If your Ubuntu version or derivative has not packaged Inkscape 1.2.2 for you yet, you can install the current version from our ppa for Ubuntu 22.04, 20.04 and 22.10:

Command Line (any Ubuntu-based distribution):

… when you don't have Inkscape installed yet:

sudo add-apt-repository ppa:inkscape.dev/stable
sudo apt update
sudo apt install inkscape

… when you want to update your Inkscape installation from your distro's (deb-packaged) one to the ppa one:

sudo add-apt-repository ppa:inkscape.dev/stable
sudo apt dist-upgrade

In case of problems, make sure to remove your system's lib2geom package before retrying to install Inkscape from the ppa.
