Installing the latest update through GNOME Extensions causes installation error on 20.04.

Similar error is occurring when trying to update the extension on Arch Linux
I concur.
Error is

Guys, just do Alt+F2, type "r" and Enter. That will reload Gnome.
Or reboot, or logout/login.
I tried reloading Gnome and Rebooting and I still have the same problem. I remember encountering this exact same scenario a few months ago and to solve it I had to install an old version.
I also did an apt update/upgrade before, to make sure I have the latest gnome-tweaks
Same Problem With PopOs was working fine but after the update it's broken
Had the same issue, reloading Gnome Shell fixed it however. Still it is an issue that should be addressed as less experienced users will be confused and thus the reputation of Dash to Dock could suffer.
same problem on Fedora 32 with gnome-shell 3.36.6-1
Reloading Gnome did not fix the issue for me.
I end up with an empty black bar at the bottom of my screen.
Same problem on a fresh installation of Ubuntu 20.04.1. Install from https://extensions.gnome.org, red error. So I tried;
git clone https://github.com/home-sweet-gnome/dash-to-panel.git
make install
All went well, but still does not work! Still a red error at (extensions.gnome.org) dash to panel does not work! Dash to panel is greyed out in gnome tweaks. See screenshot attached

I eventually fixed it by downloading the latest version from GitHub.
That didn't work at first, but apparently enabling the extension somehow still tried to activate the older version instead of the one I downloaded.

I concur.
