If your Ubuntu version or derivative has not packaged the latest Inkscape, you can install the current version from our own Personal Package Archive (PPA).
Not all Ubuntu versions will be available, depending on how old your version of Ubuntu is. For older versions, please try the AppImage version or consider upgrading your system.
ppa:inkscape.dev/stable
sudo add-apt-repository ppa:inkscape.dev/stable sudo apt update sudo apt install inkscape
