On Ubuntu and various other Linux platforms, you can also use the snap package (installation instructions for snap).
On the terminal, type:
$ sudo snap install --candidate inkscape
If you already have the standard snap version of Inkscape installed, you can switch to regularly updated development versions for 1.0 (and later minor versions) with:
$ sudo snap refresh --candidate inkscape
You can then go back to the stable version with almost the same command:
$ sudo snap refresh --stable inkscape
