I Update to DBeaver 21 on Mac OSX 11.2.1.
However after installing it I tried to install the Marketplace Client 1.8.2 & got the following error:
Cannot complete the install because of a conflicting dependency.

I downgraded to previous versions of DBeaver but unfortunatley get the same error.
It was also suggested that I run it from the command line as root so that it has correct permissions to save the files for the plugin install, but it still failed to install.
Thanks to @howgler for the answer. I also found the answer on DBeaver issues page on github. So the resolution is as follows.
Add the http://download.eclipse.org/mpc/releases/1.9.0 as source and then install the marketplace client from there.
