Dash-to-dock: [Ubuntu 20.04 LTS] Error installing dash-to-dock; verbose build or logging available?

[yingw787]

Hello, I love this extension!

I just upgraded from Ubuntu 19.10 to Ubuntu 20.04 LTS (beta?) and I have an error loading the extension, both via chrome-gnome-tools and the GNOME website via Chrome, and via building from source on branch master commit 1788f31b049b622f78d0e65c56bef76169022ca9 using make && make install. Is there a way in order to build with verbosity included, or to see a log file somewhere? I would be better able to create bug reports with that.

Thank you!!

Ran git checkout ubuntu-dock-67ubuntu20.04.5, and then deleted the build artifacts and re-ran make && make install, and then ran sudo /etc/init.d/gdm restart, and it doesn't work. Awaiting response.

The below will disable the default ubuntu dock this should resolve the issue.
