs too.</p>
