$ sudo snap install chromium
$ chromedriver

The root cause is the following commit:

We need to check if $SNAP_USER_COMMON/.cache exists first.

Hi Sergio,

I forgot to ask, is this a part of snapd, and we need a new snapd release, or is this a part of build-time of snap packages and we need e.g. a new chromium snap with a fixed snapcraft version?

Thanks

It is part of snapcraft, and the script is added to the chromium snap (to be precise, it is added to any snap that uses the gnome-XX-YYYY extension). So you need a new chromium snap with the fixed snapcraft.

Ok, I was mistaken: it is part of the Gnome-XX-YYYY itself, and doesn't depend on snapcraft. So a rebuild of that snap should fix it, without having to create a new snap for chromium.
