Ubuntu tweaks and install tricks

Preparations before install/upgrade

Backup files, esp. backup Evolution from inside the app to ease email client settings
Take note of special settings/credentials, e.g. Mobile Broadband, Wifi
If you use Syncthing and do a fresh Ubuntu install (not upgrade) it is safer to set up a new ID and symbolic name such as Machine2 from scratch so an empty file system don't get propagated accidentally as "delete all files"
Update Windows partition if any, including Lenovo firmware etc
Make sure you are up to date: sudo apt update && sudo apt full-upgrade -y && sudo update grub
Make a list of important programs installed and their install method, e.g. apt, ppa, snap, flatpak, deb-get, sdk, cs, brew, manual deb
