I installed DBeaver on Ubuntu via Snap (sudo snap install dbeaver-ce)). I could not access the .ssh folder for the key. I Googled and found this:
I installed the Snap Store app:
$ sudo snap install snap-store
And followed the instructions by AlainBenbassat. I was then able to access the .ssh directory and access my RDBS using DBeaver.
riednyko provided a CLI solution, but I decided to try the GUI solution provided by AlainBenbassat.
