Installation complications
The first hurdle is always obtaining and installing the software.
The Linux Mint system package for Timewarrior was out of date, so we installed the latest version from Snap. The Hamster package in the distribution repository was the latest stable release (which is quite old), but we could also have installed via Flatpak, Snap or built from source code. There are installation instructions for Debian-based distros such as Ubuntu along with Fedora and OpenSUSE.
